[ensembl-dev] HomologyAdaptor - function not working

[Marc P. Hoeppner]

Hi,

the members where genes, but the method_link_species_set was the EPO 35 
mammal alignment, which I am guessing wouldn't work in this context? If 
so, maybe the API could throw something to alert the user that the mlss 
must be of the type 'ENSEMBL_OTHOLOGUES' ?
