R/runBatchCorrection.R
runSCMerge.Rd
The scMerge method leverages factor analysis, stably expressed genes (SEGs) and (pseudo-) replicates to remove unwanted variations and merge multiple scRNA-Seq data.
runSCMerge( inSCE, useAssay = "logcounts", batch = "batch", assayName = "scMerge", seg = NULL, kmeansK = NULL, cellType = "cell_type", nCores = 1L )
inSCE | SingleCellExperiment inherited object. Required. |
---|---|
useAssay | A single character indicating the name of the assay requiring
batch correction. Default |
batch | A single character indicating a field in
|
assayName | A single characeter. The name for the corrected assay. Will
be saved to |
seg | A vector of gene names or indices that specifies SEG (Stably
Expressed Genes) set as negative control. Pre-defined dataset with human and
mouse SEG lists is available to user by running |
kmeansK | An integer vector. Indicating the kmeans' K-value for each
batch (i.e. how many subclusters in each batch should exist), in order to
construct pseudo-replicates. The length of codekmeansK needs to be the same
as the number of batches. Default |
cellType | A single character. A string indicating a field in
|
nCores | An integer. The number of cores of processors to allocate for
the task. Default |
The input SingleCellExperiment object with
assay(inSCE, assayName)
updated.
