WebIntro. limma is an R package that was originally developed for differential expression (DE) analysis of microarray data. voom is a function in the limma package that modifies RNA-Seq data for use with limma. Together they allow fast, flexible, and powerful analyses of RNA-Seq data. Limma-voom is our tool of choice for DE analyses because it: WebglmQLFit and glmQLFTest implement the quasi-likelihood (QL) methods of Lund et al (2012), with some enhancements and with slightly different glm, trend and FDR methods.

WebThe B-C contrast simply finds genes that are differentially expressed between B and C, nothing more and nothing less. The null hypothesis for B-C is that muB - muC = 0 where muB and muC are the expected log-expressions for the two groups. You can see that A cancels out just by elementary math: (B-A)- (C-A) = B - A - C + A = B - C + A - A = B - C. WebEdger User Guide - Bioconductor - Home
