[galaxy-user] ChIP-Seq Normalization to total number of reads

Dear Galaxy, I am trying to analyze my ChIP-Seq data from Illumina using Galaxy. I have 2 datasets that I want to compare after normalizing each of them to their respective inputs, and these 2 datasets have very different number of reads to start with, is there a way to first normalize each dataset to total number of reads in Galaxy? Thanks. Your help is very much appreciated. Catheryn
