---------- Forwarded message ---------- From: Nukri Sanishvili <rsanishvili(a)anl.gov> To: <phenixbb(a)phenix-online.org> Date: Mon, 3 Feb 2014 18:12:09 -0600 Subject: CCP4 crystallographic summer school in USA, at APS, June 24-July 2 Dear Colleagues, We are pleased to announce the seventh annual CCP4 crystallographic summer school at Advanced Photon Source (APS), Argonne National Laboratory (ANL). All details can be found at http://www.ccp4.ac.uk/schools/APS-2014/index.php<https://mail.anl.gov/owa/redir.aspx?C=Qww5V7BVpECZd8A2kldFSf7_-DvC9NAIxdFZE…> *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<https://mail.anl.gov/owa/redir.aspx?C=Qww5V7BVpECZd8A2kldFSf7_-DvC9NAIxdFZE…> *Fees: *There is no fee for the workshop. The students will be responsible for their transportation and lodging. The workshop organizers can help make the reservations at economical lodging at the Argonne Guest House. The workshop will also cover the expenses for all meals and refreshments. We hope to see you at the school, Garib, Ronan and Nukri -- Ruslan Sanishvili (Nukri) Macromolecular Crystallographer GM/CA@APS X-ray Science Division, ANL 9700 S.

Re: [phenixbb] autosol error// phaser error

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
