[phenixbb] Molybdenum cofactor refinement

Hi all,

I'm using phenix.refine to refine a structure of a Molybo-protein at 1.9Å.
The MGD cofactors (molybdopterin guanine dinucleotide) are being refined
with a weird distorted geometry causing some clashes. The Fo-Fc maps show
that something is going wrong in the aromatic rings interatomic distances.

I'm using the readyset to pick up MGD and metal restraints.
Am I using the right protocol?

Best regards,
Cristiano Mota
