Problem with BOOST_ADAPTBX_FPE_DEFAULT and BOOST_ADAPTBX_SIGNALS_DEFAULT
by Sam Stampfer 25 Aug '09

25 Aug '09

Hi, I'm running the latest complete version of phenix (version 1.4-147, on Linux 2.6-x86 64). When I run my .csh file I get the following error (with the 4 previous lines included): /usr/local/phenix/phenix-1.4-147/build/intel-linux-2.6-x86_64/base/bin/python(PyDict_SetItem+0x1fd) [0x446bdd] /usr/local/phenix/phenix-1.4-147/build/intel-linux-2.6-x86_64/base/bin/python [0x4396e4] /usr/local/phenix/phenix-1.4-147/build/intel-linux-2.6-x86_64/base/bin/python [0x4470a9] /lib64/libc.so.6 [0x30fca322a0] Segmentation fault (Python and libc call stacks above) This crash may be due to a problem in any imported Python module, including modules which are not part of the cctbx project. To disable the traps leading to this message, define these environment variables (e.g. assign the value 1): BOOST_ADAPTBX_FPE_DEFAULT BOOST_ADAPTBX_SIGNALS_DEFAULT This will NOT solve the problem, just mask it, but may allow you to proceed in case it is not critical. When I type the command "setenv BOOST_ADAPTBX_FPE_DEFAULT 1" and then run my .csh file, it runs for a slightly longer period of time before ending with a different error: 311240e000-3112410000 rw-p 0000e000 fd:00 14237822 /lib64/libbz2.so.1.0.4 2ad973412000-2ad973414000 rw-p 2ad973412000 00:00 0 2ad973429000-2ad97346d000 rw-p 2ad973429000 00:00 0 2ad97346e000-2ad9734af000 rw-p 2ad97346e000 00:00 0 2ad9734e1000-2ad973563000 rw-p 2ad9734e1000 00:00 0 2ad973563000-2ad973567000 r-xp 00000000 fd:00 5727920 /usr/local/phenix/phenix-1.4-147/build/intel-linux-2.6-x86_64/base/lib/python2.6/lib-dynload/time.so 2ad973567000-2ad973666000 ---p 00004000 fd:00 5727920 /usr/local/phenix/phenix-1.4-147/build/intel-linux-2.6-x86_64/base/lib/python2.6/lib-dynload/time.so 2ad973666000-2ad973668000 rw-p 00003000 fd:00 5727920 /usr/local/phenix/phenix-1.4-147/build/intel-linux-2.6-x86_64/base/lib/python2.6/lib-dynload/time.so 2ad973668000-2ad97366d000 r-xp 00000000 fd:00 5727941 /usr/local/phenix/phenix-1.4-147/build/intel-linux-2.6-x86_64/base/lib/python2.6/lib-dynload/select.so 2ad97366d000-2ad97376c000 ---p 00005000 fd:00 5727941 /usr/local/phenix/phenix-1.4-147/build/intel-linux-2.6-x86_64/base/lAbort However, the file ran fine and successfully output an improved .pdb file without any BOOST-related problems on my PI's Mac- she is running version 95 of Phenix (which I was unable to obtain for linux- is it available somewhere?) Can you help me with this? Thanks! -Sam

ruthenium parameters
by Terry Lang 24 Aug '09

24 Aug '09

Hey Everyone, I am working on an xray structure that contains a ruthenium. I have been able to use elbow to create a cif file that phenix can read and refine without throwing error messages. However, there is a large amount of positive electron density after the refinement. I am looking into modeling coordinate waters, but I first wanted to check that the ruthenium is being read correctly by phenix. How do I figure out if it is properly recognized (eg correct scattering factors, bond and angle restraints, etc)? Thanks, Terry -- P. Therese Lang Postdoctoral Scholar Alber Lab, UC Berkeley

phenix.refine 1.3 vs. 1.4 map quality ?
by William G. Scott 23 Aug '09

23 Aug '09

Hi folks: About a year ago I refined a 1.6 Å RNA structure with phenix.refine 1.3b-rc6 and then got distracted. I picked it up today and essentially repeated the last round of refinement with 1.4-57 (and also 1.4-159). The maps are subtly different, but consistently slightly worse with 1.4. Here are two examples: http://sage.ucsc.edu/~wgscott/mystuff/old_vs_new.pdf In the second example, this would lead to deletion of one of the octahedrally coordinated waters on a known Mg++ ion. 2OEU is similar, except 2.0 Å resolution, and it has Mn2+ instead of Mg ++. A similar thing happens with the corresponding water in that structure. Has the weighting for the bulk solvent mask or something like that been increased? Thanks. Bill Scott

difference in B factor for NCS groups
by James Whittle 21 Aug '09

21 Aug '09

Dear all, I'm working with a structure were one NCS copy has significantly high B-factors than the other. That one copy makes few crystal contacts to stabilize it. Is there a recommended way to adjust the refinement to reflect this ... using TLS? Decreasing b_factor_weight? Is there a way refine a group_b to be added to the b-factor of each atom in that chain? --James

