How to correct translational psuedosymmetry
by Appu kumar 12 Aug '13

12 Aug '13

Dear all, I have processed a protein-DNA complex data with imosflm. Phenix.xtriage suggest that the is a off origin peak of hight 41.702 hight at fractional coordiantes of 0.500 0.021 0.500 with distance of 40.019 from origin. I am new to such kind of problem, so would you please suggest me how to solve the psuedosymmetry problem encountered in data process. The present unit cells are 55.41 109.72 66.61 90 98.74 90 in space group P1211 with p_value is 3.116e-04. Your help would be much appreciated Thank you Appu

is phenix trying to polymerize b-octyl glucoside?
by Edward A. Berry 09 Aug '13

09 Aug '13

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

Ensemble refinement?
by Joseph Noel 08 Aug '13

08 Aug '13

Is anyone having issues executing ensemble refinement in Phenix? I've tried several times now to run things and it always crashes without returning any maps and just returning a set of large PDB files such as: "TEAS-W273E-FPP-A_ensemble_0.6.pdb, TEAS-W273E-FPP-A_ensemble_0.8.pdb, TEAS-W273E-FPP-A_ensemble_0.9.pdb and TEAS-W273E-FPP-A_ensemble_0.1.pdb". The log file always ends with: " Time building chain proxies: 3.01, per 1000 atoms: 0.35 Number of scatterers: 8638 At special positions: 0 Unit cell: (125.75, 125.75, 120.07, 90, 90, 90) Space group: P 41 21 2 (No. 92) Number of sites at special positions: 0 Number of scattering types: 7 Type Number sf(0) S 19 16.00 P 2 15.00 Mg2+ 3 10.00 O 835 8.00 N 717 7.00 C 2765 6.00 H 4297 1.00 sf(0) = scattering factor at diffraction angle 0. AttributeError" I only entering a single chain with solvent and ions and hydrogens. All of the other parameters from the GUI are kept the same. Any suggestions or comments would be much appreciated.

Restraints file for a modified peptide
by Michael Feldkamp 05 Aug '13

05 Aug '13

I have a peptide that has a fluorescent tag attached to its N-terminus along with a unnatural amino acid incorporated into the sequence. I know how to generate .cif files for the individual ligands using elbow, but I'm at a loss as to get Phenix to recognize these modifications to the peptide so that it refines the structure as one molecule with covalent linkages between the fluorescent tag, peptide and modified amino acid. Any help would be much appreciated. Thanks, Michael

Molecular replacement pipeline MRage
by Morten Grøftehauge 05 Aug '13

05 Aug '13

Hi guys, So I've been trying out MRage. I used the GUI since I didn't care too much and just wanted it started. I noticed two things. It doesn't show you the best results so far. It doesn't even save the best results so far. Everything is hidden in a giant log file in the .phenix/project_data folder (.phenix is hidden so I'm guessing that means you don't want people snooping around in there?). I can grep the TFZ= lines with grep 'TFZ=' mr_pipeline.log > grep-TFZ.txtand sort them with sort -r -k 13 grep-TFZ.txt but I think this is a bit excessive for the average user. ... Oh, and now I tried to re-run the highest scoring model in Phaser and it crashed and took MRage with it. Are you sure MRage is out of beta? Trying to be facetious, not mean. Cheers, Morten -- Morten K Grøftehauge, PhD Pohl Group Durham University

How does phenix handle deuterium atoms in neutron diffraction data?
by Javier Gonzalez 02 Aug '13

02 Aug '13

Hello, I'm performing a joint neutron-xray refinement with phenix, for a dataset collected from a crystal exchanged with deuterated water, ie, all exchangeable H atoms are replaced by D. I was wondering whether phenix has libraries of .cif dictionaries (or equivalent) in order to handle the name "D" of some "H" atoms in the .pdb files? I would like to use those dictionaries to input into Coot, so that it can handle deuterated molecules during geometry regularization, real space refinement, etc. Any help will be greatly appreciated. Thanks, Javier -- Javier M. Gonzalez Protein Crystallography Station Bioscience Division Los Alamos National Laboratory TA-3, Building 4200, Room 202 Mailstop T001 work: (505) 667-9376 (temporary)
