WebUsing RPKM/FPKM normalization, the total number of RPKM/FPKM normalized counts for each sample will be different. Therefore, you cannot compare the normalized counts for each gene equally between samples. ... Rather, it uses the raw counts and models the normalization inside the Generalized Linear Model (GLM). WebWhile we need the raw count data to use R packages such as edgeR (Chen et al. 2024) and DESeq2 (Love, Anders, and Huber 2024), calculating sample distances (used in the visualizations in this section) should be done on some form of normalized data. This data can either be RPKM/FPKM/TPM/CPM or vst-transformed (raw-)read counts.
