Rosetta refinement fail on Mac
by Aaron Oakley 22 Aug '18

22 Aug '18

System: macOS 10.13.6 Phenix version: phenix-1.14rc1-3177 Rosetta version: 3.9 (rosetta_src_2018.09.60072_bundle) So I rebuilt rosetta 3.9 as root and can now run "Rosetta refinement". However...Rosetta refinement ran for 2 hours, slowly gobbling memory up to a maximum of 25GB before failing (error below). Also gobbled up disk space, creating a 78 GB file “outtmp.map”. A memory leak issue? Thanks, a++ RuntimeError : File 'None' not found. Traceback: File "/Applications/phenix-1.14rc1-3177/modules/cctbx_project/libtbx/runtime_utils.py", line 179, in run return_value = self.target() File "/Applications/phenix-1.14rc1-3177/modules/cctbx_project/libtbx/runtime_utils.py", line 74, in __call__ result = self.run() File "/Applications/phenix-1.14rc1-3177/modules/phenix/phenix/command_line/rosetta_refine.py", line 304, in run return run(args=list(self.args)) File "/Applications/phenix-1.14rc1-3177/modules/phenix/phenix/command_line/rosetta_refine.py", line 191, in run debug=params.output.debug) File "/Applications/phenix-1.14rc1-3177/modules/phenix/phenix/rosetta/refine.py", line 313, in __init__ self.run_jobs() File "/Applications/phenix-1.14rc1-3177/modules/phenix/phenix/rosetta/refine.py", line 388, in run_jobs check_result(result) File "/Applications/phenix-1.14rc1-3177/modules/phenix/phenix/rosetta/refine.py", line 383, in check_result raise RuntimeError("File '%s' not found." % result.file_name)

rosetta installation problem ubuntu 18.04

Dear Scientific Community, I am struggling installing rosetta on ubuntu 18.04.1 LTS and phenix 1.14-3211-000. I followed the instruction as in https://www.phenix-online.org/documentation/reference/rosetta_install.html the provided link https://c4c.uwc4c.com/express_license_technologies/rosetta gives an "This site can't be reached error" Therfore I went to https://www.rosettacommons.org/software and downloaded and unpacked in /home/g/programs/rosetta_src_2016.32.58837_bundle/ I added the line export PHENIX_ROSETTA_PATH=/home/g/programs/rosetta_src_2016.32.58837_bundle/ to .bashrc running rosetta.build_phenix_interface nproc=8 I can't remember if it was fine.

RSCC calculation for structures from ensemble refinement
by Ashraya Ravikumar 20 Aug '18

20 Aug '18

Hi, I performed ensemble refinement for an existing PDB structure using phenix.ensemble_refinement. May I know what is the best way to calculate real space correlation coefficient at the residue level for the ensemble? I tried using phenix.real_space_correlation but it gave me the following error: "Sorry: Multiple equally suitable arrays of observed xray data found." Thanks in advance. Regards, Ashraya Ravikumar, Graduate Student, Indian Institute of Science

Miao The glycans should be automatically linked and listed in the log file. You can do a quick check there. Cheers Nigel --- Nigel W.

Re: [phenixbb] Questions about refine glycans using PHENIX

Hi, yes, as long as the map shows the glycans clearly enough so that you can model them, then there is no problem refining your model using phenix.real_space_refine. Normally, there is no need to add anything special. Now I'm puzzled.. do you have a reason to believe that something isn't working correctly? By the way, we will be at Tsinghua University first week of September running Phenix workshop. We can discuss things while there!

Post Doctoral Research Fellow opportunity - Structural Chemistry Group at MD Anderson Cancer Center's Therapeutics Division.
by Leonard,Paul G 03 Aug '18

03 Aug '18

At MD Anderson, we have been working to eliminate cancer for more than seven decades and are ranked as one of the top two hospitals in cancer care every year since 1990. One of our greatest strengths is our ability to translate today's most promising laboratory findings into tomorrow's new, more effective and less traumatic treatments. We are recruiting exceptional national and international post-doctoral fellowsto join our Structural Chemistry group, part of the Institute for Applied Cancer Science. Applicants must be extremely motivated and possess a strong background in structural biology, including protein expression and purification, crystallization, and X-ray crystallography. Experience using other biophysical techniques would be an advantage. We are seeking only the most dedicated individuals who will join us in our quest to discover, develop, and deliver more effective treatments to our patients. This is a unique opportunity to participate in project-driven drug discovery research within a highly respected academic and clinical setting. We’re tackling cancer and neurodegeneration with a new plan — our Moon Shots Program - one that aims to improve prevention, early detection and treatment. Our research engines fuel innovation along the way. And innovation, collaboration and scale get us there faster. They give us the framework we need for success, and speed up development for new and more effective care. Our Missionis to integrate novel biological insights with drug discovery expertise to accelerate the development of innovative targeted therapeutics, both small molecules and biologics for unmet medical needs. Our work is conducted in an environment that brings together excellence in both academic and pharmaceutical discovery, as evidenced by recent publications.
