Abstract
This Quick-Start is a runnable example showing the functionalities of the SpliceWiz workflow. Version 1.9.0
Introduction
SpliceWiz is a graphical interface for differential alternative splicing and visualization in R. It differs from other alternative splicing tools as it is designed for users with basic bioinformatic skills to analyze datasets containing up to hundreds of samples! SpliceWiz contains a number of innovations including:
- Super-fast handling of alignment BAM files using ompBAM, our developer resource for multi-threaded BAM processing,
- Alternative splicing event (ASE) filters to remove problematic ASEs from analysis
- Group-averaged coverage plots: publication-ready figures to clearly visualize differential alternative splicing between biological / experimental conditions
- Interactive figures, including scatter and volcano plots, gene ontology (GO) analysis, heatmaps, and scrollable coverage plots, powered using the shinyDashboard interface
This vignette is a runnable working example of the SpliceWiz workflow. The purpose is to quickly demonstrate the basic functionalities of SpliceWiz.
We provide here a brief outline of the workflow for users to get started as quickly as possible. However, we also provide more details for those wishing to know more. Many sections will contain extra information that can be displayed when clicked on, such as these:

FAQ
What are the system memory requirements for running SpliceWiz
We recommend the following memory requirements (RAM) for running various
steps of SpliceWiz:
buildRef()
- Building human / mouse SpliceWiz reference: 8 gigabytes
processBAM()
- Processing small alignment (BAM) files (~20 million paired end reads): 8 gigabytes
- Processing large BAM files (~100 million paired end reads): 16 gigabytes
collateData()
- Collating routine experiments (e.g. 3 replicates, 2 conditions): 8-16 gigabytes
- Collating large experiments (20+ samples, using
lowMemoryMode=TRUE): 32 gigabytes - Collating large experiments (20+ samples, using
lowMemoryMode=FALSE): 8 gigabytes per thread
Differential analysis
- Differential analysis (routine experiments): 8 gigabytes
- Differential analysis (large experiments - 20+ samples): 16 gigabytes
- DESeq2-based differential analysis of large experiments: 32 gigabytes
How does SpliceWiz measure alternative splicing?
SpliceWiz defines alternative splicing events (ASEs) as binary events between two possibilities, the included and excluded isoform. It detects and measures: skipped (casette) exons (SE), mutually-exclusive exons (MXE), alternative 5’/3’ splice site usage (A5SS / A3SS), alternate first / last exon usage (AFE / ALE), and retained introns (IR or RI).
SpliceWiz uses splice-specific read counts to measure ASEs. Namely, these are junction reads (reads that align across splice sites). The exception is intron retention (IR) whereby the (trimmed) mean read depth across the intron is measured (identical to the method used in IRFinder).
SpliceWiz provides two metrics:
- Percent spliced in (PSI): is the expression of the included isoform as a proportion of both included/excluded isoform. PSIs are measured for all types of alternative splicing, including annotated retained introns (RI)
- IR-ratio: For introns, we also measure IR-ratios, which is the
expression of IR-transcript as a proportion of IR- and
spliced-transcripts. Spliced transcript expression is measured using
either
SpliceOverorSpliceMaxmethod (the latter is identical to that used in IRFinder)
Does SpliceWiz detect novel splicing events?
Novel splicing events are those in which at least one isoform is not an
annotated transcript in the given gene annotation. SpliceWiz DOES detect
novel splicing events.
It detects novel events by using novel junctions, using pairs of junctions that originate from or terminate at a common coordinate (novel alternate splice site usage).
Additionally, SpliceWiz detects “tandem junction reads”. These are reads that span across two or more splice junctions. The region between splice junctions can then be annotated as novel exons (if they are not identical to annotated exons). These novel exons can then be used to measure novel casette exon usage.
Workflow from a glance
The basic steps of SpliceWiz are as follows:
- Building the SpliceWiz reference
- Process BAM files using SpliceWiz
- Collate results of individual samples into an experiment
- Importing the collated experiment as an NxtSE object
- Alternative splicing event filtering
- Differential ASE analysis
- Visualization
Quick-Start
Installation
To install SpliceWiz, start R (devel version) and enter:
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("SpliceWiz")Setting up a Conda environment to use SpliceWiz
For those wishing to set up a self-contained environment with SpliceWiz
installed (e.g. on a high performance cluster), we recommend using
miniconda. For installation instructions, see the documentation on
how to install miniconda
After installing miniconda, create a conda environment as follows:
After following the prompts, activate the environment:
Next, install R 4.2.1 as follows:
NB: We have not been able to successfuly use r-base=4.3, so we recommend using r-base=4.2.1 (until further notice).
Many of SpliceWiz’s dependencies are up-to-date from the conda-forge channel, so they are best installed via conda:
conda install -c conda-forge r-devtools r-essentials r-xml r-biocmanager \
r-fst r-plotly r-rsqlite r-rcurlAfter this is done, the remainder of the packages need to be installed from the R terminal. This is because most Bioconductor packages are from the bioconda channel and appear not to be routinely updated.
So, lets enter the R terminal from the command line:
Set up Bioconductor 3.16 (which is the latest version compatible with R 4.2):
Again, follow the prompts to update any necessary packages.
Once this is done, install SpliceWiz (devel) from github:
The last step will install any remaining dependencies, taking approximately 20-30 minutes depending on your system.
Enabling OpenMP (multi-threading) for MacOS users (Optional)
For MacOS users, make sure OpenMP libraries are
installed correctly. We recommend users follow this guide, but the quickest way
to get started is to install libomp via brew:
Installing statistical package dependencies (Optional)
SpliceWiz uses established statistical tools to perform alternative
splicing differential analysis:
- limma: models included and excluded counts as log-normal distributions
- DESeq2: models included and excluded counts as negative binomial distributions
- edgeR: models included and excluded counts as negative binomial distributions. SpliceWiz uses the quasi-likelihood method which deals better with zero-counts.
- DoubleExpSeq: models included and excluded counts using beta binomial distributions
To install all of these packages:
Loading SpliceWiz
Details
The SpliceWiz package loads the
NxtIRFdata data package.
This data package contains the example “chrZ” genome / annotations and 6
example BAM files that are used in this working example. Also,
NxtIRFdata provides pre-generated mappability exclusion annotations for
building human and mouse SpliceWiz references
The SpliceWiz Graphics User Interface (GUI)
SpliceWiz offers a graphical user interface (GUI) for interactive users, e.g. in the RStudio environment. To start using SpliceWiz GUI:
Navigating the GUI
The SpliceWiz GUI uses the shinyDashboard interface. Use
the side menu on the left hand side of the interface to navigate across
the various sub-panels in the SpliceWiz GUI.

