Webrow and the j-th column of the matrix tells how many reads have been mapped to gene iin sample j. Analogously, for other types of assays, the rows of the matrix might correspond e.g. to binding regions (with ChIP-Seq) or peptide sequences (with quantitative mass spectrometry). The count values must be raw counts of sequencing reads. WebRemember that Seurat has some specific functions to deal with different scRNA technologies, but let’s say that the only data that you have is a gene expression matrix.
