WebAug 1, 2024 · However, there are differences between the RNA-seq and ChIP-seq count analyses. In RNA-seq experiments, most reads are in the exome, where read count can be normalized by the total number of reads mapped to all genes. In contrast, most ChIP-seq reads are outside of peaks. The fraction of reads in peaks (FRiP) score typically ranges …