Building the SpliceWiz reference
Why do we need the SpliceWiz reference?
SpliceWiz first needs to generate a set of reference files. The
SpliceWiz reference is used to quantitate alternative splicing in BAM
files, as well as in downstream collation, differential analysis and
visualisation.
Using the example FASTA and GTF files, use the
buildRef() function to build the SpliceWiz reference:
ref_path <- file.path(tempdir(), "Reference")
buildRef(
reference_path = ref_path,
fasta = chrZ_genome(),
gtf = chrZ_gtf(),
ontologySpecies = "Homo sapiens"
)The SpliceWiz reference can be viewed as data frames using various getter functions. For example, to view the annotated alternative splicing events (ASE):
See ?View-Reference-methods for a comprehensive list of
getter functions
Using the GUI
After starting the SpliceWiz GUI in demo mode, click the
Reference tab from the menu side bar. The following
interface will be shown:
Building the SpliceWiz reference using the GUI
- The first step to building a SpliceWiz reference is to select a directory in which to create the reference.
- SpliceWiz provides an interface to retrieve the genome sequence (FASTA) and transcriptome annotation (GTF) files from the Ensembl FTP server, by first selecting the “Release” and then “Species” from the drop-down boxes.
- Alternatively, users can provide their own FASTA and GTF files.
- Human (hg38, hg19) and mouse genomes (mm10, mm9) have the option of further refining IR analysis using built-in mappability exclusion annotations, allowing SpliceWiz to ignore intronic regions of low mappability.
Load Demo FASTA/GTF (5), and then click
Build Reference (6)
Where did the FASTA and GTF files come from?
The helper functions chrZ_genome() and
chrZ_gtf() returns the paths to the example genome (FASTA)
and transcriptome (GTF) file included with the NxtIRFdata
package that contains the working example used by SpliceWiz:
What is the chrZ genome?
For the purpose of generating a running example to demonstrate SpliceWiz, we created an artificial genome / gene annotation. This was created using 7 human genes (SRSF1, SRSF2, SRSF3, TRA2A, TRA2B, TP53 and NSUN5). The SRSF and TRA family of genes all contain poison exons flanked by retained introns. Additionally, NSUN5 contains an annotated IR event in its terminal intron. Sequences from these 7 genes were aligned into one sequence to create an artificial chromosome Z (chrZ). The gene annotations were modified to only contain the 7 genes with the modified genomic coordinates.
What is the gene ontology species?
SpliceWiz supports gene ontology analysis. To enable this capability, we
first need to generate the gene ontology annotations for the appropriate
species.

What is Mappability and why should I care about it?
For the most part, the SpliceWiz reference can be built with just the
FASTA and GTF files. This is sufficient for assessment for most forms of
alternative splicing events.
For intron retention, accurate assessment of intron depth is important. However, introns contain many repetitive regions that are difficult to map. We refer to these regions as “mappability exclusions”.
We adopt IRFinder’s algorithm to identify these mappability exclusions. This is determined empirically by generating synthetic reads systematically from the genome, then aligning these reads back to the same genome. Regions that contain less than the expected coverage depth of reads define “mappability exclusions”.
See the vignette: SpliceWiz cookbook for details on how to generate “mappability exclusions” for any genome.How do I use pre-built mappability exclusions to generate human and mouse references?
For human and mouse genomes, SpliceWiz provides pre-built mappability
exclusion references that can be used to build the SpliceWiz reference.
SpliceWiz provides these annotations via the NxtIRFdata
package.
Simply specify the genome in the parameter genome_type
in the buildRef() function (which accepts
hg38, hg19, mm10 and
mm9).
Additionally, a reference for non-polyadenylated transcripts is used. This has a minor role in QC of samples (to assess the adequacy of polyA capture).
For example, assuming your genome file "genome.fa" and a
transcript annotation "transcripts.gtf" are in the working
directory, a SpliceWiz reference can be built using the built-in
hg38 low mappability regions and non-polyadenylated
transcripts as follows:
Process BAM files using SpliceWiz
The function SpliceWiz_example_bams() retrieves 6
example BAM files from ExperimentHub and places a copy of these in the
temporary directory.
What are these example BAM files and how were they generated?
In this vignette, we provide 6 example BAM files. These were generated based on aligned RNA-seq BAMs of 6 samples from the Leucegene AML dataset (GSE67039). Sequences aligned to hg38 were filtered to only include genes aligned to that used to create the chrZ chromosome. These sequences were then re-aligned to the chrZ reference using STAR.
How can I easily locate multiple BAM files?
Often, alignment pipelines process multiple samples. SpliceWiz provides
convenience functions to recursively locate all the BAM files in a given
folder, and tries to ascertain sample names. Often sample names can be
gleaned when: * The BAM files are named by their sample names,
e.g. “sample1.bam”, “sample2.bam”. In this case, level = 0
* The BAM files have generic names but are contained inside parent
directories labeled by their sample names, e.g. “sample1/Unsorted.bam”,
“sample2/Unsorted.bam”. In this case, level = 1
Process these BAM files using SpliceWiz:
pb_path <- file.path(tempdir(), "pb_output")
processBAM(
bamfiles = bams$path,
sample_names = bams$sample,
reference_path = ref_path,
output_path = pb_path
)Using the GUI
After building the demo reference as shown in the previous section,
start SpliceWiz GUI in demo mode. Then, click the
Experiment tab from the menu side bar. The following
interface will be shown:
The Experiment Panel - GUI
The buttons on the left hand side are as follows:
- Set the folders containing the SpliceWiz reference, BAM files, and the output (NxtSE) folder
- Run
processBAM(process BAM files) - Import annotations from a tabular text file (such as a csv file)
- Settings for
collateData- collating the experiment - Run
collateData(collating the experiment) - Import/Export current sample annotations from/to the NxtSE folder, or export annotations as a csv file
- Set the number of threads used to run
processBAMand `collateData functions
Also, (8) is a row of tabs that toggle between different tables, showing details of the Reference, BAM files, processBAM output Files, and sample Annotations
To continue with our example, click on (1)
Define Project Folders to bring up the following drop-down
box:
Define Project Folders
We need to define the folders that contain our reference, BAM files, as well as the experiment (NxtSE) output folder for the final compiled experiment
- Click on
Choose Reference Folderand select theReferencedirectory (where the SpliceWiz reference was generated by the previous step. Then, - Click on
Choose BAM Folderand select thebamsdirectory (where the demo BAM files have been generated). - Click on
Choose / Create Experiment (NxtSE) Folderand select theNxtSEdirectory (which should currently be empty except for thepbOutputsubdirectory). Note that when an Experiment folder is chosen via this step, apbOutputsubdirectory will be created if it does not already exist
After our folders have been defined, on the right hand side, an interactive table should be displayed that looks like the following:
Running processBAM
To process the example BAM files, first make sure the BAM files you
wish to process have been selected (BAM files can be unselected by
removing the ticks in the selected column). Also, users
have the option of renaming the samples (by setting the names in the
sampleName column).
