phenix.autosol and phenix.hyss now optimized for weak SAD data
by Terwilliger, Thomas C 06 Feb '14

06 Feb '14

Hi Phenix users! You might notice some big differences in HySS and AutoSol in the new 2014 versions of Phenix (starting with current nightly builds and the soon-to-be-released Phenix-1.8.5). The big changes are parallelization, the use of Phaser completion in HySS, iterative Phaser completion using maps and models in AutoSol, and on-the-fly optimization of parameters in AutoSol for cases with weak anomalous signal. Now HySS and AutoSol can solve structures with very weak SAD phase information that previous versions could not solve. More details will be in the Phenix newsletter that will come out shortly! You can see documentation on the new HySS at: http://phenix-online.org/version_docs/dev-1613/hyss.htm#anch8 and on the new AutoSol at: http://phenix-online.org/version_docs/dev-1613/autosol.htm#anch118 --Tom Terwilliger, Randy Read, Gábor Bunkóczi, Nat Echols

Re: [phenixbb] autosol error// phaser error
by Terwilliger, Thomas C 03 Feb '14

03 Feb '14

Hi Almudena, Can you possibly say what version of Phenix you are using: phenix.version and then the columns in your mtz file: phenix.mtz.dump my_mtz_that_fails.mtz and the inputs you used for autosol and phaser (you can send the top part of the log files that should have this information). Can you also try this little test for resolve model building (that is where the "cannot read segment library" comes from): phenix_regression.wizards.test_command_line_build test_autobuild_quick That would help for diagnosing the problems. All the best, Tom T Hi everyone, I am facing some troubles with PHASER and with AutoSol (things that did not happen earlier to me). I am working with anomalous data and the first thing I do is to run HySS in order to find the heavy atoms sites. Once this is done I have two options: run PHASER or run AutoSol. Phaser gives the following error message: ERROR setting up data inputs (FATAL RUNTIME) Can not find MTZ column "F_SAD_SAD(+)" Instead Autosol gives the following: ERROR sorry can not read segment library Could anyone help me out here? Thank you very much in advance. Best, Almudena -- Almudena Ponce-Salvatierra Macromolecular crystallography and Nucleic acid chemistry Max Planck Institute for Biophysical Chemistry Am Fassberg 11 37077 Göttingen Germany

by Wulf Blankenfeldt 27 Jan '14

27 Jan '14

Postdoctoral Position in Macromolecular Crystallography The Helmholtz Centre for Infection Research (HZI) in Braunschweig (Germany) announces an opening for a postdoctoral researcher in macromolecular crystallography. The position is associated with the department “Structure and Function of Proteins” headed by Prof. Wulf Blankenfeldt. The department focuses on unraveling molecular mechanisms of uncharacterized processes in the metabolism, regulation and virulence of pathogenic microorganisms. About the institute More than 800 people work at the HZI, a research institution in the Helmholtz Association of German Research Centres funded jointly by the Federal Republic of Germany and the Federal State of Lower Saxony. The centre’s task is to undertake biomedical research in the field of infection biology to expand knowledge of the fundamental mechanisms behind medically relevant infectious diseases with the aim of providing the key for the development of new therapeutics and vaccines. The Department “Structure and Function of Proteins” offers excellent working conditions, state-of-the-art technical platforms and equipment (including bacterial, insect cell and mammalian protein expression systems; access to a rotating anode X-ray source and several synchrotrons, crystal imaging and liquid handling systems; biophysical characterization of proteins), a lively scientific community and excellent support for the development of personal soft-skills. Projects All projects in our department aim at the identification and elucidation of the molecular function and mechanism of uncharacterized genes in pathogenic microorganisms. A better understanding of these “white spaces” of the genome map will not only unravel interesting new molecular processes but also provide novel targets for pharmaceutical intervention. To achieve our goal, we employ a gamut of methods including – in addition to structural biology – microbiological, biophysical and metabolomic techniques. Because our department is also the prime partner for structural biology-related questions at the HZI, the Technical University of Braunschweig and the German Centre for Infection Research (http://www.dzif.de/en/) the successful candidate will have the opportunity (and is expected) to take leading roles within our existing and emerging collaborations.

Re: [phenixbb] measuring the angle between two DNA duplexes
by Xiang-Jun Lu 26 Jan '14

26 Jan '14

Hi Xiang, Since you mentioned "or in other software", I think I can chime in to this topic. The short answer is to see "How to calculate DNA bending angle?" ( http://forum.x3dna.org/faqs/how-to-calculate-dna-bending-angle/). 3DNA, following the original NewHelix algorithm, calculates a best-fitted linear global helix (where sensible) using equivalent C1'...C1', RN9/YN1...RN9/YN1 atom pairs along each strand. The so-called global helical axis parameters are no longer widely used, but the best-fitted linear helical axis is a useful concept, and has been kept in 3DNA and DSSR [ http://forum.x3dna.org/rna-structures/dssr-software-for-defining-the-(secon… ].

non-bonded
by Leonard Thomas 23 Jan '14

23 Jan '14

Hello All, We are trying to refine a complex that was solved using Phaser. We have run a round of rigid body refinement using Refmac and now want to run a simulated annealing run in Phenix. Visually the complex looks pretty. The resolution we currently are at is 3.6 A. When we go to run phenix.refine the program quits with a Number of non-bonded interactions < 0.0001 error. Is there a way to loosen this up a bit or get around it or should we go about this in a different way?
