Post-doctoral position available with Phaser team
by Randy J. Read 24 Sep '08

24 Sep '08

We are looking to expand the team developing our program Phaser, for use within both the CCP4 and Phenix packages. Our goals include expanding the functionality to new phasing experiments (in addition to the options for molecular replacement and SAD that exist in the current version), and enhancing the automation of Phaser runs. The ideal applicant would be someone with experience solving macromolecular crystal structures and programming in both C++ and Python. However, if you only have experience in one of those areas, but a strong desire to expand your skills, then you might be the right person. If you're interested, please look at the formal advertisement (http://www.admin.cam.ac.uk/offices/hr/jobs/vacancies.cgi?job=4017), and submit an application as described there. I'm also happy to answer any informal enquiries. The position is funded by a grant from the Wellcome Trust, which extends to May 2013. Please note that the closing date for applications is 2 October 2008. Regards, Randy Read

chainid and segid?
by deborah.palestrant＠novartis.com 23 Sep '08

23 Sep '08

Hi Phenix Community- A very basic question.. Is there an option to have a "segid" automatically generated? (For example, in CNS generate.inp, it was possible to "convert chainid to segid if chainid is non-blank"). Unless I strip out the segid completely, I am running into problems when I add residues using Coot (which adds chainid, but not segid) and then follow up with refinement in Phenix.

phenix 1.3-rc4 vs. phenix 1.3-final
by Jianghai Zhu 19 Sep '08

19 Sep '08

Hi, I have done a couple of refinements using either phenix.refine 1.3-rc4 or phenix.refine 1.3-final. And phenix.refine 1.3-rc4 always gave me a lower Rfree, about 1% lower than phenix.refine 1.3-final, which actually is pretty big. What has changed between this two versions? -- Jianghai

phenix autobuild question
by Alex Berndt 16 Sep '08

16 Sep '08

Dear phenix community, I started an AutoBuild run using the phenix GUI (ver 1.3 rc4) on a linux cluster. It worked okay and all the refinement looked pretty decent. However, after quite a while I obtained the following error message (see below). Would anyone please tell me what to do to prevent this error and get phenix get its job finished? Also, I don't understand why phenix AutoBuild creates 5 (or whatever number) AutoBuild_run_x in the AutoBuild-run_1/TEMP0 directory and not two dirs up in the tree. In other words in my /someplace/home/someuser/ work/someproject/phenix2/AutoBuild_run_1_/TEMP0 directory are more AutoBuild_run_x_ directories (with x=1 to 5). It is a bit confusing to me. A final question: I realised that the phenix.refine drastically increases the number of outliers. I know that thare is a weighting term someplace ... but what was it again? Many thanks in advance, Alex warnings Failed to carry out AutoBuild_multiple_models: Sorry, subprocess failed...message is: ******************************************************************************** phenix.autobuild \ write_run_directory_to_file=/someplace/home/someuser/work/someproject/ phenix2/AutoBuild_run_1_/TEMP0/INFO_FILE_1 Reading effective parameters from /someplace/home/someuser/work/ someproject/phenix2/AutoBuild_run_1_/TEMP0/PARAMS_1.eff Sending output to AutoBuild_run_1_/AutoBuild_run_1_1.log ******************************************************************************** Failed to carry out AutoBuild_build_cycle: failure ******************************************************************************** ******************************************************************************** work_pdb_file "AutoBuild_run_1_/edited_pdb.pdb" working_directory "/someplace/home/someuser/work/someproject/phenix2" worst_percent_res_rebuild 2.0 --------------------------------------------------- Alex Berndt MRC-Laboratory of Molecular Biology Hills Road Cambridge, CB2 0QH U.K. phone: +44 (0)1223 402113 ---------------------------------------------------