To continue with our example, lets leave the names as-is. Click the
Process Selected BAMs button. A prompt should pop up asking
for confirmation. Click OK to start running processBAM.
What is the processBAM() function
SpliceWiz’s processBAM() function can process one or more
BAM files. This function is ultra-fast, relying on an internal native
C++ function that uses OpenMP multi-threading (via the
ompBAM C++ API).
Input BAM files can be either read-name sorted or coordinate sorted (although SpliceWiz prefers the former). Indexing of coordinate-sorted BAMs are not necessary.
processBAM() loads the SpliceWiz reference. Then, it
reads each BAM file in their entirety, and quantifies the following:
- Basic QC parameters including number of reads, directionality, etc
- Counts of gapped (junction) reads / fragments
- Intron coverage depths and other parameters (identical output to IRFinder)
- COV files (which are like BigWig files but record strand-specific coverage)
- Miscellaneous quants including coverage of chromosomes, intergenic regions, rRNAs, and non-polyadenylated regions
processBAM() generates two output files.
The first is a gzipped text file containing all the quantitation data.
The second is a COV file which contains the per-nucleotide
RNA-seq coverage of the sample.
More details on the processBAM() function
At minimum, processBAM() requires four parameters:
bamfiles: The paths of the BAM filessample_names: The sample names corresponding to the given BAM filesreference_path: The directory containing the SpliceWiz referenceoutput_path: The directory where the output ofprocessBAM()should go
pb_path <- file.path(tempdir(), "pb_output")
processBAM(
bamfiles = bams$path,
sample_names = bams$sample,
reference_path = ref_path,
output_path = pb_path
)processBAM() also takes several optional, but useful,
parameters:
n_threads: The number of threads for multi-threadingoverwrite: Whether existing files in the output directory should be overwrittenrun_featureCounts: (Requires the Rsubread package) runs featureCounts to obtain gene counts (which outputs results as an RDS file)
For example, to run processBAM() using 2 threads,
disallow overwrite of existing processBAM() outputs, and
run featureCounts afterwards, one would run the following:
# NOT RUN
# Re-run IRFinder without overwrite, and run featureCounts
require(Rsubread)
processBAM(
bamfiles = bams$path,
sample_names = bams$sample,
reference_path = ref_path,
output_path = pb_path,
n_threads = 2,
overwrite = FALSE,
run_featureCounts = TRUE
)
# Load gene counts
gene_counts <- readRDS(file.path(pb_path, "main.FC.Rds"))
# Access gene counts:
gene_counts$counts
Collate the experiment
The helper function findSpliceWizOutput() organises the
output files of SpliceWiz’s processBAM() function. It
identifies matching "txt.gz" and "cov" files
for each sample, and organises these file paths conveniently into a
3-column data frame:
Using this data frame, collate the experiment using
collateData(). We name the output directory as
NxtSE_output as this folder will contain the data needed to
import the NxtSE object:
nxtse_path <- file.path(tempdir(), "NxtSE_output")
collateData(
Experiment = expr,
reference_path = ref_path,
output_path = nxtse_path
)
What is the collateData() function
collateData() combines the processBAM() output
files of multiple samples and builds a single database.
collateData() creates a number of files in the chosen
output directory. These outputs can then be imported into the R session
as a NxtSE data object for downstream analysis.
At minimum, collateData() takes the following
parameters:
Experiment: The 2- or 3- column data frame. The first column should contain (unique) sample names. The second and (optional) third columns contain the"txt.gz"and"cov"file pathsreference_path: The directory containing the SpliceWiz referenceoutput_path: The directory where the output ofprocessBAM()should go
collateData() can take some optional parameters:
IRMode: Whether to use SpliceWiz’sSpliceOvermethod, or IRFinder’sSpliceMaxmethod, to determine total spliced transcript abundance. Briefly,SpliceMaxconsiders junction reads that have either flanking splice site coordinate.SpliceOverconsiders additional junction reads that splices across exon clusters in common. Exon clusters are groups of mutually-overlapping exons.SpliceOveris the default option.overwrite: Whether files in the output directory should be overwrittenn_threads: Use multi-threaded operations where possiblelowMemoryMode: Minimise memory usage where possible. Note that most of the collateData pipeline will be single-threaded if this is set toTRUE.
collateData() is a memory-intensive operation when run
using multiple threads. We estimate it can use up to 6-7 Gb per thread.
lowMemoryMode will minimise RAM usage to ~ 8 Gb, but will
be slower and run on a single thread.Enabling novel splicing detection
Novel splicing detection can be switched on by setting
novelSplicing = TRUE from within the
collateData() function:
# Modified pipeline - collateData with novel ASE discovery:
nxtse_path <- file.path(tempdir(), "NxtSE_output_novel")
collateData(
Experiment = expr,
reference_path = ref_path,
output_path = nxtse_path,
novelSplicing = TRUE ## NEW ##
)collateData() uses split reads that are not annotated
introns to help construct hypothetical minimal transcripts. These are
then injected into the original transcriptome annotation (GTF) file,
whereby the SpliceWiz reference is rebuilt. The new SpliceWiz reference
(which contains these novel transcripts) is then used to collate the
samples.
To reduce false positives in novel splicing detection, SpliceWiz provides several filters to reduce the number of novel junctions fed into the analysis:
- Novel junctions that are lowly expressed (only in a small number of
samples) are removed. The minimum number of samples required to retain a
novel junction is set using
novelSplicing_minSamplesparameter - Alternately, junctions are retained if its expression exceeds a
certain threshold (set using
novelSplicing_countThreshold) in a smaller number of samples (set usingnovelSplicing_minSamplesAboveThreshold) - Further, novel junctions can be filtered by requiring at least one
end to be an annotated splice site (this is enabled using
novelSplicing_requireOneAnnotatedSJ = TRUE).
