is phenix trying to polymerize b-octyl glucoside?
I'm refining a model with some molecules of the detergent b-octyl glucoside (BOG). I got BOG.cif from a recent ccp4 library, so not sure if this is a suggestion for phenix or ccp4, but: If two BOG molecules are consecutive in the pdb file, phenix stops in setup because it can't find atom HO1 to delete. Even if I had H's in my model there would be no HO1 because O1 is in glycosidic linkage with the octyl chain. I'm guessing phenix somehow realizes there is a sugar and when two are consecutive it autogenerates a link to make a glycosidic bond between them - not appropriate in the case of BOG. easy work around is to intersperse with non-sugar molecules, but if there is a better way, I'll take it. ed RuntimeError: delete_atom_in_place: unknown atom_id: HO1 apply_mod failure: pdbres="BOG R 18 " segid="R " comp id: BOG mod id: DEL-O1 Version: dev Release tag: 1420 Platform: intel-linux-2.6-x86_64 linux
Hi Ed, I can have a look right now if you send me PDB and CIF files.. Thanks, Pavel On 8/8/13 8:42 PM, Edward A. Berry wrote:

Hi Ed, this should work in next nightly build. Pavel On 8/8/13 8:42 PM, Edward A. Berry wrote:
