iNEXT / X-rays (and more) notes
by Anastassis Perrakis 24 Mar '16

24 Mar '16

Dear all, I want to bring to everybody’s attention a few things about iNEXT Synchrotron Access proposals, as they seem to surface up often. - “BAG” proposals are possible, but only when under a common translational scientific theme; not simply based on lab proximity. - iNEXT funds complete projects, both beam time and travel; arguing that "we have beamtime, just give us travel money” will likely get your proposal rejected. - Please be clear to state that you have crystals and/or justify what the SAXS experiments are answering. Please keep in mind a specific difference from past schemes: you do not need to submit a separate proposal to the synchrotron site to get beam time! A successful iNEXT application will be received by the site(s) you apply for, and only safety data will be requested and a technical review will be done based on the existing application. We are looking forward receiving your applications for high-end synchrotron data collection, but also for : 1. Structural Audit (including crystallisation trials and SAXS: please advertise to your biochemistry colleagues!) 2. Macromolecular Interactions (Biophysics for quantitative characterising) 3. Cryo-EM sample optimisation (if you have negative stain images) 4. High-end NMR data collection 5. High-resolution EM (if you have good cryo conditions, and also for tomography and CLEM) … and more modalities to come soon! http://www.inext-eu.org/access/ <http://www.inext-eu.org/access/> On behalf of the iNEXT team, Tassos

.Trash_UID error message
by Michael Weyand 23 Mar '16

23 Mar '16

Dear experts, our Phenix installation suffers on a nasty error message concerning permission problems on /data/.Trash_UID (/data is our mount point of a NFS share) when deleting a certain job from the history. Of course, no user has write access to the top folder / mount point! And I know that is might be an OS problem with NFS mounted disks (well known for Ubuntu systems). But we have an openSuSE with KDE, not GNOME. I also checked the Phenix preferences for an option, but was not successful. Is there any way to get rid of this message or better to say not deleting to .Trash folder? Thanks in advance, Michael

The 2016 Diffraction Methods in Structural Biology Gordon Research Conference
by Edward Snell 22 Mar '16

22 Mar '16

Dear All, This is not Phenix related but we do see a lot of representation from Phenix developers and users at this conference. The 2016 Diffraction Methods in Structural Biology Gordon Research Conference (GRC) will be held at Bates College in Maine from July 17,to July 22nd 2016 - immediately before the American Crystallography Association Annual Meeting. The theme of this year's conference is "Probing the Structure and Dynamics of Macromolecules" and the conference celebrates its 40 year anniversary. Current details are available at https://www.grc.org/programs.aspx?id=11655. Program details are below, it promises to be an exciting. Arwen Pearson (co-chair) and I would like to invite you to consider attending the conference. Topics to be covered include new instruments and opportunities on the horizon, methods to improve maps and models, complementary approaches, resolving dynamics, the interplay between XFEL and synchrotron, new diffraction developments, and structure beyond Bragg diffraction. Many of the worlds experts in these areas will be at the meeting and we encourage the participation of every level of expertise to cross-pollinate the field. We will also have an opportunity for selected poster presenters to present talks at the meeting. Applications for the conference are now being accepted and will continue to be accepted until we are full. >From a personal perspective this is probably one of the best meetings for those interested in the nuts and bolts of diffraction methods. It is also a unique opportunity to meet many of the key members of the field. It is a friendly and productive conference, and an exciting one in terms of getting a preview of the future. We encourage you to attend, take part in great science, and also interact in a less formal social and sometimes sporting atmosphere. This will also be the second year that a related Gordon Research Seminar (GRS) is run. This is a meeting organized for and by post-docs and graduate students. Drs. Rike Mueller-Werkmeister and Bradely Hintze are organizing this with details at https://www.grc.org/programs.aspx?id=16486. We strongly encourage laboratories with an interest in Diffraction Methods in Structural Biology to support their students in attending both the GRS and the GRC with the GRS serving as a useful introduction to the larger conference. We are still raising funds for the GRS and GRC, in particular to enable younger scientists to attend. We are grateful and thank those who have supported us so far, and also those that are in the process of doing so. We are actively looking for further sponsorship. Summer is a full time for meetings but this is going to be a very worthwhile one. Please pass this onto interested colleagues.

Set up phenix and rosetta for phenix.rosetta_refine
by Yonglin Hu 17 Mar '16

17 Mar '16

Hello List, I would like to perform phenix.rosetta_refine on a structure. I understand that to use this program, I need to set up phenix and rosetta installations separated from those used in MR_Rosetta. I installed the most recent phenix and rosetta and followed the online documents, but when I tried to run "rosetta.build_phenix_interface", the program failed immediately with the following error messages: False scons: Reading SConscript files ... Running versioning script ... fatal: Not a git repository (or any of the parent directories): .git Done. (0.0 seconds) Could not find platform independent libraries <prefix> Could not find platform dependent libraries <exec_prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] ImportError: No module named site CalledProcessError: Command '['./update_options.sh']' returned non-zero exit status 1: File "/usr/local/rosetta-refine/rosetta/main/source/SConstruct", line 172: main() File "/usr/local/rosetta-refine/rosetta/main/source/SConstruct", line 163: SConscript("SConscript", "build") File "/usr/local/rosetta-refine/rosetta/main/source/external/scons-local/scons-local-2.0.1/SCons/Script/SConscript.py", line 614: return method(*args, **kw) File "/usr/local/rosetta-refine/rosetta/main/source/external/scons-local/scons-local-2.0.1/SCons/Script/SConscript.py", line 551: return _SConscript(self.fs, *files, **subst_kw) File "/usr/local/rosetta-refine/rosetta/main/source/external/scons-local/scons-local-2.0.1/SCons/Script/SConscript.py", line 260: exec _file_ in call_stack[-1].globals File "/usr/local/rosetta-refine/rosetta/main/source/SConscript", line 28: subprocess.check_call(["./update_options.sh"]) File "/usr/local/rosetta-refine/phenix-dev-2328/base/lib/python2.7/subprocess.py", line 540: raise CalledProcessError(retcode, cmd) These messages are not very informative and I don't know what to do next.

on b-factor refine
by Smith Liu 15 Mar '16

15 Mar '16

Dear All, I just read a paper on phenix refine, which contains content "B-factor refinement (two groups per residue) ". Here the "two groups per residue" should be accomplished by the phenix command line rather than the GUI, right? And if right, will you please let me know the command for "two groups per residue" for B-factor refine? Smith

Real space difference maps?
by Oliver Clarke 15 Mar '16

15 Mar '16

Hello, is there any possibility of (or current plan for) including the capacity in a future PHENIX release to calculate a residual map automatically after phenix.real_space refine, (i.e. simulating a map from the model incorporating corrections for B-factor variation and calculating a difference map with the experimental map)? This would be very convenient when building into EM maps. Cheers, Oli
