Re: [phenixbb] Compilation problem rosetta MR on Fedora 10
by Eugene Valkov 16 Dec '11

Hi Martin, I had encountered an issue with building Rosetta 3.2.1 on Ubuntu 11.04, specifically that SCons could not compile it because it used gcc 4.1 libraries, whereas there was gcc 4.4 installed. Could you check what version of gcc you have installed on your Fedora box? If it is the compiler issue then there are some workarounds documented on Rosetta forums: https://www.rosettacommons.org/node/2274 These worked for me, but you have to hack around in code a bit to make it happen.

loosening constraints on water addition
by Crystal VanderZanden 16 Dec '11

16 Dec '11

I'm trying to adjust the parameters on the water picking to allow for more waters to be found. I tried creating a solvent.params file with the code below, then I increased and decreased the primary map cutoff. When I ran the water picking command with the solvent.params file, it actually decreased the number of waters found, both at the high and low primary map cutoff. Does anyone know what I can do to relax the water finding criteria so more waters will be found? Thanks, Crystal refinement { ordered_solvent { low_resolution = 2.8 b_iso_min = 1.0 b_iso_max = 50.0 b_iso = 25.0 primary_map_type = mFobs-DFmodel primary_map_cutoff = 3.0 secondary_map_and_map_cc_filter { cc_map_2_type = 2mFobs-DFmodel } } peak_search { map_next_to_model { min_model_peak_dist = 1.8 max_model_peak_dist = 6.0 min_peak_peak_dist = 1.8 } } }

phenix.superpose_pdbs and nucleic acids.. does it work?
by Francis E Reyes 15 Dec '11

15 Dec '11

Hi phenixer's. I need to do a superposition of two pdbs. I guess phenix.superpose_pdbs is my jiffy but it doesn't seem to work for nucleic acids (tried selection = 'name P' or selection = 'all'). LSQKAB seems to have the same limitation. They are the exact same PDBs (1 to 1 atom/residue mapping) but just shifted and rotated relative to the other. I need a superposition or the transformation matrix for all atoms. Traceback (most recent call last): File "/usr/local/phenix-1.7.1-743/phenix/phenix/command_line/superpose_pdbs.py", line 450, in <module> run(args=sys.argv[1:]) File "/usr/local/phenix-1.7.1-743/phenix/phenix/command_line/superpose_pdbs.py", line 434, in run m = manager(params.extract(), log) File "/usr/local/phenix-1.7.1-743/phenix/phenix/command_line/superpose_pdbs.py", line 171, in __init__ selection_moving = self.selection_moving) File "/usr/local/phenix-1.7.1-743/phenix/phenix/command_line/superpose_pdbs.py", line 306, in _alignment "bugs(a)phenix-online.org for help.") RuntimeError: Failed to identify corresponding atoms from sequence alignment. This is probably a bug - contact bugs(a)phenix-online.org for help. I may just strip it down to phosphate's and rename the residues to ALA but a quick phenix jiffy would be great. Thanks! F --------------------------------------------- Francis E.

on residue bond deviation
by Dialing Pretty 15 Dec '11

15 Dec '11

Dear All, After a key step refinement byPhenix refine, I find there are 2 residues (total about 450 residues) with bad angles as analyzed by MolProity (deviation ratio 0.46%, goal is 0.1% ), both of the 2 residues are Pro, and both of the deviation angles are C-N-CA. Will you please give the comment on what do the 2 deviations mentioned above mean for my whole protein structure, or should I continue to refine my protein structure? I am looking forward to getting your reply. Dialing

on the input file for the Phase and build
by Dialing Pretty 15 Dec '11

15 Dec '11

Dear All, For the Phenix Phase and build, the input mtz file is the scala mtz file, and the ouput mtz file will be the mtz file with phase, is this correct? I am looking forard to getting a reply from you. Cheers, Dialing

strange MR problem
by intekhab alam 13 Dec '11

13 Dec '11

Hi All I have a 3.0A dataset of a protein-protein complex. I used one of the protein structure solved previously as a template and used phaser in CCP4 as well as in phenix. I used the sca file in phenix which gave a solution with 6 monomers in ASU which are packed as a hexamer. In ccp4 phaser i used the converted .mtz file which gave 6 molecules in ASU but with a different packing. In both the cases map fits well in the model and there is some extra density that may correspond to second protein partner of the complex molecule. when i tried to use the MR solution generated in phenix with the mtz file from ccp4 the model shows a lot of clashes. what kind of approach should i take so as to resolve this ambiguity.

ncs_average output map
by Ursula Schulze-Gahmen 13 Dec '11

13 Dec '11

I am puzzled about my ncs-averaged output map. I determined the ncs relation using phenix.find_ncs with pdb and mtz input. The program finds 2 NCS groups with 3 molecules each and the rmsds are low. I then read in the ncs_spec file and an mtz file with map coefficients into phenix.ncs_average. I used the FOFCWT, PHFOFCWT coefficients. The output map seems cleaner than the unaveraged map and shows some of the same features, but the density around the 3 molecules is not identical. 2 of them look very similar, but the density around one of them is somewhat different. How is this possible if the map is averaged? Thanks for any suggestions or explanations.
