Berkeley Server Downtime (3/23 - 3/24)
by Billy Poon 25 Mar '17

25 Mar '17

Dear all, On Thursday, March 23, our servers will be shut down starting at 5:00 pm Pacific for some emergency electrical work near our building. We expect that the servers will be available the next day (3/24) by 1:00 pm Pacific. There is a possibility that the outage will last longer. This will affect, - The Phenix web site (http://phenix-online.org/) - The DIALS West web site (http://dials.lbl.gov/) - The CCI web site (http://cci.lbl.gov/) - The Structural Biology Technology Portal (http://technology.sbkb.org/) Bug reports and emails requesting help should be queued and we will receive them once the servers are back online. We apologize for any inconvenience and the short notice. -- Billy K. Poon Research Scientist, Molecular Biophysics and Integrated Bioimaging Lawrence Berkeley National Laboratory 1 Cyclotron Road, M/S 33R0345 Berkeley, CA 94720 Tel: (510) 486-5709 Fax: (510) 486-5909 Web: https://phenix-online.org

options in phenix.merging_statistics
by Murpholino Peligro 24 Mar '17

24 Mar '17

Hello. I was wondering what is the normal situation where one should click the boxes marked as "Keep anomalous pairs separate in merging statistics" (option1) and/or "Use internal variance of the data in the calculation of the merged sigmas" (option2)? I am asking because it looks like it is detrimental to the statistics, as you can see in the file attached (CSV file with 4 columns for no options, option1, option2 and option1&2). Thanks in advance.

Hi, is it possible to do ensemble refinement in phenix with just one domain? (and e.g. fix the other) Doens seem so? Thanks, Tommi

Error running phenix.rosetta_refine tests with Rosetta 3.8
by Oliver Clarke 21 Mar '17

21 Mar '17

Hi, Phenix rosetta refinement worked with previous versions of rosetta and phenix, but with the latest Rosetta version (3.8) and latest phenix nightly I get a crash when running rosetta.run_tests after building the rosetta phenix interface, which runs a test run of phenix.rosetta_refine. It gets to the stage of generating initial models and then crashes - see attached log. Ideas for a fix welcome! Cheers Oli

difference map for cryo-EM (cryo-EM map minus model map)
by Pavel Afonine 17 Mar '17

17 Mar '17

For those practicing cryo-EM and tending to use Phenix nightly builds, as well as in response to a recent post (Re: [phenixbb] difference map based on the cryo-EM map): Next Phenix nightly build (dev-2612 and up) will have a command line tool to compute map-model real-space difference maps. One map is computed in real space: cryo-EM map minus model calculated map; it is locally scaled in some complex way to account for local variations and possibly poorly refined B-factors. In terms of reciprocal space it is an analog of: (F_obs, Phase_obs) - (F_calc, Phase_calc). The other map is computed using both spaces, and is analog of (F_obs-F_calc, Phase_obs); here no model phase is involved. I'm not sure which one of the two is better. Both maps are useful to locate ligands or yet not built pieces of the model (very much like in crystallography). Current limitations: - no GUI; - map must have origin at (0,0,0); - output file name can't be changed. To use: phenix.real_space_diff_map model.pdb map.ccp4 resolution=3.9 which will output two maps: map_model_difference_1.ccp4 and map_model_difference_2.ccp4 . If proving ligand is the purpose to compute this map, then obviously it should not be present in model.pdb. In future (once fully tested) this will be integrated into phenix.real_space_refine. The tool is 10 hours old and tested on just one model (5l4g, emd_4002.map), so bugs are not unexpected. Any feedback is welcome! All the best, Pavel

Re: [phenixbb] phenix.erraser and PHENIX_ROSETTA_PATH; problem fixed.
by Mooers, Blaine H.M. (HSC) 16 Mar '17

Hi Andy, Thank you for the clarification! Yes, I was wrong. There is still a tools subdirectory at the top level. I installed the latest version of Rosetta from source. This is version 3.8, the Feb. 25th, 2017 release. The rosetta\_options.py file is in the same location: main/source/src/apps/public/ERRASER. Following up on your suggestion, I edited the file erraser.py in /Applications/phenix-dev-2686/modules/phenix/phenix/erraser by replacing line 543 with the following: file_path = os.path.join(params.directories.rosetta_path, 'main/source/src/apps/public/ERRASER') Phenix.erraser now runs.

phenix.erraser and PHENIX_ROSETTA_PATH

Dear phenixbb, This is a question about phenix.erraser. I had it running in March 2016, but it no longer works. I am using phenix-dev2686.

