WebedgeR uses a normalization procedure called Trimmed Mean of M-values (TMM). DESeq2 implements a normalization procedure using median of Ratios, which is obtained by finding the ratio of the log-transformed count of a gene divided by the average of log-transformed values of the gene in all samples (geometric mean), and then taking the median of these … WebSep 3, 2015 · Trimmed Mean of M-Values (TMM) TMM normalization is the EdgeR package's default normalization method and assumes that most genes are not differentially expressed. It calculates a normalization factor for each gene, though this correction factor is applied to library size (i.e. sequencing depth) rather than not raw counts.
