Description

Obtain the Mair PBMC targeted CITE-seq data from Mair et al. (2020).

Usage

1
MairPBMCData(mode = c("rna", "adt"), ensembl = FALSE, location = TRUE)

Arguments

mode

Character vector specifying whether to return either or both the RNA and ADT counts.

ensembl

Logical scalar indicating whether the output row names should contain Ensembl identifiers.

location

Logical scalar indicating whether genomic coordinates should be returned.

Details

Column metadata contains the donor identity and cartridge of origin. Some libraries may also be classified as multiplets or have undeterminate origins after hash tag debarcoding.

If ensembl=TRUE, the gene symbols in the RNA data are converted to Ensembl IDs in the row names of the output object. Rows with missing Ensembl IDs are discarded, and only the first occurrence of duplicated IDs is retained.

If location=TRUE, the coordinates of the Ensembl gene models are stored in the rowRanges for the RNA data. Note that this is only performed if ensembl=TRUE.

All data are downloaded from ExperimentHub and cached for local re-use. Specific resources can be retrieved by searching for scRNAseq/mair-pbmc.

Value

A SingleCellExperiment object with a single matrix of UMI counts corresponding to the first mode, with an optional alternative Experiment if there is a second mode.
