phenix.molprobity geo
by Paul Emsley 05 Mar '21

05 Mar '21

Hello, I'd like to compare the restraints generated by Coot to the validation provided by molprobity. When I run phenix.molprobity on my model, it gives me (amongst other things) this: ----------------------- Histogram of nonbonded interaction distances: 1.87 - 2.42: 526 2.42 - 2.96: 3217 2.96 - 3.51: 3639 3.51 - 4.05: 5026 4.05 - 4.60: 6847 Nonbonded interactions: 19255 Sorted by model distance: nonbonded pdb=" O LEU A 21 " pdb=" H GLY A 26 " model vdw 1.874 1.850 nonbonded pdb=" H ILE A 71 " pdb=" O TYR A 80 " model vdw 1.920 1.850 nonbonded pdb=" H GLY A 34 " pdb=" O GLU A 54 " model vdw 1.925 1.850 nonbonded pdb=" O ILE A 71 " pdb=" H TYR A 80 " model vdw 1.937 1.850 nonbonded pdb=" HE ARG A 40 " pdb=" HG1 THR A 76 " model vdw sym.op. 1.955 2.100 -x+3/2,-y,z+1/2 ... (remaining 19250 not shown) NOTE: a complete listing of the restraints can be obtained by requesting output of .geo file. -------------------------- I don't understand this lilst. Should I be concerned by those interactions? Which of these atom pairs are contributing to the clashscore? Perhaps the details are in the .geo file? How do I get a .geo file? I googled, I didn't find the answer. How could I have found the answer without asking here? Thanks, Paul.

on rosetta installation for phenix
by Smith Lee 02 Mar '21

02 Mar '21

Dear All, I have tried to install Rosetta for phenix use based on the guide in https://www.phenix-online.org/documentation/reference/rosetta_install.html. After the "tar xzf..." command, I added the directory for the installed rosetta (something like "export PHENIX_ROSETTA_PATH=/your-path-to-rosetta-here/") to my .bashrc (and in fact I also have added into /bash_profile) and sourced it. For the final step to build the interface for rosetta_refine, as for my gcc version is 8.3.1, I have deleted the original site.settings in the directory ${PHENIX_ROSETTA_PATH}/main/source/tools/build/, and exactly copied the content in https://www.phenix-online.org/documentation/extras/site.settings and save it as site.settings in the directory ${PHENIX_ROSETTA_PATH}/main/source/tools/build/. Command "nproc" displays 12, then I run "rosetta.build_phenix_interface nproc=12". In the running step for the above command, I remember it asked me "whether to install "sed" (I do not what is "sed" for), I answer "y" and "enter", it seems like the computer stopped. I opened another terminal, and all commands like "ls","cd" failed to work. I restarted the computer, but I cannot log into my centos username account anymore. I restarted the computer by initiating the centos secure start system, and deleted the export directory for the rosetta from the .bashrc and .bash_profile. In this way I restarted the computer and I can log into my centos user name account as usual. But as you know, my rosetta still did not work. Thus, will you please advice what is wrong for my installation fof the rosetta (for phenix use) and how to make it workable? I am looking forward to getting your reply. Best wishes, Smith

executing Phenix in a python script on a Windows OS
by Muriel Gelin 02 Mar '21

02 Mar '21

Dear Phenix community, I wrote a python script to automate the processing of our data with Phenix. I'm not a developer by profession, but a crystallographer, and write scripts usually under Linux. My colleagues working under Windows asked me to share my script. I managed to run a simple python script under windows, no problem. But for a script that executes Phenix, it's not so easy (for me). Under Linux, I manage to source phenix_env.csh, but under Windows what is the command to setup Phenix in order to simply use phenix.refine or phenix.xtriage in my script? All I can find is this page https://www.mrc-lmb.cam.ac.uk/public/xtal/doc/phenix/install-setup-run.html but I don't think it answers my question. Thank you in advance for your help!

The position: The position seeks to strengthen ongoing activities in the laboratory of Bjørn P. Pedersen on structure, related to the function and mechanism of plant hormone-transporting membrane proteins as defined by the ERC project MUM-GROW (pedersenlab.dk). Exact project will be shaped out in dialogue with top runners. The laboratory's interest is the interplay between structure and function of transmembrane transport processes with a focus on metabolite uptake systems, and the methods uses are primarily crystallography and cryo-EM. The group is part of the Section of Structural Biology at Aarhus University. The candidate: A successful candidate has a relevant Ph.D. degree and a solid and documented background in structural biology, biochemistry and/or biophysics. Experience with membrane protein expression and purification is favored, and the candidate must demonstrate an ability and interest to work with membrane proteins with a structural aim. Applicants should be ambitious, show strong collaborative skills, and be able to take initiatives and responsibility within the work environment. The successful candidate is offered: - access to a well-developed research infrastructure. - a research climate inviting lively, open and critical discussion within and across different fields of research. - a working environment with teamwork, close working relations, network activities among young scientists and social activities. - a workplace characterized by professionalism, equality and a healthy work-life balance. The city: In Aarhus you have easy access to beautiful nature, an exciting culture and city life as well as a safe environment for children - a great place for the whole family. The city of Aarhus has everything you need: exciting national and international jobs, delightful residential areas, a rich cultural life, and beautiful surrounding landscape of woods and coastline that make Aarhus a wonderful place to live and work.

EMBO workshop on Molecular Neurobiology
by Janssen, B.J.C. (Bert) 25 Feb '21

25 Feb '21

Dear all, a gentle reminder of the upcomingEMBO workshop on "Molecular Neurobiology", a virtual meeting taking place on 21-25 May 2021. The deadline for registration, 28 February, is approaching fast. Only four days left. The virtual meeting brings together world leading scientists, group leaders and young researchers with a keen interest in the latest science occurring at the interfaces of structural biology, biophysics, molecular & cellular imaging and neuroscience. Given its cross-disciplinary nature, the meeting presents a broad overview of molecular neurobiology, ample opportunities for discussions and a sneak peek into the latest developments. See http://meetings.embo.org/event/20-molneuro for more information and application guidelines. Best wishes, Bert Bert Janssen Bijvoet Center for biomolecular research Utrecht University Padualaan 8, 3584 CH, Utrecht
