I have two different ChIP-seq data for different proteins, I have aligned them to some fragments in the DNA. Some of these fragments get zero read count for one of them or for both. To be able to say these fragments has protein X much more than the protein Y, I use student's t-test.
I wonder if It would be better to remove the zero values from both of the data showing rpkm values for each fragment. Moreover, they pose problem when I want to use log during data visualization part.
What would you suggest?
