ChIPQC cross-coverage plot
Hi All, I'm analyzing some chipseq data and getting a little odd cross-coverage plot. For info- I'm using Chipqc package to create cross -coverage plot and the dataset is from E.coli. I'm wondering why this doesn't have a small peak at readlength (36bp)? image link- https://ibb.co/j6hhjCc
Another question that comes to my mind is, the dataset seems to have 400 bp fragments ( size of the fragment extracted from the gel electrophoresis or expected from sonication). Why do see another peak at ~200bp?
