RomanovBrainData | R Documentation |
Obtain the mouse brain single-cell RNA-seq dataset from Romanov et al. (2017).
RomanovBrainData(ensembl = FALSE, location = TRUE, legacy = FALSE)
ensembl |
Logical scalar indicating whether the output row names should contain Ensembl identifiers. |
location |
Logical scalar indicating whether genomic coordinates should be returned. |
legacy |
Logical scalar indicating whether to pull data from ExperimentHub. By default, we use data from the gypsum backend. |
Column metadata is provided in the same form as supplied in GSE74672. This contains information such as the reporter gene expressed in each cell, the mouse line, dissection type and so on.
Counts for ERCC spike-ins are stored in the "ERCC"
entry of the altExps
.
Note that some of the spike-in rows have NA
observations for some (but not all) cells.
If ensembl=TRUE
, the gene symbols 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
of the output.
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/romanov-brain
.
A SingleCellExperiment object with a single matrix of UMI counts.
