calculating anomalous differences from a model
by Jonathan Grimes 05 Apr '14

Given a refined protein structure, is there an straightforward way to calculate the anomalous differences as a function of resolution, at wavelength X. many thanks jon Dr. Jonathan M.

determining molprobity version?
by Pete Meyer 02 Apr '14

Hi, I may be missing something obvious, but how do I determine which version of molprobity is being used for generating the clash scores reported by phenix.model_vs_data ? Pete

error estimates on coordinates
by Benoît Masquida 28 Mar '14

28 Mar '14

Hello, Can someone shed light on the way coordinates errors are obtained in REMARK 3 using maximum of likelihood as compared to Luzzati or sigmaa? What article can be cited in this respect? Thanks in advance.

phenix.pdbtools model_statics=true
by Maehigashi, Tatsuya 27 Mar '14

27 Mar '14

Hi all, What would be the best way to define the "selection" to show average B factors using phenix.pdbtools from command line? I've tried several ways using something like... phenix.pdbtools XXXXX.pdb stop_for_unknown=false model_statistics=true selections="chain QA or chain RA" However, the output always contain the standard/default "ADP statistics" table only (not for the selection I specified). Yes, I'm aware of the GUI option (under other tools) and it works great. However, I'm trying to compute average b for 9 coordinates under 4 separate categories (protein, RNA, ligands... and such), and I think it'll be a lot easier from the command line (using some quick script, for example). Any input will be appreciated!

Obtaining just the Wilson B with Xtriage
by Morten Grøftehauge 27 Mar '14

27 Mar '14

Hi guys, Is there a way to just have phenix.xtriage compute and output the Wilson B factor and not do everything else? I want to run it on a lot of files and that would simplify things. Cheers Morten -- Morten K Grøftehauge, PhD Pohl Group Durham University

xtriage reindexing suggestions
by Todd Jason Green 25 Mar '14

25 Mar '14

Hello all- I am trying to merge a few partial Se datasets. I am certain that I will have to reindex one or more to make sure that + and - reflections are not jumbled up. Can someone confirm that xtriage take this into account in suggesting to reindex one dataset in relation to a reference dataset? ie. does it use something like maximizing the anomalous signal in suggesting whether or not reindexing is necessary? I think the below suggests as much but I wanted confirmation: Automatic re-indexing For each data set supplied (other than the first data set given), all possible re-indexing matrices are derived as described by Grosse-Kunstleve et al. (2005). Each data set isautomatically re-indexed using the matrix that maximizes the correlation of amplitudes Have a good weekend. -Todd My Example: Reference analyses The following reindexing operators have been found: ------------------------------------------------- | Operator | Correlation | matches (%) | choice | ------------------------------------------------- | -k,h,l | 0.874 | 70.1 | <--- | | h,k,l | 0.032 | 76.7 | | ------------------------------------------------- If the data is reindexed with operator (-k,h,l), the correlation of the intensities to the reference data is maximized. sx205b_anom.sca This can be done for instance with: phenix.reflection_file_converter sx205b_anom.sca --change_of_basis="-k,h,l" <output_options>

Multiprocessor refine
by Kenneth A. Satyshur 24 Mar '14

24 Mar '14

The FAQ on the web says that phenix.refine uses multiprocessors, yet only phenix.autobuild seems to use MP. Do I need a special version of Phenix? I am using GUI 1.8.4-1496 >How can I use multiple processors to run a job? >Only AutoBuild(http://www.phenix-online.org/documentation/autobuild_gui.htm), LigandFit(http://www.phenix-online.org/documentation/ligandfit_gui.htm), phaser.MRage(http://www.phenix-online.org/documentation/MRage.htm), phenix.refine(http://www.phenix-online.org/documentation/refine_gui.htm), the structure comparison GUI(http://www.phenix-online.org/documentation/structure_comparison.htm), and phenix.find_tls_groups support runtime >configuration of parallel processing. In most cases this is done by adding the "nproc" keyword, for instance: etc RHEL6 x86_64 thanks kas -- Kenneth A.

All details can be found at http://www.ccp4.ac.uk/schools/APS-2014/index.php *Title:*"CCP4 crystallographic school: From data collection to structure refinement and beyond" *Dates*: June 24 to July 2. *Site:* Advanced Photon Source, Argonne National Laboratory, Argonne, Illinois (Near Chicago), USA *The school content: *Data collection workshop the first two days: beamline training and data collection on GM/CA@APS beamlines 23ID-B and 23ID-D. For data collection, only the participants' crystals will be used. Software workshop: The rest of the time after data collection will feature many modern crystallographic software packages taught by authors and other experts. It will be organized in three sections - lectures, tutorials and hands-on trouble-shooting. There will be model data sets available for tutorials but data, provided by participants, will have higher priority for the hands-on sessions. *Applicants*: Graduate students, postdoctoral researchers and young scientists at the assistant professor level are encouraged to apply. Only 20 applicants will be selected for participation. Participants of the workshop are strongly encouraged to bring their own problem data sets or crystals so the problems can be addressed during data collection and/or computation workshops. *Application*: Application deadline is April 11. The application form, the program, contact info and other details can be found at http: http://www.ccp4.ac.uk/schools/APS-2014/index.php<http://www.ccp4.ac.uk/schools/APS-2013/index.php> *Fees: *There is no fee for the workshop.

MRage run
by Jobichen Chacko 17 Mar '14

17 Mar '14

Dear All, I am running a molecular replacement using MRage program for almost 1 week with 4 threads, but yet to finish the run. I am using Phenix Version dev-1549 I am having a pretty big protein (around 100 KDa). I gave data file, sequence file, one model pdb and output from HHpred as input. Is there anyway to to find out when it is going to finish the run, or I can extract any information from the current run, if I manually end the run? Thank you. Jobi
