I am starting using topGO for my GO enrichment analysis and I am running fisher and ks separately. Fisher works fine, but I am not sure about my ks results. My question is: for the ks test, can I use a score different to a p-value? At the moment, I'm working with tajima's D, which generates values between -4 and 4, and my Selected Genes are those with a value higher than 2. So, I want to know if that does not represent any conflict for ks at the moment to run the test.
