I think what I had in mind is pre-computed masks. Leap does, in
principle, "know" what it is dealing with because eventually it is all
based on residue names (there is a set of residue names for proteins,
another for DNA/RNA, etc). The task for leap (but there is apparently
no mechanism for this yet) or ParmEd would then be to appropriately tag
molecule types in the prmtop file. This could also be used by a user
to shorten overly long masks.

Ok, many thanks.
Cheers,
