WebGenerating a Gene Expression Matrix. Most analyses have two stages: data reduction and biological analysis. Statistical analyses of scRNA-seq data take as their starting point an expression matrix, where each row represents a gene and each column represents a sample (in scRNAseq a cell).Each entry in the matrix represents the number of reads (expression … WebAll scRNASeq protocols are sequenced with paired-end sequencing. Barcode sequences may occur in one or both reads depending on the protocol employed. However, protocols using unique molecular identifiers (UMIs) will generally contain one read with the cell and UMI barcodes plus adapters but without any transcript sequence.
