WebRPKM/FPKM (not recommended for between sample comparisons) While TPM and RPKM/FPKM normalization methods both account for sequencing depth and gene length, RPKM/FPKM are not recommended. The reason is that the normalized count values output by the RPKM/FPKM method are not comparable between samples.
