Error in phenix.autobuild
by Tanner, John J. 27 Jun '12

27 Jun '12

Can anyone shed light on the error below? The situation is that I have a ~90% complete model from refinement (r_work = 0.2415, r_free = 0.3167), and I want phenix.autobuild to build the rest of the structure. I issued this command: phenix.autobuild data=../ccp4/DrPRODH3-6_1_scala2.6Ang.mtz model=Refine_9/DrPRODH_refine_9.pdb seq_file=../seq/DrPRODH-noMet1.fasta rebuild_in_place=False nproc=3 I got this error: [tannerjj@europa AutoBuild_run_2_]$ tail -n20 AutoBuild_run_2_1.log Output space group: P 1 21 1 (No. 4) Columns of data in AutoBuild_run_2_/refinement_PHX.mtz: H K L FreeR_flag F_DrPRODH3-6 SIGF_DrPRODH3-6 Unit cell: (46.806, 95.875, 70.504, 90, 107.733, 90) Space group: P 1 21 1 (No. 4) Using AutoBuild_run_2_/refinement_PHX.mtz for refinement Correcting data file /titan/tanner/DrPRODH/ccp4/DrPRODH3-6_1_scala2.6Ang.mtz for anisotropy and writing to AutoBuild_run_2_/aniso_data_PHX.mtz Getting overall aniso B from datafile... *************ERROR ENDING ******************* **************************************** AutoBuild Input failed iotbx InternalError: /net/longnose/scratch2/phenix/phenix-1.7.3-928/cctbx_project/iotbx/mtz/dataset.cpp(97): IOTBX_ASSERT(strlen(label) < sizeof(column_ptr->label)) failure. **************************************** *************ERROR ENDING *******************

occupancy group definition
by Christian Roth 26 Jun '12

26 Jun '12

Dear All, I have tried an occupancy refinement for a partially modifed residue. I have split the residue in altloc A and B and the modification (PMSF) is attached on B. I included the PMS moiety as part of the residue and gave them altloc B. I created the cif link. The refinement resulted in a strange mixture of occupancys for PMS around 0.8 and both Serins 0.23 an 0.77. So PMS is not part of the residue. I am not sure about the correct syntax for the constrained group. At the moment I have used constrained_group { selection = chain A and resseq 130 and altloc A selection = chain A and resname PMS and altloc B } However the Serine pat of altloc B refines to a value not compatible to the PMS values or the Altloc A value of the serine. How do I incorporate the altloc B for the serine? Thanks in advance for your help Christian

geometry weight help
by 周文昌 25 Jun '12

25 Jun '12

Dear all, Last week, I played a little bit with geometry weight in phenix refinement. When I check the log file, what I found is that if I use wxc_scale and fix_wxc in my refinement, actually phenix will ignore the wxc_scale, while if I only use wxc_scale, phenix will follow the value specified in the command line, but the wxc value will change from one macro cycle to another cycle. Below shows one of my examples in which the wxc_scale values are ignored when I use wxc_scale and fix_wxc at the same time. Anyone has similar problems? Thanks for all your considerations. ################## Command line arguments: "../new-unique.mtz" "../3tx8.pdb" "fix_rotamers=true" "strategy=individual_adp+individual_sites" "wxc_scale=0.01" "refinement.input.xray_data.labels=FP,SIGFP" "fix_wxc=10" "--overwrite" refinement.target_weights.wxc_scale = 0.01 refinement.target_weights.fix_wxc = 10 wxc_scale = 0.01 fix_wxc = 10 | XYZ refinement: T = Eexperimental * wxc * wxc_scale + Echem * wc | | wxc = 10.000000 wxc_scale = 1.000 wc = 1.000 | ... ################## Wenchang

dihedral restraints problem with alternate conformations
by Benoît Masquida 25 Jun '12

25 Jun '12

I am having an issue refining 2 superimposed MES molecules A and B (morpholino ethane sulfonic acid, buffer seen in the density). phenix.refine works fine up to the end where it crashes because of the following error: Duplicate dihedral restraints: tor id: var_10 residue: MES, conformer "A" atoms: "HETATM 3993 O1 AMES T 1 .*. O " "HETATM 3994 C2 AMES T 1 .*. C " "HETATM 3995 C3 AMES T 1 .*. C " "HETATM 3996 N4 AMES T 1 .*. N+1" I can't see where is the conflict since all atoms have distinct labels and I provided the CIF file generated with phenix.elbow. What should I change to circumvent this problem? Thanks Ben

mr_rosetta problem
by Andreas Forster 24 Jun '12

24 Jun '12

Dear all, especially Tom T and Laurie Betts: I've recently installed phenix-dev-1084 and Rosetta 3.4 on RHEL 6.2. No problem. When I test the rosetta commands with phenix_regression.wizards.test_command_line_rosetta_quick, the first 12 of 39 tests succeed but test_prerefine fails and the process aborts. This is the error in the log file: /csb/soft/Linux64/share/rosetta3.4/rosetta_source/bin/mr_protocols.default.linuxgccrelease: error while loading shared libraries: libdevel.so: cannot open shared object file: No such file or directory libdevel.so exists, in the right place I venture to say: ls -l /csb/soft/Linux64/share/rosetta3.4/rosetta_source/build/src/release/linux/2.6/64/x86/gcc/4.4/libdevel.so -rwxr-xr-x. 1 csbadmin csb 6437 Jun 23 18:44 /csb/soft/Linux64/share/rosetta3.4/rosetta_source/build/src/release/linux/2.6/64/x86/gcc/4.4/libdevel.so Besides the tests failing, the actual mr_rosetta run fails as well, as one would expect, with the same "missing library" error. This problem has been reported before (http://www.phenix-online.org/pipermail/phenixbb/2011-May/017157.html), but I can't find a solution. Is there one? Thanks. Andreas

Run time error while refining
by Subhani Bandara 22 Jun '12

22 Jun '12

Hi everyone, I got the following error message while running refinement in mac, using PHENIX-1.8-1069. This occured when refined after editing Ramachandran outliers in coot, without applying Ramachandran restraints. Not sure wether it has something to do with this. RuntimeError : Estimated memory allocation for cubicles exceeds max_number_of_bytes: This may be due to unreasonable parameters: cubicle_edge=5 space_span=(3528.41,3528.41,3442.53) n_cubicles=(706,706,689) max_number_of_bytes=2147483648 Any suggestions! Thanks Subhani

Dear Phenix developers, If I want use the automatic TLS definition the following error appears. At least the first error line with invalid iteral does also appear int the last verification step of the validation against the supplied sequence file.
