Did you know... Retain order The retain_order setting keeps atoms in the original order, instead of sorting them by atom identifiers. The "original order" is defined by the rank property, so technically with retain_order=on, PyMOL performs a rank-assisted sort. Setting retain_order on or off triggers resorting of atoms. File Format Specifics vdb: Since PyMOL 1.8.6, retain_order is automatically set for VIPERdb files, because they don't have unique chain identifiers cif: When retain_order=on, then PyMOL will skip loading of missing residues, because it depends on sorting Syntax set retain_order,[0,1] Example Original PDB: <source lang="diff"> ATOM 1 CH3 ACE A 1 33.160 24.100 12.400 1.00 0.00 ATOM 2 HH31 ACE A 1 32.860 24.830 11.650 1.00 0.00 ATOM 3 HH32 ACE A 1 33.800 23.390 11.880 1.00 0.00 ATOM 4 HH33 ACE A 1 32.250 23.650 12.770 1.00 ..→