Open Postdoctoral Position at Oak Ridge National Laboratory
by Paul Adams 11 Mar '17

11 Mar '17

Dear Colleagues, on behalf of my colleagues I’d like to bring to your attention an open postdoctoral associate position at Oak Ridge National Laboratory (ORNL): Summary - To maximize the information obtained for diffraction experiments for structural biology, data processing methods need to be improved for marginal, weak data and also for reflection overlap. Methods will be developed that make use of knowledge about the atomic model to inform data processing methods so that reflections can be successfully deconvolved. A novel technique for full profile single crystal structure refinement will be developed. This work will be performed through a National Institutes of Health (NIH) funded consortium between ORNL and Lawrence Berkeley National Laboratory (LBNL) to develop a broad range of computational tools for macromolecular neutron crystallography. The aim of this consortium is to address the need for new computational tools and methods to deal with the increasing number of neutron macromolecular structures being determined and their increasing size and complexity. These tools will be developed in close collaboration with the PHENIX program, a NIH funded consortium between several groups. Interested candidates should visit: https://www.ornl.gov/careers Job Posting: Postdoctoral Research Associate - Computational Methods for Integrating Protein Crystallography Data / NB50615195 https://recruiting-internal.ornl.gov/sap/bc/erecruiting/posting_apply?param… -- Paul Adams Division Director, Molecular Biophysics & Integrated Bioimaging, Lawrence Berkeley Lab Division Deputy for Biosciences, Advanced Light Source, Lawrence Berkeley Lab Adjunct Professor, Department of Bioengineering, U.C.

Please attend a workshop on Measurement and Interpretation of Diffuse Scattering in X-Ray Diffraction for Macromolecular Crystallography
by Robert Sweet 09 Mar '17

09 Mar '17

Driven by recent advances in this field we will hold a workshop to discuss it. The workshop will be on Monday, May 15, 2017 at Brookhaven Nat'l Laboratory, and will be affiliated with the 2017 Users' Meeting for NSLS-II and the Center for Functional Nanomaterials. The current draft agenda is on-line here: http://usersmeeting.ps.bnl.gov/workshops/workshop.aspx?year=2017&id=136 Registration for the Workshop and Users' Meeting is here: http://usersmeeting.ps.bnl.gov/registration/?year=2017 A description of the workshop is below. The Organizers: Robert Sweet (NSLS-II, BNL), Michael Wall (LANL), Nozomi Ando (Princeton University), James S. Fraser (University of California, San Francisco), George N. Phillips, Jr. (Rice University) For answers to questions, please contact Wall: mewall(a)lanl.gov or Sweet: sweet(a)bnl.gov Description: X-ray diffraction from macromolecular crystals includes both sharply peaked Bragg reflections and diffuse intensity between the peaks. The information in Bragg scattering reflects the mean electron density in the unit cells of the crystal. The diffuse scattering arises from correlations in the variations of electron density that may occur from one unit cell to another, and therefore contains information about collective motions in proteins. A major focus of the workshop will be to provide a roadmap to the acquisition of reliable data by surveying measurement methods and discussing the increase in measurement accuracy enabled by improved detectors, experimental methods, and data integration. Missing from recent results is real information about the behavior of the molecules being studied that would guide the thinking of biochemists and biologists. To discuss these and their relative merits will be a second major focus of the workshop. The charge to this workshop will be to provide a roadmap to efforts that will provide the biological understanding we believe is hidden in the data. ========================================================================= Robert M.