For example, if one wished to retain novel reads seen in 3 or more samples, or novel spliced reads with 10 or more counts in at least 1 sample, and requiring at least one end of a novel junction being an annotated splice site:
By default, tandem junction reads (reads that align across two or
more splice junctions) are used to detect novel exons. This can be
turned off by setting novelSplicing_useTJ = FALSE.
nxtse_path <- file.path(tempdir(), "NxtSE_output_novel")
collateData(
Experiment = expr,
reference_path = ref_path,
output_path = nxtse_path,
## NEW ##
novelSplicing = TRUE,
# switches on novel splice detection
novelSplicing_requireOneAnnotatedSJ = TRUE,
# novel junctions must share one annotated splice site
novelSplicing_minSamples = 3,
# retain junctions observed in 3+ samples (of any non-zero expression)
novelSplicing_minSamplesAboveThreshold = 1,
# only 1 sample required if its junction count exceeds a set threshold
novelSplicing_countThreshold = 10 ,
# threshold for previous parameter
novelSplicing_useTJ = TRUE
# whether tandem junction reads should be used to identify novel exons
)Using the GUI to annotate the experiment
After running the Reference and processBAM steps as indicated in the
previous sections (of the GUI instructions), there is an option to
assign annotations to the experiment prior to collation. Annotations can
be assigned from existing tabular files (such as csv files). For this
example, we will demonstrate how to use a csv file containing
annotations to annotate our experiment. Note that the annotation table
should contain matching sample names in its leftmost column.
To select a file containing annotations, click on
Import Annotations from file, then select the
demo_annotations.csv file that should be in the working
directory. Press ok. Your interface should now look like this:
Importing annotations
Note that an extra button
Add / Remove Annotation Columns (*) has appeared. Clicking
on this button allows us to add/remove annotation columns
Adding annotation columns
Using the GUI to collate the experiment
After annotating the experiment in the step above, click on the
Experiment Settings button. Then enable
Look for Novel Splicing to bring up the following
display:
Customizing the Experiment Settings
This drop-down dialog box contains several parameters related to novel splicing detection:
- Toggle on/off novel splice detection
- Restrict novel junction reads to having one annotated splice site
- Filter novel junction counts based on the number of samples in which the novel junction was observed (any non-zero amount)
- Filter novel junction counts based on expression threshold (min number of samples set here)
- Threshold junction read count (expression threshold based novel junction filter)
- Whether to utilize tandem junction to define novel exons
Also, there is an option (7) to overwrite a previously-compiled NxtSE in the same folder. There is also an option to clear all the Reference/BAM/NxtSE folders (8).
For this example, we will leave the settings as above. Proceed to run
collateData() by clicking on Collate Experiment. After
several moments, a pop-up message should be shown when the experiment
has been successfully collated.
Importing the experiment
Before differential analysis can be performed, the collated
experiment must be imported into the R session as an NxtSE
data object.
After running collateData(), import the experiment using
the makeSE() function:
Using the GUI
After running the steps in the previous GUI sections, navigate to
Analysis and then click the Load Experiment on
the menu bar. The display should look like this:
Analysis - Loading the Experiment - GUI
The buttons on the left hand side are as follows:
- Select the NxtSE folder containing the collated experiment
- Import annotations from file (tabular format such as csv file)
- Load NxtSE from folder (into current session for downstream analysis)
- After NxtSE has been loaded, it can be saved as an RDS file to send
to collaborators (note that COV files will be disconnected once the file
has been moved to a different location; it is best to give your
collaborators the NxtSE folder instead, with the COV files inside the
pbOutputsubdirectory) - Load NxtSE from RDS file (saved via the prior step)
To continue with our example, click the
Select Experiment (NxtSE) Folder, then select the
NxtSE directory. The interface should now look like
this:
Loading the NxtSE after reviewing the samples and annotations - GUI
To view any existing annotations, click the Annotations
tab in the Experiment Display above the sample table. If
you followed the prior steps in the Collate the experiment
section, there should already be annotations here. If not, feel free to
add annotations using the Import Annotations from File (and
click on “demo_annotations.csv” file), or manually add and annotate
columns by clicking on the Add / Remove Annotation Columns
button to open the drop-down box.
To load the NxtSE object, click the
Load NxtSE from Folder to which will load the NxtSE object
into the current session. A pop-up will appear once the NxtSE object has
been successfully completed.
What is the makeSE() function
The
makeSE() function imports the compiled data generated
by the collateData() function. Data is imported as an
NxtSE object. Downstream analysis, including differential
analysis and visualization, is performed using the NxtSE
object.
More details about the makeSE() function
By default, makeSE() uses delayed operations to avoid
consuming memory until the data is actually needed. This is advantageous
in analysis of hundreds of samples on a computer with limited resources.
However, it will be slower. To load all the data into memory, we need to
“realize” the NxtSE object, as follows:
Alternatively, makeSE() can realize the NxtSE object at
construction:
By default, makeSE() constructs the NxtSE object using
all the samples in the collated data. It is possible (and particularly
useful in large data sets) to read only a subset of samples. In this
case, construct a data frame object with the first column containing the
desired sample names and parse this into the colData
parameter as shown:
subset_samples <- colnames(se)[1:4]
df <- data.frame(sample = subset_samples)
se_small <- makeSE(nxtse_path, colData = df, RemoveOverlapping = TRUE)RemoveOverlapping = FALSE.
Differential analysis
Assigning annotations to samples
NB: to add annotations via the GUI workflow, see the
Collate the experiment section.
Saving and reloading the NxtSE as an RDS file (GUI)
Once an NxtSE object has been loaded into memory, you can save it as an
RDS object so it can be reloaded in a later session. To do this, click
the Save NxtSE as RDS button. Choose a file name and
location and press OK. This RDS file can be loaded as an
NxtSE object in a later GUI session by clicking the
Load NxtSE from RDS button.
What is the NxtSE object
NxtSE is a data object which contains all the required data
for downstream analysis after all the BAM alignment files have been
process and the experiment is collated.

