1 Overview
SBGNview is a tool set for pathway based data visalization, integration and analysis. SBGNview is similar and complementary to the widely used Pathview(Luo and Brouwer 2013), with the following key features:
Pathway definition by the widely adopted Systems Biology Graphical Notation (SBGN);
Supports multiple major pathway databases beyond KEGG (Reactome, MetaCyc, SMPDB, PANTHER, METACROP etc) and user defined pathways;
Covers 5,200 reference pathways and over 3,000 species by default;
Extensive graphics controls, including glyph and edge attributes, graph layout and sub-pathway highlight;
SBGN pathway data manipulation, processing, extraction and analysis.

Please see the Quick Start tutorial for installation instructions and quick start examples.
4 Getting started
SBGNview is the main function of the package. It takes two major types of inputs: user data (gene and/or compound data) and SBGN pathway data (pathway IDs or SBGN-ML files). SBGNview parses the SBGN pathway data, extracts glyph (node) and arc (edge) data from SBGN-ML file, maps and integrates the user data to the glyphs and renders the SBGN graph in SVG formatwith mapped data as pseudo-colors. Currently it maps gene/protein omics data to “macromolecule” glyphs and maps compound omics data to “simple chemical” glyphs. The SBGNview function returns a SBGNview object, which contains data to recreate the rendered SBGN graph or further modified it. Please see the documentation of function SBGNview for more details.

SBGN pathways are defined in a special XML format (SBGN-ML file). SBGN-ML files describe the pathway elements (molecules and their reactions) and the graph layout (positions and appearances of the pathway elements). There are two major data types ement in SBGN-ML files: 1. node data (in tag “glyph”), such as node location, width, hight and node class (macromolecule, simple chemical etc.). 2. edge data (in tag “arc”), such as arc class, start node and end node. For more details, see: https://github.com/sbgn/sbgn/wiki/SBGN_ML
4.3.1 Two tiers of support and two scenarios with SBGN based pathways
SBGNview provides two tiers of support for SBGN based pathway data, which corresponds to the two common SBGNview scenarios:
Scenarios 1 or Tier 1{#ourCollection}, direct and deep support to a core collection of pathway data from 5 major pathway databases including Reactome, SMPDB, PANTHER, MetaCyc and MetaCrop, or using SBGNview’s pathway collection. Each of these databases covers up to thousands of reference pathways and species (Table 1). SBGNview provides diagram optimization and ID mapping on these pathway databases. In other words, ve prepared a full collection of high quality sbgn pathways from these databases, which can be directly used in data analysis. The pathway data in SBGN-ML format are stored in data sbgn.xmls (included in package SBGNview.data), which are effectively indexed/accessed by SBGNview pathway IDs. We’ve also generated ID mapping between SBGN-ML glyph IDs and common molecule IDs, so that user data can be easily mapped to these pathways.
Scenarios 2 or Tier 2, indirect support to raw SBGN pathway data from pathway databases, collections and users’ custom pathway data. Many major pathway databases provide SBGN-ML files, including Pathway Commons, Reactome and MetaCrop. Their data can be downloaded and directly used by SBGNview. Other databases (e.g. PANTHER and BioCyc) use SBML or BioPAX formats, which can be converted to SBGN-ML format using third party tools. Note Pathway Commons collect pathways from Reactome, PANTHER, SMPDB and other primary databases. These data can be used in SBGNview, except diagrams may not be optimized for data visualization, and users need to provided ID mapping or make sure the glyph IDs are commonly use molecule IDs.
Note the core collection of pathway databases with tier 1 support includes thousands of pathways and species, which should cover most of the users needs in pathway analysis and data visualization. We are taking the first the default route, i.e. to use the SBGNview’s core collection.
4.3.1.1 Load SBGNview’s SBGN-ML pathway data collection
Because a large amount of pathway data is loaded into R, this step can take up to several second.
data("sbgn.xmls")4.3.1.2 Information about the SBGN-ML pathway data collection
We can check the information of collected pathways using pathways.info and number of pathways collected using pathways.stats.

