WebMar 23, 2024 · I am using a pipeline (bam -> featurecount-> EdgeR) to do some RNASeq analysis of several groups and sub-groups. For example, I have the following dataset with two types (T1 and T2) and T1 has three groups G1, G2 and G3, T2 has G5 and G6 groups. I would like to find TPM numbers, fold-change and FDR for all the genes and Groups. WebMay 20, 2024 · Takes a count matrix as input and converts to other desired units.
