edgeR is a tool for differential expression (DE) analysis of RNA-seq, ChIP-seq, CAGE, and SAGE data with biological replicates. The edgeR algorithm uses information from all the genes, computes the dispersion using a weighted likelihood and F-test techniques. For the normalization, it can use the trimmed mean of M-values, upper-quartile (UQ) procedure, Relative Log Expression (RLE), and DESeq. It can compare two groups, paired and unpaired, or use a Generalized Linear Model (GLM). The upper-quartile (UQ) procedure is also applicable to single-cell RNA-seq (scRNA-seq).
