mr_rosetta - homology search with hhr file - Cannot contact EBI DbFetch
by iulek＠interponta.com.br 07 Jun '11

07 Jun '11

Dear all, I would like to use mr_rosetta with homolgy search. I followed the instructions at http://www.phenix-online.org/documentation/mr_rosetta.htm , generated the hhr and the fragment files, but at submitting the job I receive the message: ******************* ERROR ENDING *************** Cannot contact EBI DbFetch service ******************* ERROR ENDING *************** after both loading the file 3800765_mod_ed.hhr and generating the log file mr_model_preparation.log. Concerning this problem, I saw http://www.phenix-online.org/documentation/faqs.htm#anch8 . But I am not behind a proxy and even disabling completely the firewall, the message still appears. Maybe this is more linux related, I use openSuSE 11.4. One workaround would be that I write a script to wget the pdb files (listed in .hhr) and select the due chains, putting these in a certain location and indicating in my script where they are. But I am a kind of confused, might search_models= do this. I am not sure I could use a hhr file together with it. Anyway, this might be a desirable solution for me yet I use to run my stuff in a laptop which goes around by. Thanks, Jorge

HI all, In my structure, there is a double conformation residue and on conformation is coordinated to a metal. I use phenix.metal_coordination to generate a elbow.edits file.

meaning of nproc in mr_rosetta
by Miguel Ortiz Lombardía 07 Jun '11

07 Jun '11

Dear Phenix developers, Could you elaborate on the meaning of "nproc" in phenix.mr_rosetta? I tried unsuccessfully to find out in the docs. Please, let me know if I missed something. I sent out a master job to an SGE queue engine, having set nproc=64. At this moment I find 168 jobs submitted and running and the total number of processors in use seems to be around 120. Better understanding of the meaning of nproc would help with the allocation of resources.

The SASTBX webserver
by Peter Zwart 03 Jun '11

03 Jun '11

Dear All, I would like to advertise our online server featuring some basic SAXS analyses tools. The website http://sastbx.als.lbl.gov/cgi-bin/index.html has functionality for 1. Model intensity calculation (using a Spherical Harmonic Expansion; sastbx.she ) 2. Shape determination (or better: Shape Recovery; sastbx.shapeup) 3. Model alignment (sastbx.zalign) The applications we have developed are build using the SASTBX, an extension of the CCTBX (http://cctbx.sf.net) framework, dedicated to the analyses of SAXS data. The model intensity calculation engine uses an approach similar to CRYSOL and (in our hands) provides model SAXS data of a similar quality as FOXS and CRYSOL. The shape recovery procedure (shapeup) provides an estimate of the shape typically within 1 minute without the need for preprocessing the data (i.e. just feed it your background subtracted SAXS curve and nothing more). You can provide a known model as well for comparison. Some example shape recovery results can be found here: http://sastbx.als.lbl.gov/grant/shapeup/summary.html The examples were prepared utilizing data provided by Edward Snell and coworkers (Grant, T. D., Luft, J. R., Wolfley, J. R., Tsuruta, H., Martel, A., Montelione, G. T. and Snell, E. H. (2011), Small angle X-ray scattering as a complementary tool for high-throughput structural studies. Biopolymers, 95: 517–530). Feel free to contact me or Haiguang Liu (HGLiu(a)lbl.gov) if you encounter any problems or have questions.

omit map
by Desi Mail 03 Jun '11

03 Jun '11

Hi everybody, I would like to calculate the omit map around the ligand. I followed the documentation http://www.phenix-online.org/documentation/autobuild.htm#anch159 But the 2Fo density around the ligand is very poor. Any help is appreciated. Thanks Mary Make a SA-omit map around atoms in target.pdb phenix.autobuild data=data.mtz model=coords.pdb omit_box_pdb=target.pdb composite_omit_type=sa_omit Coefficients for the output omit map will be in the file resolve_composite_map.mtz in the subdirectory OMIT/ . An additional map coefficients file omit_region.mtz will show you the region that has been omitted. (Note: be sure to use the weights in both resolve_composite_map.mtz and omit_region.mtz).

Diamond Light Source phase III beamline proposal - call for support.
by Johan Turkenburg 03 Jun '11

03 Jun '11

Many of you will already have seen the request for Expressions of Interest for the Diamond phase III proposal for "A versatile microfocus beamline with an in-situ side station for macromolecular crystallography at DIAMOND". As one of the co-proposers I would like to urge you to support this proposal and write a letter to this effect. We need as many as possible! Details of the proposal can be found here, with a link where your letter of support can be uploaded: http://www.diamond.ac.uk/Home/Beamlines/PhaseIII/ExpressionsofInterest.html You may already have been contacted by other colleagues in the MX community but this is of high importance to the structural community as a whole, and we especially invite our international colleagues to provide support for this initiative. To help us collate these EOI's and comment on any additional feedback you may have, we would ask you to do this by June 8th. Johan Dr. Johan P.

elbow question
by wtempel 03 Jun '11

Dear colleagues, am I alone in thinking that in my example phenix.elbow gave me more than what I was asking for, specifically atom H11 attached to sulfur? Is it added by elbow, or does it originate from the "--chem=tpp" input? Best regards, Wolfram Tempel command line: phenix.elbow --chem=tpp --mogul phenix version: 1.7.1-743