SBGNview can search for pathways by keyword and automatically download SBGN-ML files.
pathways <- findPathways(c("bile acid","bile salt"))
head(pathways)
pathways.local.file <- downloadSbgnFile(pathways$pathway.id[1:3])
pathways.local.fileBy default findPathways searches for keywords in pathway names. It can also search by different ID types
pathways <- findPathways(c("tp53","Trp53"),keyword.type = "SYMBOL")
head(pathways)
pathways <- findPathways(c("K04451","K10136"),keyword.type = "KO")
head(pathways)4.3.1.4 Different layout for the same pathway
Researchers may have different tastes for a “good looking” layout. We have created different layouts for each pathway. User can download them from pre-generated SBGN-ML files and try.
4.3.2 Custom SBGN-ML files
USers can also define their own pathways and create custom SBGN-ML files from scratch. Several tools like Newt editor can let the user draw a pathway diagram and save it as SBGN-ML file. The tools may also able to generate a primitive pathway layout. But these layouts are usually not desirable for data visualization with too many node-node overlaps and edge-node crossings. Therefore, we recommend the users to stick to SBGNview core collection.
5 Basic visualization
SBGNview can visualize a range of omics data, including both gene (or transcript, protein, enzyme) data and compound (or metabolite, chemical, small molecules) data.
5.1 Visualize gene data
Gene/protein related data will be mapped to “macromolecule” nodes or glyphs on SBGN maps. Most of online databases or resources have their unique glyph ID types and it is likely different from the ID type in the gene data. We often need to map the omics IDs to the node IDs in the SBGN-ML file. In the quick start example (“Adrenaline and noradrenaline biosynthesis” pathway), the SBGN-ML file uses pathwayCommons IDs for gene/protein nodes, whereas the omics dataset uses Entrez gene IDs. The function SBGNview can automatically map common ID types such as ENTREZ, UniProt etc. to nodes in our pre-generated SBGN-ML files as shown in the quick start example. We can also do it manually using function changeDataId, which is called by SBGNview internally to do ID mapping. Supported ID type pairs can be found in data(mapped.ids). changeDataId uses pre-generated mapping tables or pathview to do the mapping. If the input-output ID type pair is not in data(mapped.ids) or can’t be mapped by SBGNview automatically, user needs to provide the mapping table explicitly using the “id.mapping.table” argument.
Firt, load the preprocessed demo gene data.
data("gse16873.d")
head(gse16873.d)Let’s change the IDs in the gene data manually as an demo.
# select a subset of data for later use
gse16873 <- gse16873.d[,1:3]
# gene data to demonstrate ID convertion
gene.data <- gse16873
head(gene.data[,1:2])## DCIS_1 DCIS_2

mol.type = "gene",
sum.method = "sum")When multiple genes are mapped to the same glyph ID, we use the sum of their values (sum.method = “sum”).

SBGNview.obj <- SBGNview(gene.data = gene.data,
input.sbgn = "P00001",
output.file = "test_output",
gene.id.type = "pathwayCommons",
output.formats = c("png", "pdf", "ps"))
SBGNview.objSBGNview will always generate a .svg file. Other formats can be added also. In this example, three additional files (pdf, ps, png) will be created in the same folder.
Figure 5.1: Visualization of gene expression data.
5.2 Visualize compound data
Chemical compound data will be mapped to “simple chemical” nodes on a SBGN map.
Here we simulate a compound dataset.
cpd.data <- sim.mol.data(mol.type = "cpd",
id.type = "KEGG COMPOUND accession",
nmol = 50000,
nexp = 2)
head(cpd.data)Here for demo purpose, we change the KEGG compound IDs to pathwayCommons compound IDs. Although SBGNview can do this automatically, see Visualize both gene data and compound data.
cpd.data1 <- changeDataId(data.input.id = cpd.data,
input.type = "kegg",
output.type = "pathwayCommons",
mol.type = "cpd",
sum.method = "sum")
head(cpd.data1)Now we run SBGNview, the main function to map and render compound data on SBGN map.
