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.

## CD11c 3The dataset has two different conditions (CTCL and CTRL) which
samples can be identified with the colData accessor.
CTCL stands for cutaneous T-cell lymphoma while CTRL for control.
For example, if we want only the CTCL samples, we can run:
## A MultiAssayExperiment object of 3 listed
## experiments with user-defined names and respective classes.
## Containing an ExperimentList class object of length 3:
## [1] scADT: dgCMatrix with 52 rows and 6500 columns

## Functionality:
## experiments() - obtain the ExperimentList instance
## colData() - the primary/phenotype DataFrame
## sampleMap() - the sample coordination DataFrame
## `$`, `[`, `[[` - extract colData columns, subset, or experiment
## *Format() - convert into a long or wide DataFrame
## assays() - convert ExperimentList to a SimpleList of matrices
## exportClass() - save data to flat filesAnd if you’re interested into the common samples across all the
modalities you can use the complete.cases funtion.

## [2] scHTO: dgCMatrix with 7 rows and 4190 columns
## [3] scRNA: dgCMatrix with 33538 rows and 4190 columns

## assays() - convert ExperimentList to a SimpleList of matrices
## exportClass() - save data to flat filesThe CRISPR perturbed scRNAs data are stored in a different spot to keep their original long format.
They can be accessed with the metadata accessors which,
in this case returns a named list of
data.frames.
## [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.
To look into the TCRab, simply run:

[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.
