Hi Sharan, I am getting the same error saying , 'is not a known sequence type'. Also, please see the image enclosed below that tells how the template sequence file should look like. I tried with/without space after '>' sign and getting the same error message. [image: image.png] Any suggestion from anyone would be appreciated.

model shifts after real space refinement
by Ashok Nayak 15 Dec '21

15 Dec '21

Hi, Is there a way to say keep_origin=False in phenix real space refinement. I used it in the command line version of v3958. It didn't take that. There is a model shift after the refinement which I think is because the program brings the map to the origin and hence the refined model as well. Thanks, Ashok -- Post-Doctoral Fellow Department of Biochemistry and Molecular Biology, Sidney Kimmel cancer Center Thomas Jefferson University 1020 Locust Street, JAH Philadelphia, PA, 19107 Phone: 804-661-4620

Ligand CIF file in real space refinement
by Fadini, Alisia 06 Dec '21

06 Dec '21

Hello, I am trying to use phenix.real_space_refine to improve the fit between my protein's ligand and the electron density. I include a CIF file that has worked well for reciprocal space refinement, made through JLigand. It seems to me that the CIF file is read properly, it does not produce errors and the restrains are stated correctly in the output .cif file that includes all protein + ligand atoms. However, the output pdb shows a distorted ligand, where specific bond angles and bond lengths have been modified past what should be allowed by the restrains. Any insights on how to improve/the causes of this effect would be very welcome! My command is : phenix.real_space_refine model.pdb map.ccp4 ligand.cif resolution=1.63 Thank you, Alisia

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.

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!