SBGNview.obj <- SBGNview(cpd.data = cpd.data1,
input.sbgn = "P00001",
output.file = "test_output.cpd",
cpd.id.type = "pathwayCommons",
output.formats = c("png", "pdf", "ps"))
SBGNview.obj
Figure 5.2: Visualization of compound abundance data.
5.3 Visualize both gene data and compound data
Now we can visualize both gene and compound data. In this example, we use the original gene expression data with “ENTREZ” IDs to show SBGNview’s automatic ID mapping ability.
SBGNview.obj <- SBGNview(gene.data = gse16873,
cpd.data = cpd.data,
input.sbgn = "P00001",
output.file = "test_output.gene.compound",
gene.id.type = "entrez",
cpd.id.type = "kegg",
output.formats = c("svg"))
SBGNview.obj
Figure 5.3: Visualization of both gene expression and compound abundance data.
6 Work with SBGNview object
SBGNview operates in a way similar to ggplot2:
The main function SBGNview returns a S3 class SBGNview object (similar to the ggplot object “p” returned by function ggplot in ggplot2), which contains information needed to render SBGN graph, and output file name. Make sure the input SBGN-ML files are available in the folder. The input.sbgn parameters takes in names of local SBGN files or pathway IDs and sbgn.dir specifies the path to local files. Printing this object will render the graph and write output image files. SBGNview object can be further modified by several functions to highlight nodes/edges/paths (e.g. SBGNview.obj + highlightNodes(), similar to p + geom_boxplot() in ggplot2).
- These operations will generate image files
The following command
SBGNview(...) + highlightNodes(...)orSBGNview.obj + highlightNodes(...)will return a SBGNview object to R console. The returned object is executed as a top-level R expression, thus will be implicitly printed using theprint.SBGNviewfunction in SBGNview package. For more details, please see the documentation forprint.SBGNviewfunction.Running
SBGNview.objin the R console will implicitly print the object whileprint(SBGNview.obj)will explicitly print the object usingprint.SBGNviewfunction.
- These commands will NOT generate plot files:
SBGNview.obj = SBGNview(...) + highlightNodes(...). The assign operation “=” will make the returned object invisible therefore it will not be printed.
6.1 Structure of SBGNview object
The SBGNview object is a S3 object defined as a list structure containing ‘data’ and ‘output.file’ and ‘output.formats’ elements. The object is created by the SBGNview S3 class defined within the package. The ‘data’ element of the object is a list containing information for all input SBGN pathways. Each element in ‘data’ is a list holding information of a single SBGN pathway. The information includes parsed glyphs, parsed arcs and other parameters to control graph features passed into SBGNview function. The ‘output.file’ element of the object is a string specified for the ‘output.file’ parameter in SBGNview function. The output file name can be modified using outputFile. The output formats can be updated by assigning a character vector of supported file formats by SBGNview function. The code chucks below demonstrate how you can access glyphs and arcs information of a SBGNview object as well as changing output file name and output formats.
6.2 Extract glyphs and arcs infromation from SBGNview object
pathway.1.data <- SBGNview.obj$data[[1]]
names(pathway.1.data)
glyphs <- pathway.1.data$glyphs.list
arcs <- pathway.1.data$arcs.list
str(glyphs[[1]])
str(arcs[[1]])
global.pars <- pathway.1.data$global.parameters.list
names(global.pars)6.3 Modify SBGNview object directly
For each pathway in SBGNview object, the ‘global.parameters.list’ element seen above contains the default graphical parameters controlling the plotting of allelements (glyphs and arcs) of the pathway. We can modify these default parameters manually when needed. Most graphical parameters or features of individual glyphs or arcs can be controlled manually by directly modifying the SBGNview object too. For instance, we can modify different slots of glyphs[[1]] or arcs[[1]] in the code chunk above. Please make sure to read the documentation of SBGNview S3 class in the Value section fo SBGNview function.
