I'm looking into it now. I found instructions on their website for adding gene definition databases for non-human species, but they need to be in the USCS Genome Browser. I'm studying poplar, which is not... but I found in literature ANNOVAR was somehow used for rice, which isn't either.
Do you know how to add databases for species not included in the USCS Genome Browser, or could you point me in the right direction? Thanks.