SummarizedExperiment object. This means that the functions
for SummarizedExperiment can be used on the NxtSE object. These include
row and column annotations using the rowData() and

Rows in the NxtSE object contain information about each
alternate splicing event. For example:

Also, NxtSE objects can be subsetted by rows (ASEs) or
columns (samples). This is useful if one wishes to perform analysis on a
subset of the dataset, or only on a subset of ASEs (say for example,
only skipped exon events). Subsetting is performed just like for
SummarizedExperiment objects:
# Subset by columns: select the first 2 samples
se_sample_subset <- se[,1:2]
# Subset by rows: select the first 10 ASE events
se_ASE_subset <- se[1:10,]
Filtering high-confidence events
SpliceWiz offers default filters to identify and remove low confidence alternative splice events (ASEs). Run the default filter using the following:
se.filtered <- se[applyFilters(se),]
#> Running Depth filter
#> Running Participation filter
#> Running Participation filter
#> Running Consistency filter
#> Running Terminus filter
#> Running ExclusiveMXE filter
#> Running StrictAltSS filterUsing the GUI
After following the GUI tutorials in the prior sections, click on
Analysis and then Filters from the menu bar.
It should look like this:
Analysis - Filters - GUI
To load SpliceWiz’s default filters, click the top right button
Load Default Filters. Then to apply these filters to the
NxtSE, click Apply Filters. After the filters have been
run, your session should now look like this:
SpliceWiz default filters - GUI
Why do we need to filter alternative splicing events?
Often, the gene annotations contain isoforms for all discovered splicing
events. Most annotated transcripts are not expressed, and their
inclusion in differential analysis complicates results including
adjusting for multiple testing. It is prudent to filter these out using
various approaches, akin to removing genes with low gene counts in
differential gene analysis. We suggest using the default filters which
work well for small experiments with sequencing depths at 100-million
paired-end reads.

Performing differential analysis
Using the edgeR wrapper ASE_edgeR(), perform
differential ASE analysis between conditions “A” and “B”:
# Requires edgeR to be installed:
require("edgeR")
res_edgeR <- ASE_edgeR(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A"
)Using the GUI
After running the previous sections (of the GUI instructions), click
Analysis and then
Differential Expression Analysis on the menu side bar. It
should look something like this:
Analysis - Differential Expression Analysis - GUI
To perform edgeR-based differential analysis, first ensure
Method is set to edgeR. Using the
Variable drop-down box, select condition.
Then, select the Nominator and Denominator
fields to B and A, respectively. Leave the
batch factor fields as (none). Then, click
Perform DE.
Once differential expression analysis has finished, your session
should look like below. The output is a DT-based data table equivalent
to the ASE_edgeR() function.
Example Differential Analysis using edgeR - GUI
NB: The interface allows users to choose to sort the results either by nominal or (multiple-testing) adjusted P values
NB2: There are 3 different ways Intron Retention events can be quantified and analysed - see “What are the different ways intron retention is measured?” below for further details.

What are the options for differential ASE analysis?
SpliceWiz provides wrappers to three established algorithms:
ASE_limmauseslimmato model isoform counts as log-normal distributions. Limma is probably the fastest method and is ideal for large datasets. Time series analysis is available for this mode.ASE_DESequsesDESeq2to model isoform counts as negative binomial distribution. This method is the most computationally expensive, but gives robust results. Time series analysis is also available for this modeASE_edgeRusesedgeRto model isoform counts as negative binomial distributions. SpliceWiz uses the quasi-likelihood method that deals better with variance at near-zero junction counts, resulting in reduced false positives.ASE_DoubleExpSequses the lesser-known CRAN packageDoubleExpSeq. This package uses the beta-binomial distribution to model isoform counts. The method is at least as fast aslimma, but for now it is restricted to analysis between two groups (i.e. batch correction is not implemented)
We recommend the following for differential analysis:
- For quick comparisons between two groups, where no batch factors are involved, we recommend DoubleExpSeq
- For large complex experiments where quick results are required for a preliminary or exploratory analysis, we recommend limma
- For final analysis where accuracy is paramount, we recommend edgeR or DESeq2
# Requires limma to be installed:
require("limma")
res_limma <- ASE_limma(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A"
)
# Requires DoubleExpSeq to be installed:
require("DoubleExpSeq")
res_DES <- ASE_DoubleExpSeq(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A"
)
# Requires DESeq2 to be installed:
require("DESeq2")
res_deseq <- ASE_DESeq(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A",
n_threads = 1
)
# Requires edgeR to be installed:
require("edgeR")
res_edgeR <- ASE_edgeR(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A"
)What are the different ways intron retention is measured?
Intron retention can be measured via two approaches.
The first (and preferred) approach is using IR-ratio. We presume that every intron is potentially retained (thus ignoring annotation). Given this results in many overlapping introns, SpliceWiz adjusts for this via the following:
- Where there are mutually-overlapping introns, the less abundant
intron is removed from the analysis. Abundance is estimated across the
entire dataset, and less-abundant overlapping introns are removed at the
makeSE()step. - IR-ratio measures included (intronic) abundance using an identical
approach to IRFinder, i.e., it calculates the trimmed mean of sequencing
depth across the intron, excluding annotated outliers (other exons,
intronic elements). Given we cannot assume whether the exact intron
corresponds to the major isoform, we estimate splicing abundance by
summing junction reads that share either exon cluster as the intron of
interest (
SpliceOvermethod in SpliceWiz). Alternately, users can choose to use IRFinder’sSpliceMaxmethod, summing junction reads that share either splice junction with the intron of interest. This choice is also made by the user at themakeSE()step.
At the differential analysis step, users can choose the following:
IRmode = "all"- all introns are potentially retained, use IR-ratio to quantify IR (EventType = "IR")IRmode = "annotated"- only annotated retained intron events are considered, but use IR-ratio to quantify IR (EventType = "IR")IRmode = "annotated_binary"- only annotated retained intron events are considered, use PSI to quantify IR - which considers the IR-transcript and the transcript isoform with the exactly-spliced intron as binary alternatives. Splicing of overlapping introns are not considered in PSI quantitation.
res_edgeR_allIntrons <- ASE_edgeR(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A",
IRmode = "all"
)
res_edgeR_annotatedIR <- ASE_edgeR(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A",
IRmode = "annotated"
)
res_edgeR_annotated_binaryIR <- ASE_edgeR(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A",
IRmode = "annotated_binary"
)Can I account for batch factors?
ASE_limma, ASE_edgeR, and
ASE_DESeq can accept up to 2 categories of batches from
which to normalize. For example, to normalize the analysis by the
batch category, one would run:
require("edgeR")
res_edgeR_batchnorm <- ASE_edgeR(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A",
batch1 = "batch"
)Can I do time series analysis?
