WebJan 1, 2024 · Read per kilobase per million (RPKM) is a kind of normalization for RNA-Seq analysis to compare the number of reads among the samples. This normalization is because of some biases, including reads with different expression levels. Therefore, RPKM divides the number of mapped reads by the number of total reads. WebFPKM, RPKM, and TPM option perform normalization for sequencing depth and gene length, whereas RUV and upper quartile eliminate unwanted variation between samples.
