[Chimera-users] Chimera help - attempted to do minimization

Hello, I attempted to do minimization on my mutant protein but I get this error when I try to run it: AttributeError: '_molecule.Atom' object has no attribute 'gaffType' File "C:\Program Files\Chimera 1.14\share\MMMD\MMTKinter.py", line 695, in _addStandardResidue "amber_atom_type": a.gaffType, I've attached the reply log for more details. Please let me know if I need to fix anything, thank you. Best regards, Jay Chen
