[Chimera-users] PROBLEM IN ENERGY MINIMIZATION

[Prabuddha Bhattacharya]

Dear Chimera,

I have been facing a problem recently while using UCSF Chimera. After
opening the structure of ligands in the chimera window as .pdb file, when
ever I am trying to minimize the energy (Tools-->Structure
Editing-->Minimize Structure) of that ligand in (which is in .pdb form), I
am getting the following error message: "Failure running ANTECHAMBER for
residue". I am using "AMBER ff14SB" (for standard residues) and "Gasteiger"
(for other non-standard residues).

Upon trying out with "AM1-BCC"  (for other non-standard residues), I am
getting an altered compound so that cannot be perhaps tried.

Kindly find attached the .pdb files for the ligands I am trying to minimize
the energy, and a word file containing the screen shots of the step-by-step
messages leading to the error message that I am getting.

I will be highly grateful if you can help me in sorting out the problem.

Thanks in advance,

Best Regards,