Error in running Autosol....
by S. Karthikeyan 19 Aug '09

19 Aug '09

Dear All, I am using phenix-1.4-138 in RHEL5 Xeon-64 bit workstation. I am trying to solve a structure of Se-Met through phenix.autosol_gui. Once the programs starts it goes to several stages including converting from mtz to sca, xtriage and so on. Finally it gives an error message as follows: ******************************************************************************** Failed to carry out AutoSol_scale_and_analyze_mad: None of the solve versions worked See overall log file and also solve log file (in AutoSol_run_2_/LAST.LOG) ******************************************************************************** I found the LAST.LOG file is empty. I am trying to find out what could be problem? Any suggestions or help is much appreciated! Thanking you S.Karthikeyan

Problem with LLP ligand
by James Naismith 19 Aug '09

19 Aug '09

Dear All, I am trying to refine a structure which has a Lys linked to PLP. In the PDB this is called LLP. When I take it through refine it crashes complaining about the ligand. "Sorry : Fatal problems interpreting PDB file: Number of atoms with unknown nonbonded energy type symbols: 8 Please edit the PDB file to resolve the problems and/or supply a CIF file with matching restraint definitions, along with apply_cif_modification and apply_cif_link parameter definitions if necessary (see phenix.refine documentation). Also note that phenix.elbow is available to create restraint definitions for unknown ligands. Traceback: None " I know I have to use REEL to fix this in some way. I have used REEL to make ligands not bound to protein before. It is how to do this when the ligand is covalently bound that I am stuck with.

RESOLVE with RNA/protein structure at low resolution
by Peter Grey 19 Aug '09

19 Aug '09

Hello all, I try to solve the structure of RNA and RNA/protein complex at low resolution (5A). Phases come from partial model MR solution. I would really welcome advice about density modification in such cases with RESOLVE.. Does the RESOLVE database of density distributions contain RNA/protein examples ? Can RESOLVE work at low resolution given that histograms profiles are at resolutions from 1.2 A to 4 A ? Many thanks for you help, Peter.

AutoBuild help
by Timothy C. Umland 18 Aug '09

18 Aug '09

I am new to running the AutoMR and AutoBuild Wizards, and I am having a problem getting AutoBuild to run. I have run AutoMR and it appeared to run fine, yielding a solution. However, when it did the default hand-off of the MR solution to AutoBuild, AutoBuild crashed. I then tried to run AutoBuild by itself, using the MR solution as the input model. Again, AutoBuild crashed. The error was the same in both cases. I was running AutoMR and AutoBuild from the command line. I am running Phenix version 1.4-3 on an Intel Mac (OS X 10.5.8). The AutoBuild error was **************************************************************************** **** Failed to carry out AutoBuild_build_cycle: child process stderr output: command: 'csh /AutoBuild_run_3_/TEMP0/RUN_FILE_1' sort: invalid option -- 4 Try `sort --help' for more information. **************************************************************************** **** I tried the suggested "sort --help", but at least to me it wasn't helpful. I am guessing that I have some incompatibility with my local installation of "sort" and Phenix? Any help is appreciated. Thanks, Tim

Re: [phenixbb] Error in running Autosol....
by Thomas C. Terwilliger 15 Aug '09

Hi Karthikeyan, I'm sorry for the trouble! I see that you are running the very latest phenix from last night. This version passed our automated tests and it appears fine in general. Somehow the solve scaling step is not working in your run. I haven't seen this happen before, but my guesses are: 1. I have been making small changes in the autosol printout and it is possible that there is a place where solve is printing something out and the format does not match the variable type, and I didn't catch it in our tests. If this is the case you should be able to find it by running from the command-line and adding the keyword debug=true and it should print out a clearer error message for you that you can send me. You can run from the command line in the same place you ran from the GUI by saying phenix.autosol autosol.eff debug=True because the GUI writes out autosol.eff when it runs, saving your inputs. Then you can override those values by putting debug=True on the command line. Other less-likely possibilities: 2. your input datafiles are of a type that was unexpected (normally .sca, .mtz are fine, but perhaps the columns in an mtz are unusual). 3. Your structure is very large or high-resolution. 4. Something is unusual in your setup so that not much memory is available. If none of these helps, you are welcome to send me the files and I'll check it out. All the best, Tom T >> Dear All, >> >> I am using phenix-1.4-138 in RHEL5 Xeon-64 bit workstation. >> >> I am trying to solve a structure of Se-Met through phenix.autosol_gui. >> Once the >> programs starts it goes to several stages including converting from mtz to >> sca, >> xtriage and so on. >> Finally it gives an error message as follows: >> >> ******************************************************************************** >> Failed to carry out AutoSol_scale_and_analyze_mad: >> >> None of the solve versions worked >> See overall log file and also solve log file (in AutoSol_run_2_/LAST.LOG) >> ******************************************************************************** >> I found the LAST.LOG file is empty. >> >> I am trying to find out what could be problem?