Time series analysis can be performed using limma, edgeR, and
DESeq2.
For limma and edgeR, time series analysis is done using the
ASE_limma_timeseries() and
ASE_edgeR_timeseries() function. test_factor,
despite its name, should be a column in colData(se)
containing numerical values that represent time series data.
Note that these time series wrappers function requires the
splines package.
colData(se.filtered)$timevar <- rep(c(0,1,2), 2)
require("splines")
require("limma")
res_limma_cont <- ASE_limma_timeseries(
se = se.filtered,
test_factor = "timevar"
)
require("splines")
require("edgeR")
res_edgeR_cont <- ASE_edgeR_timeseries(
se = se.filtered,
test_factor = "timevar"
)For DESeq2, time series analysis is performed using the
ASE_DESeq() funcction. The key difference is that, for time
series analysis, simply do not specify the test_nom and
test_denom parameters. As long as the
test_factor contains numeric values, ASE_DESeq
will treat it as a continuous variable. See the following example:
colData(se.filtered)$timevar <- rep(c(0,1,2), 2)
require("DESeq2")
res_deseq_cont <- ASE_DESeq(
se = se.filtered,
test_factor = "timevar"
)Advanced GLM-based differential ASE analysis with edgeR
We have implemented wrapper functions enabling advanced users to perform differential ASE analysis by constructing their own design matrices. This allows users to evaluate effects of covariates in complex experimental models.
We will be building a separate vignette to illustrate the full functionality of these edgeR-based functions, but for now a quick example can be found in the relevant documentation, which can be viewed via:
Visualization
Volcano plots
Volcano plots show changes in PSI levels (log fold change, x axis) against statistical significance (-log10 p values, y axis):
library(ggplot2)
ggplot(res_edgeR,
aes(x = logFC, y = -log10(FDR))) +
geom_point() +
labs(title = "Differential analysis - B vs A",
x = "Log2-fold change", y = "FDR (-log10)")
Can I visualize significant events for each modality of alternative splicing events?
Yes. We can use ggplot2’s facet_wrap function
to separately plot volcanos for each modality of ASE. The type of ASE is
contained in the EventType column of the differential
results data frame.
ggplot(res_edgeR,
aes(x = logFC, y = -log10(FDR))) +
geom_point() + facet_wrap(vars(EventType)) +
labs(title = "Differential analysis - B vs A",
x = "Log2-fold change", y = "FDR (-log10)")
Using the GUI
After following the previous sections including differential analysis,
navigate to Display and then Volcano Plot.
Notice that there will be a message that says “No events found. Consider
relaxing some filters”.
This message occurs because our example dataset has no differential
events that surpass an adjusted P value of less than 0.05 (which is the
default filter setting). The SpliceWiz GUI avoids plotting all ASEs as
this will crowd the visualization. In this example, change the
Filter Events by to Nominal P value, and move
the P-value/FDR threshold all the way to the right. There
should now be a volcano plot but most events have near-zero significance
because the default y-axis setting is to
Plot adjusted P values. Switch this off to show the
following:
Volcano Plot - GUI
You can customize this volcano plot using the following controls:
- Use the filtering panel to adjust the number of events to show. Here, events can be filtered by Nominal or adjusted P values, or by top events. We can also filter by “highlighted events” which is useful for gene ontology analysis and heatmaps later. Events can also be filtered by the type of alternative splicing
- The volcano plot can be faceted by the type of alternative splicing.
- The y axis can show either nominal or adjusted P values (Benjamini Hochberg).
- If
NMD ModeisON, the horizontal axis represents whether splicing is shifted towards (positive values) or away from (negative values) a NMD substrate transcript - The plot can be exported as a pdf file (ggplot object)
- Clear settings
Also, on the (right hand side) main panel:
- This clears any selected events (selected events are highlighted in red)
- Toggle between using tools to select or deselect events
- Plotly interactive toolbox. Users can use the box-select (9a) or lasso- select (9b) to select (or de-select) one or more events of interest. Selected events are highlighted in other plots and non-selected points can be removed by selecting “highlighted events” in the event filter panel (1).
Scatter plots
Scatter plots are useful for showing splicing levels (percent-spliced-in, PSI) between two conditions. The results from differential analysis contains these values and can be plotted:
library(ggplot2)
ggplot(res_edgeR, aes(x = 100 * AvgPSI_B, y = 100 * AvgPSI_A)) +
geom_point() + xlim(0, 100) + ylim(0, 100) +
labs(title = "PSI values across conditions",
x = "PSI of condition B", y = "PSI of condition A")
#> Warning: Removed 1 row containing missing values or values outside the scale range
#> (`geom_point()`).
Using the GUI
After following the previous sections including differential analysis,
navigate to Display and then Scatter Plot.
After relaxing the event filters similar to the previous section, change
the Variable to condition,
X-axis condition to A and
Y-axis condition to B. A scatter plot should
be automatically generated as follows:
Scatter plot - GUI
You can customize the scatter plot using the following controls:
- Again, the filtering panel is available to filter the number of events by significance threshold, rank, or by highlighted events, as explained in the previous section (volcano plots - GUI)
Variablerefers to the annotation table column name- and (4) -
X-axisandY-axisdropdowns refer to the condition categories (that are used to contrast between two experimental conditions) - If
NMD ModeisON, the PSI values are altered such that they represent the inclusion values of the NMD substrate (instead of that of the “included” isoform) - The plot can be exported as a pdf file (ggplot object)
- Clear settings
As in the volcano plot, the scatter plot is interactive and points highlighted on this plot will stay highlighted in other plots.
- Clears all highlighted events
- Toggles between tools that select or de-select events
- Plotly interactive plot where users can use box or lasso select tools to select / de-select events.
Selecting ASEs of interest using the interactive plots (GUI)
SpliceWiz GUI generates plotly interactive figures. For volcano and
scatter plots, points of interest can be selected using the lasso or box
select tools. For example, we can select the top hits from the faceted
volcano plot as shown:
Volcano plot - selecting ASEs of interest via the GUI
These ASEs of interest will then be highlighted in other plots, for example scatter plot:
Scatter plot - highlighted ASE events
How do I generate average PSI values for many conditions?
