Merger: Merge expression matrices

In jbergenstrahle/STUtility: Analysis and visualization of Spatial Transcriptomics data

Merge expression matrices

Description

This function takes a list of expression matrices as input with ST spots in columns and genes in rows. All expression matrices will be merged into one matrix where all genes that are present in any of the expression matrices will be included. If a there are no counts available for a gene in one or more of the expression matrices, the counts for that gene will be set to 0 in those expression matrices. By default, a unique number will be prefixed to the headers of each expression matrix.

Usage

Merger(exp.list, delim = "x", labels = NULL, sparse.matrix.fmt = F)

Arguments

exp.list	list of expression matrices
delim	delimiter used to separate coordinates in expression matrix headers
labels	labels to use as suffix for the headers of each expression matrix
sparse.matrix.fmt	return mergedexpression matrix in dgCMatrix format to save memory

Value

merged expression matrix
