Hi,

I get a minimisation error - Atom type "Br" is not supported by MMTK - when trying to minimise a PDB that contains a bromonaphthalene covalently bound ligand. 

I have read the post by neelagiri.d at gmail.com  and note the Cl substitution does make this work but my Br is part of the molecule and so GAFF/Antechamber should be able to handle it I thought?

Really appreciate any help.

Best wishes,
Kyle
