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. WebNOTE: This video by StatQuest shows in more detail why TPM should be used in place of … macchi menuplan
