MR Rosetta Error

05 Aug '13

Dear all I am trying to determine a protein structure using Rosetta MR. It is the first time to use Rosetta (Phenix). When I performed Rosetta MR via Phenix, I received the Error message as follows: What is wrong? What should I do to solve the problem? I use Ubuntu 12.10 as a platform.

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)

fix Ramachandran outliers
by Wei Shi 01 Aug '13

01 Aug '13

Hi all, I have a refined structure with phenix. The resolution=3.2 Å. After refinement, the R-work=0.2186, R-free=0.2864, Bonds=0.010, Angles=1.515. Ramachandran outliers: 4.8%, Ramachandran favored: 80.8%. Rotamer outliers: 14.5%, c-beta outliers: 2 clashscore: 16.28, overall score: 3.32 To fix the Ramanchandran outliers, in coot, by changing the phi-psi of the outliers, I could manage to move most of them to the allowed positions. But, after another refinement in phenix, those outliers come back. I am wondering whether any of you have any suggestions for me on how to fix these outliers. Also, I read in a previous post that “all outliers could be first fixed manually in Coot (also applying real-space refinement with Coot's Ramachandran restraints turned on), as the default potential is very tight and can pull residues the wrong way if they're starting from a very bad position”. I am wondering whether any of you have done this before in coot, and can you please tell me specifically how this is done. Thank you so much! Best, Wei

phenix-refine crash
by Carlos Frazao 31 Jul '13

31 Jul '13

Hi, After the last model building of my protein I am not succeeding to further refine its structure, because phenix.refine crashes. However, if I set "main.number_of_macro_cycles=0" the job reaches its expected end and outputs a .pdb file. If I set "main.number_of_macro_cycles=1" the job crashes a few lines after the log-file indication " ============================== Exporting results ==============================" and produces an incomplete .pdb file with part of the header. Alternatively, If I set "main.number_of_macro_cycles=2" the job crashes during "MACRO_CYCLE 2 OF 2" after log-file indication " ----------Correcting NCS rotamer outliers---------- Set U 69 GLU to tp10 rotamer" followed by the error message : "Traceback (most recent call last): File "/usr/local/phenix/phenix-dev-1391/build/intel-linux-2.6-x86_64/../../phenix/phenix/command_line/refine.py", line 11, in <module> command_line.run(command_name="phenix.refine", args=sys.argv[1:]) File "/usr/local/phenix/phenix-dev-1391/phenix/phenix/refinement/command_line.py", line 161, in run call_back_handler=call_back_handler) File "/usr/local/phenix/phenix-dev-1391/phenix/phenix/refinement/driver.py", line 1659, in run ncs_manager = self.ncs_manager).result File "/usr/local/phenix/phenix-dev-1391/phenix/phenix/refinement/strategies.py", line 170, in __init__ ion_placement_manager = ion_placement_manager) File "/usr/local/phenix/phenix-dev-1391/phenix/phenix/refinement/macro_cycle.py", line 66, in __init__ self.call(self.ncsrot, "NCS rotamer correction") File "/usr/local/phenix/phenix-dev-1391/phenix/phenix/refinement/macro_cycle.py", line 101, in call func(prefix = prefix) File "/usr/local/phenix/phenix-dev-1391/phenix/phenix/refinement/macro_cycle.py", line 146, in ncsrot log = self.log) File "/usr/local/phenix/phenix-dev-1391/phenix/phenix/refinement/misc.py", line 89, in ncs_rotamer_update log=log) File "/usr/local/phenix/phenix-dev-1391/cctbx_project/mmtbx/torsion_restraints/torsion_ncs.py", line 1111, in fix_rotamer_outliers key=key) File "/usr/local/phenix/phenix-dev-1391/cctbx_project/mmtbx/torsion_restraints/rotamer_search.py", line 178, in search assert rotamer == cur_rotamer AssertionError" I have been using built phenix-dev-1391 (I also checked phenix version 1.8.2-1309 or built dev-1436, they crashed as well) x86_64-fc3, in a machine running Ubuntu 10.04.4 LTS with Python 2.6.5.

distance threshold for special positions?
by Alastair Fyfe 31 Jul '13

31 Jul '13

I'd be grateful for pointers to documentation/source regarding phenix.refine's criterion for flagging an atom's coordinates as coinciding with a special position. For shelxl I noticed a distance cutoff of 0.02 to the symmetry equivalent position seems adequate for the data I'm working with. For phenix.refine the threshold is higher but I haven't found documentation for the cutoff used. thanks, Alastair Fyfe

proteins sequence for phenix
by LISA 26 Jul '13

26 Jul '13

Dear All, Phenix will ask for the protein sequence when we create a new project. I try to solve my complex by the Autosol in phenix with proteins sequence. My complex contains 2 molecule A and 3 molecule B. How can I give the sequence in phenix? will it should be: >A .................................................................................................................. >B .............................................................................................................................. or >A .................................................................................................................. >A .................................................................................................................. >B .............................................................................................................................. >B .............................................................................................................................. >B .............................................................................................................................. Thank you. Lisa
