Dear David,
Please find attached the input pdb file for the ligand. The charge is -1, I
used -nc flag to specify the charge of the system. Is that correct? By the
way, the ligand already has hydrogens before using antechamber.
antechamber -i 6058_rep0_pose1.pdb -fi pdb -nc -1 -o 6058_rep0_pose1.mol2
-fo mol2 -c bcc
I check the sqm.out file, the calculation is completed.
Best regards,
Rui
