Re: [phenixbb] Using PyMOL-1.8 with PHENIX-dev-2306

Hi Billy Thanks for your reply. I installed phenix from source (phenix-installer-dev-2306-source.tar.gz). And I used scientific linux 7.1 for my workstation. I noticed that SCONS is adopted in the installation of phenix, and phenix will download a modified version of python (python_2.7.8_cci). I think the problem can be solved by adding a flag "--enable-unicode=ucs4" in configuring Python-2.7.8_cci. I'd appreciate if you can tell me how to modify the SCONS script file. by A.C. 2016-02-12 16:52 GMT+08:00 Billy Poon <bkpoon(a)lbl.gov>: > Hi, > > Are you installing phenix from source or from a binary distribution?

Specify space group with phenix.map_to_structure_factors?
by Oliver Clarke 16 Feb '16

16 Feb '16

Hi, I frequently use phenix.map_to_structure_factors to generate mtz files from EM maps for use in Coot - it is by far the best tool I have found for this purpose. For convenience (so I can easily build and refine one protomer of a four-fold symmetric entity), I often convert these mtz files from the default P1 to P4 spacegroup using CCP4, and I wonder if it would be possible to include an option to specify the output spacegroup directly in map_to_structure_factors (or perhaps it is there and I have missed it?)? Even better would be if there were a way to check the symmetry and refine the orientation of the input volume such that the map is centered in the unit cell and the symmetry axis of the volume is appropriately aligned - often I have aligned the input volume to another reference volume in Chimera, and if the alignment is not perfect the symmetry axis of the volume might be slightly misaligned from what would become the fourfold axis of the output. Cheers, Oli.

Update: Check for radiation-induced reduction of a disulfide bond
by Ezequiel Noguera 16 Feb '16

16 Feb '16

Sorry, my previous email was incomplete. My structure has negative density in the center of some disulfides (the magnitude of this effect vary between different monomers in the ASU). I'd like to refine the structure in an "artificial reduced form", where cysteines involved in disulfides are treated in reduced form, but repulsions originating from neighboring sulfur atoms are turned-off, to monitor distances (I expect that SG atoms remain close to 2 A), guided only by data. Thank you, Ezequiel

ensemble refinement
by George Kontopidis 16 Feb '16

16 Feb '16

Does ensemble refinement run on Phenix version 1.10.1-2155 (for windows) If yes can it run from GUI or only using command line? George

Re: [phenixbb] Arg, Glu, etc. naming conventions
by Mark A Saper 15 Feb '16

15 Feb '16

Apparently a torsion angle of –180° is considered very different from 0° because of the NH1.NH2 names. And the phenix convention is now different from coot.

Arg, Glu, etc. naming conventions

Phenix 1.10.1 is flagging several of my Arg residues with bad dihedral angles. Phenix is much more strict about NH1, NH2 naming conventions then 6 months ago. Can these be fixed with PDB Tools? How?

Check for radiation-induced reduction of a disulfide bond
by Ezequiel Noguera 14 Feb '16

14 Feb '16

I'm working with one protein, crystallized in oxidized form, which exhibits negative density in the Fo-Fc map at the center of the disulfide bond. As a test of radiation-induced reduction during data collection, I'd like to do a trial refinement described in a previous work from literature, where SG sulfurs of involved cysteines were refined without van der Waals interactions to monitor distances of these atoms. How can I do this calculation in Phenix? Thanks in advance

Using PyMOL-1.8 with PHENIX-dev-2306
by acyang 12 Feb '16

12 Feb '16

Hi everyone I've installed pymol and phenix on my scientific linux7.1 workstation. I can launch pymol via the launching script($PYMOL_HOME/pymol) normally. But when I launched pymol in phenix GUI, I got some error as followed: ********************************************************************************************************************************* Traceback (most recent call last): File "/opt/PyMOL/modules/pymol/__init__.py", line 71, in <module> import pymol File "/opt/PyMOL/modules/pymol/__init__.py", line 521, in <module> import pymol._cmd ImportError: /opt/PyMOL/modules/pymol/_cmd.so: undefined symbol: PyUnicodeUCS4_SetDefaultEncoding ********************************************************************************************************************************* After STFW*, *I knew the problem is about unicode variant (UCS2, UCS4).

I'd appreciate if any reply on this. acyang

reattach jobs
by andre.stiel 12 Feb '16

12 Feb '16

Hi, how do I reattach a job to a project in the GUI. Say I took the GUI to prepare a commands file (.eff) and save it. Then I run the actual refine from the command line on another computer using the save commands file. After the job is done, how do I get the job back in the GUI. I do not find something to „load“ or „reattach“ a job. Thanks. André André C.
