WebThe Cancer Genome Atlas (TCGA) is a landmark cancer genomics program that sequenced and molecularly characterized over 11,000 cases of primary cancer samples. Learn more … WebA common misconception is that RPKM and TPM values are already normalized, and thus should be comparable across samples or RNA-seq projects. However, RPKM and TPM represent the relative abundance of a transcript among a population of sequenced transcripts, and therefore depend on the composition of the RNA population in a sample.

FPKM normalizes for both sequencing depth and genome size. Those specific packages want non-normalized counts as the expression metric. This means the number of reads mapped to a particular gene or feature.
