WebJul 22, 2015 · Here’s how you do it for RPKM: Count up the total reads in a sample and divide that number by 1,000,000 – this is our “per million” scaling factor. Divide the read counts by the “per million” scaling factor. This normalizes for sequencing depth, giving you reads per million (RPM) Divide the RPM values by the length of the gene, in kilobases. WebNov 30, 2024 · Two represents the smallest sample size for each group in our experiment. In this dataset, we choose to retain genes if they are expressed at a counts-per-million (CPM) above 0.5 in at least two samples. We’ll use the cpm function from the edgeR library (M. D.