SpliceWiz provides the makeMeanPSI() function that can
generate mean PSI values for each condition of a condition category. For
example, the below code will calculate the mean PSIs of each “batch” of
this example experiment:
Gene ontology (GO) analysis
Gene ontology analysis using the GUI
Our working example does not have enough genes to demonstrate a workable
gene ontology analysis. Instead, the following explains the controls
found in the Gene Ontology panel:
Gene ontology analysis
The controls are as follows:
- Again, the filtering panel is available to filter the number of events by significance threshold, rank, or by highlighted events, as explained in the previous sections. Filtered events are considered “enriched events” in the analysis.
- Type of gene ontology category - “Biological Function”, “Molecular Function” or “Cellular Compartment”
- Enrich for upregulated, downregulated events, or both
- Which set of genes to consider as background. Default is genes belonging to All ASE Events (as they contain introns). Alternatives are to either test for genes of ASEs of the specified modality (a popup select input box will appear, allowing users to select which modalities of ASE to derive background genes), or by all genes in the genome (NB this option will contain intronless genes which may bias the result).
- Gene ontology plots can be saved to PDF
- Gene ID’s of enriched genes (6a) or background genes (6b) can be exported to file, allowing users to repeat GO analysis using their own gene ontology enrichment tool of choice.
SpliceWiz has built-in gene ontology analysis. For now, only a limited number of species are supported for Ensembl gene ID’s. To see a list of supported organisms:

reference because there are only 7 genes in the example reference.
Nevertheless, the GO annotation is complete and relies on Ensembl
gene_ids for matching.
For simple gene over-representation analysis, we use the
goGenes function. As an example, to analyse for enriched
biological functions of the first 1000 genes in the reference:
allGenes <- sort(unique(ontology$gene_id))
exampleGeneID <- allGenes[1:1000]
exampleBkgdID <- allGenes
go_byGenes <- goGenes(
enrichedGenes = exampleGeneID,
universeGenes = exampleBkgdID,
ontologyRef = ontology
)To visualize the top gene ontology categories of the above analysis:
Of course, we wish to perform GO analysis on the top differential events in our analysis:
res_edgeR <- ASE_edgeR(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A"
)

To perform GO analysis using background genes from analysed ASEs:
Heatmaps
Heatmaps are useful for visualizing differential expression of individual samples, as well as potential patterns of expression.
First, obtain a matrix of PSI values:
# Create a matrix of values of the top 10 differentially expressed events:
mat <- makeMatrix(
se.filtered,
event_list = res_edgeR$EventName[1:10],
method = "PSI"
)
How does makeMatrix() work?
makeMatrix() provides a matrix of PSI values from the given
NxtSE object. The parameters event_list and
sample_list allows subsetting for ASEs and/or samples,
respectively.
The parameter method accepts 3 options:
"PSI": outputs raw PSI values"logit": outputs logit PSI values"Z-score": outputs Z-score transformed PSI values
Also, makeMatrix() facilitates exclusion of low
confidence PSI values. These can occur when counts of both isoforms are
too low. Setting the depth_threshold (default
10) will set samples with total isoform count below this
value to be converted to NA.
NA values are filtered
out. Setting the parameter na.percent.max (default
0.1) means any ASE with the proportion of NA
above this threshold will be removed from the final matrix.
Plot this matrix of values in a heatmap:
library(pheatmap)
anno_col_df <- as.data.frame(colData(se.filtered))
anno_col_df <- anno_col_df[, 1, drop=FALSE]
pheatmap(mat, annotation_col = anno_col_df)
Using the GUI
Navigate to Display, then Heatmap in the menu
side bar. After relaxing the event filters as per the prior sections, a
heatmap will be automatically generated:
Heatmap - GUI
The heatmap can be customized as follows:
- Again, the filtering panel is available to filter the number of events by significance threshold, rank, or by highlighted events, as explained in the previous sections. Highlighted events are particularly useful for heatmaps as users can (if they want) cherry-pick events of interest
- After above filtering, an additional filter by gene ontology category can be performed. GO analysis must first be performed, and the top enriched categories are listed here
- Samples can be annotated by one or more annotation categories
- Samples can be sorted by the chosen annotation category
- If (4) is selected, whether the sort order should be ascendeng or descending
- The maximum number of rows of the heatmap to display
- Whether the heatmap values are raw PSI, logit-transformed PSI, or Z-score transformed values
- Users can customize their heatmap color palettes from this list
- A static plot (using the pheatmap R package) will be saved to PDF
SpliceWiz Coverage Plots
Coverage plots visualize RNA-seq coverage in individual samples.
SpliceWiz uses its coverage normalization algorithm to visualize group
differences in PSIs.
What are SpliceWiz coverage plots and how are they generated?
SpliceWiz produces RNA-seq coverage plots of analysed samples. Coverage
data is compiled simultaneous to the IR and junction quantitation
performed by processBAM(). This data is saved in “COV”
files, which is a BGZF compressed and indexed file. COV files show
compression and performance gains over BigWig files.
Coverage plots of individual samples
First, lets obtain a list of differential events with delta PSI > 5%:
res_edgeR <- ASE_edgeR(
se = se.filtered,
test_factor = "condition",
test_nom = "B",
test_denom = "A"
)
#> Oct 29 19:46:50 Performing edgeR contrast for included / excluded counts separately
#> Oct 29 19:46:51 Performing edgeR contrast for included / excluded counts together
res_edgeR.filtered <- res_edgeR[res_edgeR$abs_deltaPSI > 0.05,]
res_edgeR.filtered$EventName[1]
#> [1] "NSUN5/ENST00000252594_Intron2/clean"We can see here the top differential event belongs to NSUN5. The first step to plotting this event is to create a data object that contains the requisite data for the gene NSUN5:
This step retrieves all coverage and junction data for NSUN5 (and
surrounding genes).
Next, we need to create event-specific data for the IR event in NSUN5 intron 2.
This step normalizes the coverage and junction data from the
viewpoint of NSUN5 intron 2.
The final step is to generate the plot:
plotView(
plotObj,
centerByEvent = TRUE, # whether the plot should be centered at the `Event`
trackList = list(1,2,3,4,5,6),
plotJunctions = TRUE
)
This plots all 6 individual coverage plots, each in its own
track.
