Dear all, I am using the latest Phenix; Calculate Maps does not seem to have an option to for kickmaps as given in the https://www.phenix-online.org/documentation/reference/create_maps.html I have made a screenshot: http://imgur.com/a/upgqy Am I missing something obvious? Alternately, If anyone can share a script I would prefer it! many thanks Veronica

ensemble refinement crash.
by Rajendra Sharma 25 Nov '16

25 Nov '16

Dear all, I am running ensemble refinement using phenix-1.10. The calculations are running good until the Ensemble reducer where the jobs get killed in some cases automatically without giving output pdb. I am using default setting to run the jobs. pdb_stored_per_block is 50 totaling 500 towards the end. Is the crash happening because of memory? Will reducing the number of pdb per block help? Secondly, how can I restart the killed runs? thanks in advance.

Postdoctoral positions at the NIH in structural and mechanistic studies on integral membrane proteins
by Anirban Banerjee 19 Nov '16

19 Nov '16

Position Description: The research group of Dr. Anirban Banerjee at the National Institutes of Health (NIH) is seeking candidates for postdoctoral fellows . The broad interests of the lab are in membrane protein structure and function. We combine structural techniques such as macromolecular crystallography with biophysical and biochemical methods such as reconstitution based biochemistry, electrophysiology together with synthetic chemistry to investigate the structural bases of the mechanisms of a number of membrane proteins. The lab has state-of-the-art equipment and facilities. We have dedicated periodic access to the 22-ID beamline at the APS, for crystallographers at the NIH, as well as access to 23-ID and 24-ID beam lines at the APS. Our laboratory is part of the Cell Biology and Neurobiology Branch in the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). We also have an affiliation to the National Institute of Neurological Disorders and Stroke (NINDS). Qualifications: The candidates should hold a Ph. D. degree, be author of at least one first author publication and have a strong background in biochemistry or structural biology. Experience with basic molecular biology, protein expression, purification and biochemical characterization are required. Prior experience in membrane protein biochemistry or insect/mammalian expression systems will be added advantages. It is absolutely essential the candidate is motivated and prepared to put in the best efforts for fruition of the project goals. We are a small, friendly lab and ability to work as part of a cohesive group is important. To Apply: Interested candidates can send an e-mail to anirban.banerjee(a)nih.gov with a CV and a summary of previous research experience and future interests.

gtk glib error messages and too large fonts when starting phenix 1.11.1-2575
by Martin Moche 19 Nov '16

19 Nov '16

Dear colleagues, Today I install latest stable phenix 1.11.1-2575 without problems - output attached. When starting the phenix GUI, the fonts are too large and I get a lot of Gtk, GLib error messages - see below These error messages can be found online as well https://mail.gnome.org/archives/meld-list/2015-January/msg00007.html and are therefore likely not related to phenix. Perhaps somebody knows how to get rid of them and get smaller fonts into phenix GUI?

Sorry: Refinement of multiple models not implemented.
by Murpholino Peligro 17 Nov '16

I was looking at pdb 2d6b and I try to do a refinement with phenix. (First I generated the cif file with phenix.elbow for 202 ( https://www3.rcsb.org/ligand/202). Then I retry the refinement and I got the error "Sorry: Refinement of multiple models not implemented." How to proceed? Thanks MP

Failed to refine B factors of some residues and ligands
by Zhou, Tongqing (NIH/VRC) [E] 16 Nov '16

16 Nov '16

Dear All, I am refining a structure with diffraction to 2.2A resolution and 95 % overall completeness. Now the Rs are at 18% and 23%, respectively. But the program failed to refine B factors for several ligands, atoms had high B factors while showing positive Fo-Fc map around them. Occupancy was set to 1 and I also tried to reset B to mean B of the whole PDB. Any of you seeing this phenomenon? Thanks! Shown below is HEPES that has high B factor and positive density around it after refinement: [cid:[email protected]] Best regards, Tongqing Tongqing Zhou, Ph.D. Co-head and Staff Scientist Structural Biology Section Vaccine Research Center, NIAID/NIH Building 40, Room 4609B 40 Convent Drive, MSC3027 Bethesda, MD 20892 (301) 761-7068 (Tel) (301) 793-0794 (Cell) (301) 480-2658 (Fax) ****************************************************************************** The information in this e-mail and any of its attachments is confidential and may contain sensitive information.
