[PyMOL] Possible hydrogen addition bug

2013-06-07 Thread Matthew Baumgartner
Hi, I may have found a bug in the way pymol interprets connectivity of atoms. I noticed this in one pdb structure that I am working with 1RV1. Steps to reproduce: fetch 1RV1 #extract one of the ligands to it's own object extract 'lig', /1RV1//A/110 #add hydrogens h_add lig Now look at atom C2

Just adding that N1, C2, and N3 in that ring are all sp2 hybridized. So the H on the adjacent N is also in the wrong place. Q: How is PyMOL determining ligand atom hybridization, by the way? Not using the ligand CIF file at PDB, I guess? Bob Hanson On Fri, Jun 7, 2013 at 10:51 AM, Matthew
