[chimerax-users] Cleaning a pdb file

[Elaine Meng]

Hi Martin,
If by programatically you mean by python code, that is beyond my area of expertise and someone else will have to advise.  

Of course you can open the structure and use commands like "delete solvent" or "delete ligand" whatever else you decide needs deleting, and then save a PDB file... however, ChimeraX does not yet have a Dock Prep tool like Chimera does.  The Chimera Dock Prep tool does several things like fixing up truncated side chains, adding hydrogens and charges, etc.  ChimeraX has "addh" and "delete" so you can use it for those now, but not all of the other dock-prep steps.

I hope this helps,
Elaine
