Misuse of RPKM or TPM normalization when comparing across

WebTo normalize these dependencies, RPKM (reads per kilobase of transcript per million reads mapped) and TPM (transcripts per million) are used to measure gene or transcript expression levels. A common misconception is that RPKM and TPM values are already normalized, and thus should be comparable across samples or RNA-seq projects. WebA simple method of normalizing count data is to calculate the fragments per million mapped fragments (FPM, equal to CPM) value and then transform this with log2. Opposed to FPKM and RPKM this does not include the gene-length … WebA common misconception is that RPKM and TPM values are already normalized, and thus should be comparable across samples or RNA-seq projects.
