Thanks to all who help me answering my questions!
I have huge list of genes from different tissues and conditions and I would like to compare these profiles with some other results. Im trying to find which genes/metabolic pathways from my list could be "new developed" in each tissue. Usually all approache are designed to find from a list of genes de ontology...etc but how can I relice among 11000 genes which one has not found before in that tissue?
My best regards and thanks in advance
