Closed:What's the best way to find out 1:1 ortholog presented in multiple speceis

Question

[yuanfeifuzzy]

I am trying to find a way to get all 1:1 ortholog presented in multiple species from OMA database, but unfortunately, I only can get orthologs presented in all interested species, while have no way to make sure they are 1:1 ortholog. Anyone can help me with this?

By saying 1:1 ortholog in multiple species, I mean something like this (an example from OrthoDB):

http://orthodb.org/?level=40674&species=40674&universal=1&singlecopy=1

The result showed in that page is what I want: for all 41 mammals, there are 837 ortholog groups, each group have exact 41 genes and each gene is single-copy gene in each species.
