I would like to use the Generic ontology term finder (online tool) for a list of genes but at the third step, it asks me to choose the annotation. The problem is that my species (Ovis aries) is not on the list. I have noticed that in several tools the annotation list is limmited in a specipic number of species. Is there any tool that it has a wider list of annotation files or a way to tranform my genes into another species? I tried biomart from Ensembl in order to convert my genes into human (orthologs) but it gives me as output only the IDs of the genes that are orthologous and not the coresponted IDs of human genes.
I'm really sorry if my question is a little bit complicated but I'm a little bit new in this kind of analysis. Thank you very much in advance.