6.4 Change output file name and format of SBGNview objects
We can change the name of the output file using built-in function outputFile:
outputFile(SBGNview.obj)
outputFile(SBGNview.obj) <- "test.change.output.file"
outputFile(SBGNview.obj)
SBGNview.obj
outputFile(SBGNview.obj) <- "test.print"
outputFile(SBGNview.obj)
print(SBGNview.obj)We can update or change the output file formats of a SBGNview object. Supported output file formats are any combination of “png”, “pdf”, and “ps”. If an empty vector of output file formats are provided, only the SVG file format will be written to current working directory.
print(SBGNview.obj$output.formats)
SBGNview.obj$output.formats <- c("png", "pdf")7 Updating & modifying graphs
It is useful to highlight interesting nodes, edges or paths in a pathway map. One way is to modify the SBGNview object directly as we’ve seen above. The more systematic way is to use the build-in highlight functions. In other words, the SBGNview object can be further modified by concatenating it with modification or highlight functions using binary operator + (see quick start for example).
7.1 Hightlight nodes
7.1.1 Highlight all nodes
# Here we set argument "node.set" to select all nodes to be highlighted
highlight.all.nodes.sbgn.obj <- SBGNview.obj + highlightNodes(node.set = "all",
stroke.width = 4,
stroke.color = "green")
outputFile(highlight.all.nodes.sbgn.obj) <- "highlight.all.nodes"
print(highlight.all.nodes.sbgn.obj)
Figure 7.1: Highlight all nodes.
7.1.2 Highlight nodes by class
# Here we set argument "select.glyph.class" to select and highlight macromolecule nodes
highlight.macromolecule.sbgn.obj <- SBGNview.obj +
highlightNodes(select.glyph.class = "macromolecule",
stroke.width = 4,
stroke.color = "green")
outputFile(highlight.macromolecule.sbgn.obj) <- "highlight.macromolecule"
print(highlight.macromolecule.sbgn.obj)
Figure 7.2: Highlight macromolecule nodes.
7.1.3 Show node IDs instead of node labels
# Here we set argument "show.glyph.id" to display node ID instead of the original label
highlight.all.nodes.sbgn.obj <- SBGNview.obj + highlightNodes(node.set = "(+-)-epinephrine",
stroke.width = 4,
stroke.color = "green",
show.glyph.id = TRUE,
label.font.size = 10)
outputFile(highlight.all.nodes.sbgn.obj) = "highlight.all.id.nodes"
print(highlight.all.nodes.sbgn.obj)
Figure 7.3: Highlight nodes using node IDs.
7.2 Adjust node labels.
7.2.1 Label position, font size, color, change labels
The function highlightNodes also can be used to adjust labels. In this example, we move the label horizontally and vertically, change their color and font size.
# Node labels can be customized by a named vector. The names of the vector are the IDs assigned to argument "node.set". Values of the vector are the new labels for display.
my.labels <- c("Tyr","epinephrine")
names(my.labels) <- c("tyrosine", "(+-)-epinephrine")
SBGNview.obj.adjust.label <- SBGNview.obj +
highlightNodes(node.set = c("tyrosine", "(+-)-epinephrine"),
stroke.width = 4,
stroke.color = "green",
label.x.shift = 0,
# Labels are moved up a little bit
label.y.shift = -20,
label.color = "red",
label.font.size = 30,
label.spliting.string = "",
labels = my.labels)
outputFile(SBGNview.obj.adjust.label) <- "adjust.label"
print(SBGNview.obj.adjust.label)
Figure 7.4: Modify node labels.
7.2.2 Label text wrapping into multiple lines
Some nodes may have long labels thus overlap with surrounding graph elements. In this case we can set the parameter label.spliting.string to “any” so the label will be wrapped in multiple lines that fit the width of the node.
