Phaser problems
by Yarrow Madrona 18 Dec '11

Hello, Lately I have been having some trouble with phaser MR. For some reason even if I get a complete solution, it involves molecules from two different unit cells and it one case it picked up a symmetry related molecule as a crystallagraphic dimer. Recently I re-ran jobs from a sucessful run (over a year ago) in Phaser 2.1.4 where I get 4 molecules in the asymetric unit with plausable contacts that refined very well. Recently, however, I have re-run the job with the same search molecule and settings (all default). Although I get a solution, it involves molecules apparently from two asymetric units. The dimers formed are not the same contacts as what was seen in the earlier phaser run with Phaser 2.1.4. However if you turn on the symetry related molecues the tight crystallagraphic dimer seen previously shows up between one molecule and a symmetry mate. Has anyone had experiences like these recently with phaser? BTW my search model is 99% identical to my molecule (only one residue difference). Thanks. -Yarrow -- Yarrow Madrona Graduate Student Molecular Biology and Biochemistry Dept. University of California, Irvine Natural Sciences I, Rm 2403 Irvine, CA 92697

Dear Nat, I changed the .py file as you suggested, and for the moment, it seems to work. Thanks!

GUI MR_Rosetta without explicit search model?
by Gohlke, Ulrich 16 Dec '11

16 Dec '11

Dear colleagues, I am trying to set up an MR_Rosetta run using the GUI of Phenix 1.7.3. Unlike the command line version, it doesn't seem to accept either Robetta fragment files or alignment files from the hhpred server as the sole input but it keeps on asking for a pdb-file as search model. Is this behaviour intended or am I missing something?

Dear Phenix Users, I am trying to compile rosetta mr on my fedora 10 computer: http://www.phenix-online.org/documentation/mr_rosetta.htm#anch35 Compared to the instructions % tar xzf rosetta3.2_Bundles.tgz did not work for me, instead I run % tar xvf rosetta3.2_Bundles.tgz and subsequently % tar xvf BioTools-3.3.tgz % tar xvf protocol_capture-3.3.tgz etc etc >From the rosetta_source directory as an ordinary user (not root) I run: % python scons.py -j2 bin mode=release The compilation runs for a while but finally I got the termination message below. What should I try next?

Reflection file woes phenix/ccp4/PDB
by Machius, Mischa Christian 16 Dec '11

16 Dec '11

Y'all, While depositing a structure, the PDB 'complained' about my structure-factor file, saying they don't contain R-free flags or are otherwise incomplete. The comment was prompted by their Refmac R-factor test failing. The structure-factor file I submitted came from phenix.refine (xxx_data.mtz). I am using version 1.7.3-928. Indeed, using this file in CCP4 fails with the message: "CCP4MTZfile: Mtz column type mismatch: I-obs(+) K-J CCP4MTZfile: Mtz column type mismatch: SIGI-obs(+) M-Q" The file contains anomalous data. I have no problems with files that do not contain anomalous data. Needless to say that Phenix uses the structure-factor file just fine when reading it back into, say, its validation utility. When I use iotbx.reflection_file_reader, I cannot detect any anomalies. I am at a loss as to how to resolve this issue. I would like to deposit the data as prepared by Phenix so that the PDB tools can use them. Anybody ran into this issue before? Any ideas for how to resolve it? Many thanks in advance! MM

Re: [phenixbb] Compilation problem rosetta MR on Fedora 10
by Eugene Valkov 15 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 15 Dec '11

15 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 } } }
