Among many tools for over-/under-representation analysis there are few which are not constrained to fixed list of species.
There one have to just provide already available association of genes with functional categories.
I wonder if you know any other "open-species" enrichment analysis tools.
I'm mostly interested in analysis of InterPro enrichment tools, where analysis rely on user submitted population and experimantal sets with IDs and file with IDs' association with InterPro IDs.
I ended with creation of GO-like association and obo files for InterPro and use Ontologizer program. Much work to do but works fine.
