Dear Team,

I am using chimera for a typical protein-ligand docking study. The ligands were prepared in chimera itself using the dockprep options using gasteiger charges and amber ff14SB force field. While docking the same using AutoDock Vina function in Chimera , we encountered few errors for some of the ligands. The errors are explained as follows :

1. "" Ho" is not a valid dock type AutoDock atom types are case-sensitive."

2. Autodock Vina Error on Chimera: "ValueError: Could not find an atomic number for Hc Hc"

Any inputs regarding these will be helpful in resolving the issues.

Regards,

Utkarsh
