Hi Pietro, There is something that phenix.mr_model_preparation cannot read in Japanin.hhr (attached): phenix.mr_model_preparation Japanin.hhr gives the same error. I'll copy Gabor Bunkoczi and see if he can help with this. All the best, Tom T >> Dear all, >> >> my run of phenix.mr_rosetta stops with: >> >> ******************* ERROR ENDING *************** >> Inconsistent query numbering >> >> ******************* ERROR ENDING *************** >> >> I attach script and logfiles. >> >> Any suggestions? >> >> Thanks >> >> Pietro >> _______________________________________________ >> phenixbb mailing list >> phenixbb(a)phenix-online.org >> http://phenix-online.org/mailman/listinfo/phenixbb >>

Validation question: R-factor (all) and # of unique reflections (all)
by Young-Jin Cho 05 Jul '11

05 Jul '11

Hi everyone, While I am trying to deposit, I am faced with several things that I am not sure: FYI. I am in the <Refinement Statistics> section (Auto Dep Input Tool) in the PDB bank. Most values are came from pdb file that was made from phenix.refine but it asks me "R-factor (all)" that satisfy the limits established by high & low resolution cut off and "number of unique reflections (all)". My simple question is if phenix has those kind of information, if so where I can find them. Another question is if I changed water (deletion or changed occupancy) based on 'precheck', should I run phenix.refine again to get R/Rfree values in correct? I am not sure if these are captured by PDB automatically or not. (seemingly they do like that at this point but not 100% sure yet.) With many thanks~ Young-Jin

Hi Young-Jin, > I feel like I should calculate R(all). As mtz file is usually big, > how can I extract Fobs and Fmodel from phenix generated mtz file? If you feel you want it, then go ahead, and this command might be of help here: phenix.mtz.dump data.mtz --column-data-format=spreadsheet -c Yet another (easier) alternative is to run a dummy phenix.refine run like this: phenix.refine data.mtz model.pdb xray_data.r_free_flags.ignore_r_free_flags=true main.number_of_mac=1 strategy=none output.prefix=junk then take the reported R-factor (Rwork will be equal to Rfree, so take any of them), and discard the files. All the best! Pavel.

Ligand woes
by José Trincão 05 Jul '11

05 Jul '11

Hello all, I have been having very weird problems refining a structure with several ligands. The weirdest problem is that if I try to run ligand fit giving just the name of the ligands, no problem - it finds the ligands (FAD and MTE). I save the pdb with all the ligands in and phenix.refine complains that MTE is not recognised, I have to run ready-set. I do it. Run phenix.refine again, and now it complains with the following: Number of atoms with unknown nonbonded energy type symbols: 116 "HETATM18439 C1' MTE A3003 .*. C " "HETATM18441 C2' MTE A3003 .*. C " "HETATM18443 C3' MTE A3003 .*. C " "HETATM18444 O3' MTE A3003 .*. O " "HETATM18474 N9A FAD A3005 .*. N " "HETATM18475 C8A FAD A3005 .*. C " "HETATM18476 N7A FAD A3005 .*. N " "HETATM18477 C5A FAD A3005 .*. C " "HETATM18478 C6A FAD A3005 .*. C " "HETATM18480 N1A FAD A3005 .*. N " ... (remaining 106 not shown) Any help will be greatly appreciated.

NCS Restraints
by Yuri 01 Jul '11

01 Jul '11

Hi Pavel, >It's rather packing.. Say, if more than one copy packs in the > asymmetric >unit then you have NCS, roughly speaking.. So is it correct to say that in cases where you have 1 molecule per ASU, there will be no NCS only crystallographic symmetry?? > In other words, if for the same enzyme one crystal goes to 3.1 and > another 1.5 A could one have significant NCS but not the other? >I'm not sure I understood this... May some one else did? I was trying to understand if this phenomenon would be noticeable depending on the resolution only... You and Nathaniel pretty much answered this now... -- Yuri Pompeu

NCS restraints
by Yuri 01 Jul '11

01 Jul '11

Hello, I have some fundamental questions about NCS: 1- I think its somewhat of a consensus that at higher res. it should not be used to avoid missing out "real" detailed discrepancy. Is this true? 2- Should one try to use it in lower res data (3 A and worse)? 3- Is the presence of NCS macromolecule specific, or crystal specific? In other words, if for the same enzyme one crystal goes to 3.1 and another 1.5 A could one have significant NCS but not the other? Thanks or any clarification -- Yuri Pompeu

phenix.ligand_identification problem
by Andrzej 29 Jun '11

29 Jun '11

Dear All, I'm having problem with running ligand_identification script. All well up to the point where the ligand library is created and then for each ligand following error is displayed: Running job sequence 13, ligand 14, in /share/scratch/an... Sorry, resolve was not able to finish on the first cycle I suspect it has something to do with resolve size but there is no keyword like resolve_size for ligand_identification. I've tested my input files with 1.7.1-743 and dev-738 release - same results. Thanks in advance for the support!

Difference Map positive peaks in release dev-798
by Yuri 27 Jun '11

27 Jun '11

I was wondering if anything changed (weights or something) in the way the difference maps are calculated? I just ran refinement on a 1.3 structure and a hexacoordinated Mg2+ ion has significant positive density peak even at occupancy 1.0. I had not noticed that before. My ligand also does have positive peaks, but refine gives it a .91 occupancy. I wonder if I am missing some parameter cif file or some definition that would make the positive peaks decrease? Thank you -- Yuri Pompeu
