[ensembl-dev] Extracting one-to-one orthologs subtrees and subfamilies

[alouis at biologie.ens.fr]

Hi everyone,

Does anybody know if it is possible (and how to do so if yes) to extract subfamilies and subtrees containing only one-to-one genes from specific set of species?

I tried to parse subtrees containing no duplication nodes, but it seems to miss some genes.

If anybody has an idea…

Thank you very much in advance,

Regards,
Alexandra