SBGNview.obj.change.label.wrapping <- SBGNview.obj +
highlightNodes(node.set = c("tyrosine", "(+-)-epinephrine"),
stroke.width = 4,
stroke.color = "green",
show.glyph.id = TRUE,
label.x.shift = 10,
label.y.shift = 20,
label.color = "red",
label.font.size = 10,
label.spliting.string = "any")
outputFile(SBGNview.obj.change.label.wrapping) = "change.label.wrapping"
print(SBGNview.obj.change.label.wrapping)
Figure 7.5: Change how labels are wrapped.
7.3 When one input ID maps to multiple nodes
In the example above, we saw that one input ID (e.g. “(+-)-epinephrine”) can be mapped to multiple nodes in the graph. If we just want to focus on several particular ones, we can use function highlightNodes to find the node IDs, which is unique to each node:
# When "label.spliting.string" is set to a string that is not in the label (including an empty string ""), the label will not be wrapped into multiple lines.
test.show.glyph.id <- SBGNview.obj + highlightNodes(node.set = c("tyrosine", "(+-)-epinephrine"),
stroke.width = 4,
stroke.color = "green",
show.glyph.id = TRUE,
label.x.shift = 10,
label.y.shift = 20,
label.color = "red",
label.font.size = 10,
label.spliting.string = "")
outputFile(test.show.glyph.id) <- "test.show.glyph.id"
print(test.show.glyph.id)
Figure 7.6: Show node IDs of mapped nodes.
We can find the mapping between input IDs and node IDs:
input.pathways <- findPathways("Adrenaline and noradrenaline biosynthesis")
input.pathway.ids <- input.pathways$pathway.id
mapping <- changeIds(input.ids = c("tyrosine", "(+-)-epinephrine"),
input.type = "compound.name",
output.type = "pathwayCommons",
mol.type = "cpd",
limit.to.pathways = input.pathway.ids[1])mapping## $tyrosine

## [3] "SmallMolecule_a25ed355cc2a6a0800babeb708e2cba4"7.4 Highlight arcs and paths
In addition to nodes and their attributes, we may also highlight arcs and paths and modify their attributes. The Quick Start vignette has one example on highlighting nodes, arcs and paths together.
Here, we can pick two nodes to highlight and find a shortest path between them.
outputFile(SBGNview.obj) <- "highlight.by.node.id"SBGNview.obj + highlightNodes(node.set = c("tyrosine", "(+-)-epinephrine"),
stroke.width = 4,
stroke.color = "red") +
highlightPath(from.node = "SmallMolecule_96737c854fd379b17cb3b7715570b733",

7.5 Different layouts for the same pathway
If the default layout is not ideal, users have two options:
Modify the layout manually using tools like newt editor
Download our pre-generated SBGN-ML files SBGN-ML files with a different layout. Currently there limited pathways with multiple layout. More will be added in the future.
A new layout for P00001 (“Adrenaline and noradrenaline biosynthesis”) pathway ID is included as part of the SBGNview package.
new.layout.file.path <- paste(path.package("SBGNview"), "extdata", sep = "/")
SBGNview(gene.data = gse16873,
gene.id.type = "entrez",
input.sbgn = "P00001.new.layout.sbgn",
sbgn.dir = new.layout.file.path,
sbgn.gene.id.type = "pathwayCommons",
output.file = "test.different.layout",
output.formats = c("svg"))
Figure 7.8: Graph with different layout.
7.6 SVG Editing Tool
SBGNview provides extensive graphical control options for adjusting glyph/arc attributes such as line color/width and text size/color/wrapping/positioning. The SBGNview main function outputs SVG file format by default and other (png, pdf, ps) specified file formats. There might be cases where you would like to adjust specific graphical details more easily. In such cases, Inkscape can be used to modify the generated SVG file and save/export the SVG to other file formats provided by Inkscape.
8 ID mapping
SBGNview can automatically map common ID types to SBGN-ML glyphs in our SBGNview pathway collection. Supported ID types can be accessed as follow:
data("mapped.ids")8.1 Map between two types of IDs
Besides changeDataId which changes ID for omics data, SBGNview provides functions to map between different types IDs:
mapping <- changeIds(input.ids = c("tyrosine", "(+-)-epinephrine"),
