Thanks for the answer Ben,
Unless I miss totally the point, the transfer_xyz function allows one to agglomerate a set of models to produce an average structure. I am more interested in the other type of clustering evoked by Min-yi Shen, namely : define subset of similar structures. Can you tell me if there is anything to do that in MODELLER ? If that is not the case, I'll resort to a trick as the one suggested by Min-yi Shen.
--Thanks
