library(SingleCellMultiModal)ECCITE-seq data are an evolution of the CITE-seq data (see also CITE-seq vignette for more details) by extending the CITE-seq original data types with a third one always extracted from the same cell. Indeed, in addition to the CITE-seq providing scRNA-seq and antibody-derived tags (ADT), it provides around ten Hashtagged Oligo (HTO). In particular this dataset is provided by Mimitou et al. (2019).
The user can see the available dataset by using the default options through the CITE-seq function.

CTCL stands for cutaneous T-cell lymphoma while CTRL for control.
For example, if we want only the CTCL samples, we can run:

They can be accessed with the metadata accessors which, in this case returns a named list of data.frames.

names(sgRNAs)## [1] "CTCL_TCRab" "CTCL_TCRgd" "CTRL_TCRab" "CTRL_TCRgd"There are four different sgRNAs datasets, one per each condition and family receptors combination.
TCR stands for T-Cell Receptor, while a,b,g,d stand for alpha, beta, gamma and delta respectively.

in the [SingleCellExperiment vignette][1] or [CiteFuse Vignette][2] where the
SingleCellExperiment object is used for CITE-seq data,
we provide a function for the conversion of our CITE-seq MultiAssayExperiment
object into a SingleCellExperiment object with scRNA-seq data as counts and
scADT data as altExps.
