opportunity for experienced crystallographer
by Mooers, Blaine H.M. (HSC) 30 Nov '21

30 Nov '21

Associate Director of the Laboratory of Biomolecular Structure and Function The Laboratory of Biomolecular Structure and Function (LBSF) at the University of Oklahoma Health Sciences Center (OUHSC) seeks an experienced crystallographer to run the daily operations of the LBSF. The position is at the Assistant Professor of Research level. The candidate will be responsible for working with PIs to advance their structural biology projects. These efforts will include routine technical operations, developing new protocols to overcome challenging problems, and training the staff of user labs in protein purification, crystallization, data collection, and structure determination. The ideal candidate for this position will have a PhD and ten years of experience in macromolecular crystallography. The candidate will not be expected to write grant applications. Pluses in a candidate's background include experience with membrane protein purification and LCP crystallization, experience with Cyro-EM, or experience with other structural biology methods like microED, SAXS, SANS, XAFS, NMR, or XFELS. The LBSF is part of a suite of core labs supported in part by the OUHSC Vice President of Research. The LBSF is also part of the Biomolecular Structure Core (BSC) for the Oklahoma Center of Biomedical Research Excellence in Structural Biology (OCSB), which is based on the main campus in Norman. The BSC has contributed to the awarding of 23 million dollars in grant funding and 33 publications in the past nine years. The OCSB has been the focal point of Oklahoma's structural biology community for nine years. The community includes 50 labs at three major research institutions. The BSC will be a vital part of a new Center for Therapeutic Science. The center will coordinate and foster the drug development pipeline with the BSC playing a central role in structure-based drug design. The LBSF will be working closely with Dr. Matt Hart (https://basicsciences.ouhsc.edu/bmb/Faculty/bio_details/hart-matthew-phd-1), Director of the newly established Center for High Throughput Screening. Most of the 12 major users of the LBSF have cancer-related projects. One project led to the 2021 publication of crystal structures of RET Kinase bound to two drug molecules recently approved by the FDA for the treatment of non-small cell lung cancer. Most of the major users are members of the Stephenson Cancer Center, a National Cancer Institute-designated cancer center. The compensation level for this full-time position includes a generous benefits package. The position is based in Oklahoma City -- an affordable place to raise a family. To apply, please submit a cover letter, CV and contact information (name and email) for three references to Blaine Mooers, Director of the Laboratory of Biomolecular Structure and Function at OUHSC, at blaine-mooers at http://ouhsc.edu. The position will remain open until filled. Application review will begin immediately. OUHSC is an equal opportunity employer and is committed to creating a diverse and inclusive environment for all employees.

iotbx.merging_statistics on Python 3: too memory consuming
by Martin Malý 29 Nov '21

29 Nov '21

Dear PHENIX & CCTBX developers and users, I tried to calculate merging statistics with CCTBX tools using Python 3. I realized that the memory requirements are much higher comparing with Python 2... I closed all programs firstly so I had just 1.6 GB RAM used of 7.6 GB total RAM. Then I ran these two lines of code in the cctbx.python shell: import iotbx.merging_statistics i_obs = iotbx.merging_statistics.select_data(file_name="XDS_ASCII.HKL", data_labels=None) Python 2.7: The RAM usage went to 4.8 GB and then I was able to calculate merging statistics. Python 3.7: The module import was successful. Then the RAM usage went to total 7.6 GB and then the process was killed by the operating system (CentOS 7). Please, do you have any suggestion how to use this module "more carefully" and save memory? Thank you!

Dear Colleagues: The University of Missouri has initiated a major faculty hiring campaign, called MizzouForward, which intends to hire 150 new faculty members over the next 5 years. Successful candidates must be research leaders with a passion for collaboration and a proven track record of active, external research funding, particularly from federal agencies like NIH. This initiative coincides with the recent grand opening of the NextGen Precision Health research building, which houses a newly upgraded imaging center with a Krios G4 and Aquilos Cryo-FIB. Other investments in structural biology include a share of ALS beamline 4.2.2 and a Bruker 800 MHz NMR with cryoprobe. For more information, please see: https://provost.missouri.edu/mizzou-forward/ -- Jack Tanner (tannerjj(a)missouri.edu<mailto:[email protected]>) and Lesa Beamer (BeamerL(a)missouri.edu<mailto:[email protected]>) Department of Biochemistry University of Missouri 117 Schweitzer Hall 503 S College Avenue Columbia, MO 65211

Thresholding for N/Q/H errors in phenix.refine?
by Nicholas Gao 15 Nov '21

15 Nov '21

Hi, For the correction of N/Q/H errors in phenix.refine: is this option binary (that is, can it only be turned on or off)? Or can it be adjusted to be on but its stringency adjusted to an arbitrary scale? https://phenix-online.org/documentation/reference/refinement.html#id19 <--suggests its binary, but asking here for thoroughness. Sincerely, Nicholas Gao

superpose mrc maps (and also mtz files)
by Georg Mlynek 15 Nov '21

15 Nov '21

Dear Scientific community, I got a few .mrc maps from collaborators. Is there a way in phenix to superpose models and corresponding mrc maps. Using superpose maps I get the error:" This file format CCP4 map is not supported as input for this field; only files of type 'Reflections' are allowed. Also the program Structure comparison does not recognize .mrc files. On top there are also a few mtz files I would like to superpose on the .mrc files. Many thanks, br Georg.
