Running Phaser with a already placed solution from a previous job
by vincent Chaptal 05 Oct '17

05 Oct '17

Dear everyone, this sounds trivial but I somehow can't make it work so I would appreciate any pointer. I have placed a component using phaser and would like to expand my search using this already placed component as partial solution. I open the full-featured interface of phaser in the GUI and select the box "Use partial solution from previous job" and select the job (nothing seems to happen there). I define my ensembles with ensemble_1 as "fixed partial solution" and ensemble_2 the one to search for. I then get the error message that "ense_1 from previous job is not specified on the current ensemble tab". Using the info button I see that "It is best to do this by modifying the configuration of the GUI from the previous Phaser run instead of starting from scratch, because the stored solutions do not contain the definitions of the search ensembles" but I don't understand what is asked for me to do here. When I restore the previous job, I can't see how I can start a new search from there. Any help would be greatly appreciated. Thanks Vincent I'm using phenix 1.12-2829. -- Vincent Chaptal, PhD Institut de Biologie et Chimie des Protéines Drug Resistance and Membrane Proteins Laboratory 7 passage du Vercors 69007 LYON FRANCE +33 4 37 65 29 01 http://www.ibcp.fr

map model correlations in real_space_refine
by Daniel Larsson 04 Oct '17

04 Oct '17

In version 1.12, what does the new map correlation numbers CC_mask, CC_volume and CC_peak in the log mean? How do they relate to the old "Map CC (whole unit cell)" and "Map CC (around atoms)" values (which in my opinion are more intuitive/descriptive and very useful numbers and I don't understand why they are no longer written to the log). Regards, Daniel

help with phenix.ligand_identification
by Edward A. Berry 28 Sep '17

28 Sep '17

I'm having some problems using ligand_identification. I would like to restrict the search to a specific density peak, even if it is not the highest unmodeled peak or the highest Fo-Fc peak in the map. I tried using options: search_center="67.5 18.3 11.8" or ligand_near_res=S2063, Will the search be restricted to that region, or if a particuar ligand doesn't fit that blob, will it search through the rest of the map? If it is restricted, in what radius? Is this radius affected by the "search_dist" or "local_search" parameters? and local_search = True is default? Is there a threshold level for density level, below which building a ligand in a blob will not be attempted? I've tried with both search_center= and ligand_near_res=, and something gets built far away from that site. But there were errors, so I may have something wrong: phenix.ligand_identification mtz_in=sqr2803or13_031.mtz input_labels="2FOFCWT PH2FOFCWT" \ model=sqr2803or13_031.pdb ligand_near_res=S2063 nproc=2 After preparing the ligand library, then: Running LigandFit process 1...

The run continues, but it does not test any more ligands after those first two but goes on to evaluate the results. With nproc = 1, only 1 ligand gets tested. In all cases the first ligand in the library (2PE.pdb) is evaluated as the best. It is placed in density, but density that has already been built out with (and looks more like) a string of water molecules. And this is far from the selected residue or coordinates specified. The directory that raised the error when attempting to be deleted does eventually get removed: after the run there is no TEMP_N in the parent directory. Any suggestions would be welcome.

Hi all - Is it possible to download and install the latest Phenix release to a node on a computing cluster (i.e. without a screen and therefore web browser)? I've tried pasting the latest download links into `curl` and `wget` commands but get zero-size files as a result. Thanks, Jared

Deadline reminder: XChem fragment screening at Diamond (and iNEXT) - SUNDAY 1st OCTOBER
by Frank von Delft 23 Sep '17

23 Sep '17

Dear Protein Crystallographers and Drug Discoverers A reminder that we are again inviting proposals for performing crystal-based fragment screening at Diamond's XChem facility at beamline I04-1, for the next allocation period (April 2018 to Sept 2018). *The deadline for proposals is NEXT SUNDAY 1st OCTOBER 5PM.* *Details of how to submit at this page <http://www.diamond.ac.uk/Beamlines/Mx/Fragment-Screening/Applying-for-Fragm…>. * Full details of the facility are available here <http://www.diamond.ac.uk/Beamlines/Mx/Fragment-Screening.html>. It supports the full crystal-to-structure experiment, and since opening for users in 2015, it has hosted over 50 users from academia and industry, with over 65 experiments (>50k crystals) consistently yielding credible, high quality fragment hits. With the right crystals, it'll keep you busy for less than a few weeks; and you get lots of support and advice. The calls are heavily oversubscribed, so please pay close attention to the instructions and guidelines. Access for EU users is funded via iNEXT <http://www.inext-eu.org/> (but only if you follow the instructions!); however we welcome all international proposals. -- Prof Frank von Delft Associate Professor Principal Beamline Scientist: I04-1 Diamond Light Source +44 1235 778997 Principal Investigator: Protein Crystallography Structural Genomics Consortium Oxford University +44 1865 617583 Visiting Professor Department of Biochemistry University of Johannesburg South Africa

Hi， I got an error message when I try to refine a molecular replacement result. It says "number of nonbonded interaction distances<0.001:10. Please inspect the out put above(or in the log window) and correct the input model file." Could you help me with this problem? The error happens when I add Mg to pdb file. Thanks!

Weird occupancy values in HySS
by Dominic Gilzer 21 Sep '17

21 Sep '17

Dear everybody, I am using Phenix HySS to solve the substructure of an iodine soak. I tried several high resolution cut-offs and a varying amount of heavy atoms to search for, but consistently get occupancies of > 1.0. Has anyone noticed such values for occupancies before, and by chance knows how or why these occur? Best regards, Dominic

Hi, I got an error message when I try to refine a molecular replacement result. It says Fatal problems interpreting model file: Number of atoms with unknown nonbonding energy type symbols: 18 Please edit the model file to resolve the problems and/or supply a CIF file with matching restraint definitions, along with apply-cif-modification and apply-cif-link parameter definitions if necessary. Could you help me with this problem? Thanks! Best regards, Jiemin
