I am doing a simulation on a protein having 2 zinc ions; but when I try to
generate the psf - it gives me the following error:
unknown residue type ZN

I think the problem is its coordination with protein because if loaded
into VMD the it says unusual bond between residue and zinc atom - how to
fix this?
