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. WebNormalization by sequencing depth (i.e. total read count) is probably the simplest approach but is widely used. There are some drawbacks with this approach. For … brown check upholstery fabric
