rosetta.run_tests crash
by wtempel 25 Oct '19

25 Oct '19

Hi, has anyone tried the combination of phenix-1.17 and rosetta-2019.40? Crashes in my hands, crash log attached. I may have modified the phenix installation by phenix.python -m pip install readline, in case it matters. Any suggestions appreciated. Many thanks in advance. Wolfram Tempel

Yeast microtubule model
by Sebastiano Pasqualato 24 Oct '19

24 Oct '19

Dear all, I’m addressing to people working in the microtubule field. Has someone created, or knows where I could find, a pdb file of the yeast microtubule, or a portion of it? I’m interested in studying the contacts between subunits within the lattice. I know one could generate that using yeast tubulin dimers, but I don’t know exactly how. If someone has already done that and is willing to share it, that would be extremely helpful. Thanks a lot in advance, ciao, S PS: sorry for the cross posting to members of both bulletin boards. -- Sebastiano Pasqualato, PhD Biochemistry and Structural Biology Unit Department of Experimental Oncology European Institute of Oncology IFOM-IEO Campus via Adamello, 16 20139 - Milano Italy tel +39 02 9437 5167 fax +39 02 9437 5990

Phenix-RSR model fit issue in CS-Map
by pramod kumar 23 Oct '19

23 Oct '19

Dear Experts, I have a map generated through cryosparc (ab initio-reconstr and homo-refine at 3.7A* FSC and sharpened in Scipion and separately in EMAN2). I have build the initial pdb through BALBES which has perfect validation parameters and nice fitting in the map (with the mtz output) but the co-ordinates are shifted from the true origin of CS-map. I used phenix-RSR to fit and refine, but validation results remained too far to accept the model as good solution and also a small region entered in wrong nearyby densities. So far following independent and downstream approaches I have taken:- In phenix; dock in map, map to model, rigid body refine followed by real space refine (with both .map and converted .mtz), using only chain A-map boxing and model generation through NCS. I have tried chimera fit for entire assembly and also only one chain in boxed map and full map but still the validation remained far from acceptable values and a small region in wrong neighboring density. Please help. -- Best regards, Promod

errors in rosetta.refine
by Bram mylemans 18 Oct '19

18 Oct '19

dear I am trying to run rosetta.refine but get an error. I am using the latest version of phenix (1.17-3644) and I have tried to versions of rosetta (3.10 release date 2 Oct 2018 and 3.11 release date 26 Sept 2019) If I run rosetta.run_tests with rosetta 3.10 I get the following error message: DEBUG dumping error message ERROR: Rosetta exited with status 139 stderr output: Segmentation fault (core dumped) If I run with rosetta 3.11 I get a different error message: DEBUG dumping error message ERROR: Rosetta exited with status 127 stderr output: /opt/rosetta_3.11_phenix/main/source/bin/rosetta_scripts.python.linuxgccrelease: error while loading shared libraries: libcifparse.so: cannot open shared object file: No such file or directory Are these version of rosetta and phenix compatible?

Small Molecule Discovery RFP - Deadline is October 28th
by Nick DeHaan 17 Oct '19

17 Oct '19

Hi PhenixBB, I thought this group might be interested in an academic research support program that helps identify new active compounds based on protein structure. The award provides investigators, postdocs, or grad students with approximately 72 small molecules predicted by machine learning to bind to their protein of interest. A few awards also provide in-kind support (with a value of up to $20k) for the assay work. Applications take ~30 minutes to complete, and >300 awards will be given out this cycle. Proposals are due by October 28th. You can find out more here: Website: www.atomwise.com/aims <http://bit.ly/31rz1B4> Infographic: http://www.atomwise.com/wp-content/uploads/2019/10/AIMS-Infographic-Stats_F… <http://bit.ly/31jRa3O> Flyer: http://www.atomwise.com/wp-content/uploads/2019/10/Atomwise-AIMS-Awards-Fly… <http://bit.ly/31nkVAI> Please feel free to reach out to me with any questions!

high B Factor after real space refinement against a cryoEM map
by Keda Zhou 17 Oct '19

17 Oct '19

Dear all, I am trying to do the real space refinement for my model against a 5.0 angstrom cryoEM map. All parameters look pretty good except the B factor. The mean of the B factor is close to 400. I am just wondering whether the low resolution makes the B factor this high. Does anyone have any idea or suggestion on the high B factor during real space refinement? Is it possible to reduce it? What is the actual meaning of this B factor? Thanks in advance. cody

file location changed
by Cygler, Miroslaw 14 Oct '19

14 Oct '19

Hi, In order to allow synchronization of files on my mac with the cloud server I had to move all files used by Phenix to a new directory, including the main Phenix folder. How do I change the paths to these files in phenix so that they are accessible to the software? Phenix would not start without the main Phenix folder returned back to the old location. How do I rectify this as well? Thanks for your help, Mirek
