temp files
by James Holton 26 Apr '21

26 Apr '21

Hello all, Is there a way to configure phenix at install time (or perhaps post-install) to put temporary files under /tmp ? I just had to delete 20e6 temp files over NFS from a single user's phenix ligand identification run. The delete took almost a month. Apologies if I am neglecting to look somewhere obvious in the documentation, Happy Weekend! -James Holton MAD Scientist

Caltech Postdoc Position
by Hoelz, Andre 19 Apr '21

19 Apr '21

The Hoelz laboratory at the California Institute of Technology seeks to recruit two outstanding postdoctoral scientists in structural cell biology. Our laboratory focuses on the structure-function relationships of the nuclear pore complex and associated nucleocytoplasmic transport machinery. This position requires a recent Ph.D. degree in biochemistry/biophysics with a strong background in biochemistry, x-ray crystallography, and/or cryo-electron microscopy/tomography. The successful applicant should be a highly motivated individual with good organizational, communication, and interpersonal skills, who is able to carry out a structure determination project from the development of recombinant protein expression systems to structure refinement. The laboratory is well-funded and equipped with modern biophysical instrumentation. Importantly, Caltech has an exceptional infrastructure for structural biology, including access to a high intensity, completely automated, state-of-the-art crystallography beamline at the Stanford Synchrotron Radiation Lightsource (SSRL), as well as an excellent cryo-electron microscopy facility with access to FEI Arctica and Titan Krios microscopes equipped with Gatan K3 cameras. The positions are available immediately and funded for 3+ years. Depending on performance, the position can be extended for additional years. To apply, please send your CV, a statement of research interests, and the names and contact information of at least two references to André Hoelz (hoelz(a)caltech.edu<mailto:[email protected]>).

Hi everyone. I've installed open source pymol, coot, and phenix on my Windows 10 laptop. Pymol, python, and coot works fine, but when I launched phenix, it didn't work I tried both 1.18 and 1.19 version point-and-click installers. So I executed phenix on cmd, and the following error occured: ****************************************************************************** C:\Program Files\Phenix\phenix-installer-1.18.2-3874-intel-windows-x86_64\build\bin>phenix Traceback (most recent call last): File "C:\Program Files\Phenix\phenix-installer-1.18.2-3874-intel-windows-x86_64\build\..\modules\phenix\wxgui2\command_line\main.py", line 23, in <module> run(sys.argv[1:]) File "C:\Program Files\Phenix\phenix-installer-1.18.2-3874-intel-windows-x86_64\build\..\modules\phenix\wxgui2\command_line\main.py", line 17, in run wxapp = App.PhenixApp(args) File "C:\Program Files\Phenix\phenix-installer-1.18.2-3874-intel-windows-x86_64\modules\phenix\wxGUI2\App.py", line 70, in __init__ wx.App.__init__(self, 0) File "C:\Program Files\Phenix\phenix-installer-1.18.2-3874-intel-windows-x86_64\conda_base\lib\site-packages\wx-3.0-msw\wx\_core.py", line 8628, in __init__ self._BootstrapApp() File "C:\Program Files\Phenix\phenix-installer-1.18.2-3874-intel-windows-x86_64\conda_base\lib\site-packages\wx-3.0-msw\wx\_core.py", line 8196, in _BootstrapApp return _core_.PyApp__BootstrapApp(*args, **kwargs) File "C:\Program Files\Phenix\phenix-installer-1.18.2-3874-intel-windows-x86_64\modules\phenix\wxGUI2\App.py", line 90, in OnInit self.setup_user_dir() File "C:\Program Files\Phenix\phenix-installer-1.18.2-3874-intel-windows-x86_64\modules\phenix\wxGUI2\App.py", line 364, in setup_user_dir os.environ['PHENIX_DATA'] = wxGUI2.PHENIX_USER_DIR File "C:\Program Files\Phenix\phenix-installer-1.18.2-3874-intel-windows-x86_64\conda_base\lib\os.py", line 422, in __setitem__ putenv(key, item) *UnicodeEncodeError: 'ascii' codec can't encode characters in position 9-11: ordinal not in range(128)* ****************************************************************************** I found out that unicode errors occur frequently and are easy to fix, but I can't figure out which file and which line I should manipulate.

phenix.ligand_identification search_center
by Tanner, John J. 31 Mar '21

31 Mar '21

Phenix BB: I would like to use phenix.ligand_identification to analyze an electron density feature in the active site of an enzyme; however, I do not see how to specify search_center in the gui. Thus, the program places the ligands into a strong density feature on the surface of the protein. When I run it from the command line with search_center specified, it seems to ignore the search center coordinates and again places the ligands into the density feature on the surface. My command script: [tannerjj@europa ligandID]$ cat ligandID.com phenix.ligand_identification \ mtz_in = "/titan/tanner/MmP5CDH/THLP/MmALDH4A1_THLP8-1_003.mtz" \ mtz_type = diffmap \ input_labels = "FOFCWT PHFOFCWT" \ ligand_list = "DPR PRO HYP HZP UYA UY7" \ model = "/titan/tanner/MmP5CDH/THLP/MmALDH4A1_THLP8-1_003.pdb" \ ncpu = 4 \ output_dir = "/titan/tanner/MmP5CDH/THLP/ligandID/temp" \ number_of_ligands = 6 \ job_title = "THLP8-1_003 D,L-Pro and 4 OH-Pro stereoisomers" \ search_center = "-12.597 11.990 21.741" [tannerjj@europa ligandID]$ Thanks, Jack -- John J.
