Problem with version 1.7.1-743 on OSX
by Miguel Ortiz Lombardía 07 Feb '12

07 Feb '12

Dear phenix developers, Last Friday (April 29) we upgraded phenix to its most recent version (1.7.1-743). Installation went smoothly on both Mac (10.6.7 64-bit) and Linux (Ubuntu 10.10 64-bit) machines. However, we observe that we cannot use phenix.refine (I don't know for the rest of the applications) from the GUI on the Macs. phenix.refine does work from the command line, though. So, whenever we try to add a pdb in the GUI, we get this error message: This application does not support the file type for /path/to/the/file.pdb (format: txt) If we try to open an mtz, it sometime works, but most often we get: PHENIX did not recognize the file type for /path/to/the/file.mtz! and on the terminal from where the GUI was started we can find: **SYMMETRY OPERATOR ERROR** Error in interpreting symop " X+2/3, Y+1/3, Z+1/3 " **SYMMETRY OPERATOR ERROR** Error in interpreting symop " -Y+2/3, X-Y+1/3, Z+1/3 " (and so on, so forth). Any clues ?

Re: [phenixbb] ADP refinement selection
by Pavel Afonine 16 Jul '11

Hi Christian, the problem is that you did not ask phenix.refine to refine the rest of the atoms isotropically (with your command below you only refine anisotropic ADPs of atoms in chain Q, and the B-factors of all the other atoms are not refined): > adp { > individual { > anisotropic = "chain Q" > } I would do it like this: adp { individual { anisotropic = chain Q and element CL isotropic = not (chain Q and element CL) } } Pavel.

Summer X-rays at the NSLS

Summer X-rays at the NSLS The PXRR operates five beamlines at the NSLS: http://www.px.nsls.bnl.gov/. Two of these are the undulator beamlines X25 and X29. The dipole beamlines X12-B and X12-C are available, and are very effective for conventional crystallography. There are efficient ALS-Style Automounters available -- 8400 crystals mounted in the last 12 months. Also, at beamline X26-C, we have a unique-in-the-US station for combined x-ray diffraction and single-crystal optical spectroscopies: http://www.px.nsls.bnl.gov/x26c/x26c_info.html Notice also our world-leading Mail-In crystallography program: http://www.px.nsls.bnl.gov/Mailin.html You may request access to any of these here: http://www.px.nsls.bnl.gov/beamtime_requests.html, and can look at the schedules for all five here: http://www.px.nsls.bnl.gov/ Stay tuned for the announcement in December of RapiData, our annual course in rapid data collection and structure solving: http://www.bnl.gov/rapidata/ Bob Sweet ========================================================================= Robert M.

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 28 Jun '11

28 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

Difference Map positive peaks in release dev-798
by Yuri 26 Jun '11

26 Jun '11

Pavel, I just ran the same job using the last official release (743). Some differences: >When the change occurred (between which version numbers)? Some where in between 743 and dev-798. >Does the peak disappear if you do the same calculation using an older > version? Yes, I see no positive or negative peaks for the Mg ion (nor my ligand). >There is no general remedy - it's all case-dependent. >Does its B-factor differ significantly from surrounding atoms? Yes, the B-factor for the ligand is 20 on average. The surrounding residues and cofactor are 10 or below. But, as I mentioned above, I see no positive peak density this time around. -- Yuri Pompeu

NCS error in Phenix 1.7.1-743
by Ngan Nguyen Bich 24 Jun '11

24 Jun '11

Dear all, I've got a problem when rerunning the same job of my project in the new laptop. I've found that it's because of the NCS restraint groups set-up In the old computer I set two NCS restraints groups as: First group: Reference group: chain A and sidechain and resid 3:216 and not (resid 63 or resid 66 or resid 81 or resid 93 or resid 133 or resid 135 or resid 181 or resid 184 or resid 193 or resid 194 or resid 212) Second group: Reference group: chain A and backbone and resid 3:217 and not (resid 63 or resid 133 or resid 135 or resid 184) And the refine_phenix run well in the old computer, but the new laptop with the error in the end of this letter. I've found that if I delete the backbone in the second group, it runs again. So I wonder that how I could refine NCS restraint of backbone now? Thank you in advance.

June 23, 2011, 9:30 AM Dear all dimer in AU average B factor 21 resolution: 1.78 each subunit shows 2 Tin atoms in the active site B factor for 2 tin in chain A 15 and 19 but B factor for other 2 tin in chain B 30 and 41 41 for tin which is between the 2 cysteine (photo attached) (occ: 0.25) this one which i am worry about ((because the average B factor for the surrounding amino acid is 20)) and 30 of the other one near phoshate (occ: 0.70) 1- i tried to change the occupancy or refine the occupancy for tin trying to reduce B factor (41) it works (reduced to 30) but it gives me a +ve peak what could i do to solve this problem?? 2- other trial to define charge for that tin HETATM 3241 SN SN C 3 6.543 -2.139 -14.821 0.25 41.55 SN4+ but it was the same result. --- is this definetion for that charge is OK or it is not enough in PDB file --- is this way is understandable by phenix.refine? i mean does phenix differentiate in refinment between SN, SN2+ and SN4+??
