Speeding direct summation ?
by Clement Degut 02 Nov '18

02 Nov '18

Hi, I have (very) high resolution data, for which direct summation method seems to give significantly better map than FFT (i.e. visible hydrogen vs not). My main problem is that refinement got from quite slow, to barely not really possible to handle slow. I have 2 question from that : Am I looking at an artifact ? Meaning should at this resolution (0.84A for CC1/2 at 30% and good overall statistics) see extreme difference between map quality with direct summation vs FFT ? And if yes, can I speed the process compiling phenix with openMP on our cluster ? Or shoul I just become patient ? Many thanks Clément

02 Nov '18

Postdoctoral Fellow, Takagi Laboratory (https://medicine.iu.edu/research/faculty-labs/takagi/), Department of Biochemistry and Molecular Biology Indiana University School of Medicine We are looking for a highly motivated postdoctoral follow with a background in structural biology (X-ray crystallography, cryo-EM), to work on NIH-funded projects studying multi-protein complexes involved in eukaryotic transcription regulation. Who We Are: My laboratory is interested in understanding the mechanisms of assembly, structure and function of large multi-protein complexes -“molecular machines” - involved in eukaryotic gene regulation, utilizing both cryo-EM and X-ray crystallography. We are particularly interested in the Mediator complex in both yeast and humans. We believe that development and implementation of novel technologies is the key to unlocking the mysteries of how highly complex molecular machines (e.g. Mediator) function. Therefore, our overall research objective is two-fold: (i) development of novel technologies for studying multi-protein complexes, and (ii) application of these technologies to elucidate the structure and function of the Mediator complex. In addition, we have developed a novel technology for producing pure preparations of difficult-to-express proteins and protein complexes, which has enabled several exciting ongoing projects with outstanding collaborators, including work on: plant RNA polymerases, DNA helicases, DNA repair complexes, RNA editing complex, and insulator complex. What We Offer: State-of-the art protein and protein complex expression technologies (patent pending) enabling expression of difficult-to-express, problematic proteins and protein complexes Accessibility to crystallization drop-setting robots, home X-ray sources, Synchrotron data collection at the Advanced Photon Source (APS) at Argonne National Laboratory (within a 3 hour drive from our lab), as well as electron-microscopy (EM) facility: Titan Krios, Talos Artica, and JOEL-FS3200 A one-on-one mentoring opportunity by which a postdoctoral fellow can learn the craft of designing research strategy, preparing compelling grant proposals, and paper-writing and presentation skills The opportunity to work with multiple outstanding collaborators Who Should Apply: This position could be a great fit for you if: you have the expertise and experience in X-ray crystallography, and want to apply such skills toward structure determination of highly complex multi-protein complexes you are interested in learning and developing for the cutting-edge protein complex engineering and expression technologies you would like to extend your skill sets to cryo-EM you are self-confident and can communicate with the PI, other lab members, and collaborators with ease, and enjoy discussing research results and how to overcome technical challenges the specific research focus of our laboratory inspires you you love to gather information from the literatures and helps generate creative ideas and technical solutions you relish working on technically challenging problems, which often require an extended persistent effort to crack Job Description, Qualification, and Expectations: Primary activities in this position include, but are not limited to: Expression and purification of the protein complexes for biochemical and structural studies (cyo-EM, crystallization Structure determination of the protein complexes by cryo-EM or/and X-ray crystallography Biochemical assays to characterize the recombinant protein complexes Providing intellectual contributions to the projects including writing manuscripts, fellowship application and helping PI for grant applications Ph.D. in structural biology (X-ray crystallography, cryo-EM) is strongly preferred. If interested, please email a cover letter, CV, and two reference letters to ytakagi(a)iu.edu Applications will be screened until a suitable candidate is found. Indiana University is an equal opportunity/affirmative action employer.

Submitting SLURM jobs through PHENIX GUI
by Thomas Cleveland 01 Nov '18

01 Nov '18

Hi all, Has anyone gotten SLURM job submission to work through the PHENIX GUI? Under Preferences/Processes, I set Queueing system to SLURM with queue submit comand "sbatch." The job does indeed submit to the queue, and I can see it in the listing using the "squeue" command. However, there is quickly an error, "OSError : [Errno 2] No such file or directory: '/home/clevelandt/data/MX/181016_P1_merge/phenix/.phenix/tmp/10.libtbx_info.LOCK'". I've attached the full error log. Basically the program is looking for a lock file that isn't there. I'm not sure why it's not there. All compute nodes should have access to this directory, and there is no caching of any kind, so any files placed there should immediately be accessible. I can manually submit e.g. phenix.refine jobs to the queue using the command line and everything works fine. It would be really nice to have it through the GUI though. Thanks for any help, Tom

RNA starting with triphosphate
by Phoebe A. Rice 25 Oct '18

25 Oct '18

A question from my collaborators: what is the best way to get phenix to handle a GTP as nt #1 of an RNA chain? That is, what is the best way to specify a covalent bond with the proper geometry between the 3’ O of GTP1 and the 5’ P of nt #2? Thanks in advance, Phoebe ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Phoebe A.