Why are the tracks referred to using numbers
In the covPlotObject which is returned by the above function, each
“track” is a sample. These can be viewed using the tracks()
function:
For convenience, users have the option of referring to tracks by their actual names, or by numbers. So, in the above example, the two parameters below are equivalent:
trackList = list(1,2)- `trackList = list(“02H003”, “02H025”)
Normalized Coverage plots of individual samples
To plot “normalized” coverage plots, where coverage is normalized to
transcript depth (i.e. sum of all transcripts = 1), set
normalizeCoverage = TRUE. We can also include multiple
samples in each trace, so lets stack all samples in the same condition
in the same trace:
plotView(
plotObj,
centerByEvent = TRUE,
trackList = list(c(1,2,3), c(4,5,6)),
# Each list element contains a vector of track id's
normalizeCoverage = TRUE
)
NB: junction (sashimi) arcs are not plotted in tracks with more than 1 trace (to avoid cluttering)
Group Coverage plots
To plot group coverage plots, first we need to generate a new
covPlotObject. This is because the previous
covPlotObject was generated on the basis of each track
being an individual sample. To generate a plot object where each track
represents a condition:
plotObj_group <- getPlotObject(
dataObj,
Event = res_edgeR.filtered$EventName[1],
condition = "condition",
tracks = c("A", "B")
)
# NB:
# when `condition` is not specified, tracks are assumed to be the same samples
# as that of the covDataObject
# when `condition` is specified, tracks must refer to the condition categories
# that are desired for the final plotNote that there are several scenarios where a new covPlotObject is required:
- When plotting normalized coverages using a different normalization ASE,
- When plotting by a different condition or different tracks,
- When plotting on a different strand (default is
*- unstranded)
To generate the group coverage plot, with the two conditions on the same track:
Coverage plots using exon windows
Sometimes, we are interested in the differential coverage of exons but not of the intervening introns. Given introns are often much longer than exons, it is useful to plot by the exons of interest.
For example, to plot the skipped casette exon in TRA2B:
dataObj <- getCoverageData(se, Gene = "TRA2B", tracks = colnames(se))
plotObj <- getPlotObject(
dataObj,
Event = "SE:TRA2B-206-exon2;TRA2B-205-int1",
condition = "condition", tracks = c("A", "B")
)
plotView(
plotObj,
centerByEvent = TRUE,
trackList = list(c(1,2)),
filterByEventTranscripts = TRUE
)
NB: setting filterByEventTranscripts = TRUE means only
transcripts involved in the specified splicing event are plotted in the
annotation
Note that the involved exons are in only a small area of the coverage plot. To zoom in on the exons, we first have to plot an “exon view” so the exons are labelled, and at the same time return their coordinates:
gr <- plotView(
plotObj,
centerByEvent = TRUE,
trackList = list(c(1,2)),
filterByEventTranscripts = TRUE,
showExonRanges = TRUE
)
By setting the parameter showExonRanges = TRUE, the
plotView function shows a plot with exons and their names
in the annotation track, and returns a GRanges object, with ranges named
by their corresponding exon names:
names(gr)
#> [1] "TRA2B-205-E3" "TRA2B-206-E4" "TRA2B-206-E3" "TRA2B-206-E2" "TRA2B-206-E1"
#> [6] "TRA2B-205-E2" "TRA2B-213-E2" "TRA2B-213-E1" "TRA2B-205-E1"We can see in the above figure that he exons of interest are
c("TRA2B-206-E1", "TRA2B-206-E2", "TRA2B-206-E3"). To plot
these in an “exons view” coverage plot:
plotView(
plotObj,
centerByEvent = TRUE,
trackList = list(c(1,2)),
filterByEventTranscripts = TRUE,
plotRanges = gr[c("TRA2B-206-E1", "TRA2B-206-E2", "TRA2B-206-E3")]
)
Using the GUI
The main coverage plot interface is as follows
Coverage Plots Main Panel - GUI
The top bar contains controls to locate the genomic loci of interest:
- Genes - locate by the specified gene
- Events - locate by the specified alternate splicing event. The list of events can be modified by the right-hand controls in the top bar
- Coordinates - locate by the specified chromosome and start/end coordinate
- Zoom in or out (each step by a factor of 3)
- Strand - view coverage by strand-specific (+/-) or non-specific (*) modes
- Select events either by all events in differential analysis (which can be filtered using the html-table column filters), user-highlighted events (using volcano/scatter plots), or by gene ontology category. If using gene-ontology category, an extra drop-down box will appear allowing users to specify from the top gene ontology categories from prior GO analysis
- Limit the number of events displayed in the Event drop-down box (2)
In the plot control panel on the left hand side of the main plot area:
- Select which alternative splicing event that should be normalized against. This is critical when plotting normalized coverages (14) or plotting by condition (9)
- Select whether to plot by individual samples, or specify the condition to plot group-plots. See the next section for condition-specific controls.
- The track list table allows users to specify track ID’s for one or more of the specified controls. The left hand column displays available sample names (if plotting by individual samples), or condition categories (if a condition is specified)
- Interactive plots can be slow to render because of too many data points. Resolution (the number of data points across the main display) can be controlled using this slider.
- For group plots, variance of each group can be displayed either as standard deviation (SD), standard error of the mean (SEM), 95% confidence interval (95% CI) or none.
- Whether junction (sashimi) arcs should be plotted. Note that junction arcs will be disabled if there are multiple traces on the same track
- When plotting individual samples, whether raw or normalized coverages should be displayed. Junction counts will also be normalized (they are automatically normalized in group coverage plots)
- Whether to display isoforms belonging to the included / excluded isoform described in the selected normalizing alternative splicing event
- Whether transcripts should be condensed by gene. This is useful if there are too many transcripts cluttering the display.
- If selected, brings up a transcript table where users can select 1 or more transcripts to display in the annotation track.
- If selected, converts the annotation track into an exons display track with named exons. A table will pop up allowing users to select 2 or more exon ranges. Selecting these exons will generate a static exons-only coverage plot.
The main plot (19) is a plotly-based interactive plot. Users can zoom in to a genomic loci of interest using the zoom tool.
There are several options that appear if a specific condition is set:
Group Coverage Plots - GUI
- Note that the track list table now shows condition categories instead of names of samples
- Difference of normalized coverage between conditions can be objectively measured. Users have the option to use the Student’s T-test to measure difference in normalized coverage between replicates of a pair of conditions
- Two drop-down boxes allowing users to select a pair of conditions to assess difference in normalized coverage
As mentioned, when the “Exon Plot mode” is selected, an exons table is displayed where users can select one or more exon ranges can be selected, as shown below:
Generating Exon Coverage (Static) Plots - GUI
Selecting 2 or more exon ranges will trigger (after a 3 second delay) a static exon-window coverage plot to be generated.
Note that at the bottom of the left hand panel, users can save the interactive (top) plot, or the static exon-window coverage (bottom) plot to PDF as ggplot- based figures.
