I have 4 chipseq data (Bam files) files from Input, control treated and knockout of a gene. Now while preparing these samples different amount of DNA was processed/ pooled, because of inherent experimental problems. I want to normalize all four samples to fixed value and then analyze these samples. How best/ tool/ software I can do this normalization? Is it possible to get bam/ sam files of such normalized data as I would like to use NGS plot to generate figures for binding pattern.
