Chip seq reads normalization

WebApr 11, 2024 · RPKM (Reads Per Kilobase per Million mapped reads）was made for single-end RNA-seq, where every read corresponded to a single fragment that was sequenced. FPKM (Fragments Per Kilobase per Million mapped fragments) is very similar to RPKM. We divide the number of fragments of a gene by the total sequencing depth, and the ratio is … WebJun 21, 2024 · Input normalization in ChIP-seq. If I subtract input counts from ChIP counts (for every gene, since I have one peak per gene) I get negative values for most genes. This makes sense to me, because (as can be seen in the figure) input and IP have same sequencing depth but IP is very biased towards few genes with lots of counts.
