WebMay 8, 2014 · I’m fairly certain TPM is attributed to Bo Li et. al. in the original RSEM paper. RPKM/FPKM. Reads per kilobase of exon per million reads mapped (RPKM), or the more generic FPKM (substitute reads with fragments) are essentially the same thing. Contrary to some misconceptions, FPKM is not 2 * RPKM if you have paired-end reads. Web1) scaledTPM is TPM's scaled up to library size, while lengthScaledTPM first multiplies TPM by feature length and then scales up to library size. These are then quantities that are on the same scale as original counts, except no longer correlated with feature length across samples. 2) No difference. tximport is simply importing the TPMs and ...
