The .gtf file used here was same as used for getting the counts from htseq-count. Then I apply your function tpm to get TPM from raw counts and exon length per gene. Can you please guide me if I am doing it correct?

WebJul 9, 2015 · Here’s how you calculate TPM: Divide the read counts by the length of each gene in kilobases. This gives you reads per kilobase (RPK). Count up all the RPK values in a sample and divide this number by 1,000,000. This is your “per million” scaling factor. Divide the RPK values by the “per million” scaling factor.
