phenix.AmberPrep
by Liu, Jing-Yuan 02 Apr '16

02 Apr '16

Dear PHENIX Developers, I would like to perform phenix.refine using amber gradient. I installed AmberTools 15 and the newest version of Phenix by following the instruction found here http://www.phenix-online.org/documentation/reference/amber.html.<http://www.phenix-online.org/documentation/reference/amber.html> However, when I ran"phenix.AmberPrep", it complains "phenix.AmberPrep not found". In dead, I cannot find any binary named "phenix.AmberPrep". However, it looks to me that phenix is installed OK and so does AmberTools 15. I checked each step of my installation, I could not find anywhere is wrong. Can you please help me out? Thank you! Sincerely, Jing-Yuan

Tautomer/protomer plugin for Phenix
by Lance Westerhoff 02 Apr '16

02 Apr '16

Hello All- A paper from our group just came out in ActaD which I think fellow phenix users should find interesting. The paper details a new module we have available which uses our QM/MM-based Phenix plugin to correctly refine and determine tautomer/protomer, rotamer, flip state, and binding mode using X-ray data and refinement. The paper is available for free, Open Access on ActaD’s website: http://scripts.iucr.org/cgi-bin/paper?S2059798316002837 If you would like to give it a try, please let me know. The software is available for free for pure non-profit academic research and for a reasonable fee for commercial/industrial efforts. For more information, please visit our product site: http://www.quantumbioinc.com/products/phenix_divcon Or fill out one of our on-line license agreements to gain access: http://www.quantumbioinc.com/products/software_licensing Thank you for your time and have a good weekend! -Lance ____________________ Lance M.

Hi, I have tried using Autosol through the Phenix GUI and it starts to run and then crashes with the following error. I could use some help figuring out what I need to do to fix this?

Selenocysteine

Hello, How to add an unnatural amino acid (say OCS) at a position in the sequence and view it in PyMol, provided the protein structure (PDB file) is given? Is it correct to make changes in the PDB file itself, if Yes, then how should I do it? Thank you. -- Shilpa J Bioinformatics Dept., SASTRA University.

symmetry rejected as inconsistent by model_vs_data
by wtempel 30 Mar '16

Hello, phenix.model_vs_data_1.10.1-2155, along with printing to stderr: Sorry: Crystal symmetry mismatch between different files. prints these, and only these, lines to stdout: x251682_scaled3.mtz (36.692, 53.798, 108.063, 90, 84.258, 90) P 1 21 1 readySet.pdb (36.69, 53.8, 108.06, 90, 84.26, 90) P 1 21 1 Is this related to this code <http://cci.lbl.gov/cctbx_docs/cctbx/cctbx.crystal.html#cctbx.crystal.symmet…> ? Can I force phenix.model_vs_data to omit this isomorphism check and “run” with the reflection dimensions? Thank you. Wolfram

BSR2016: 12th International Conference on Biology and Synchrotron Radiation
by Thomas Eriksson 30 Mar '16

30 Mar '16

The 12th International Conference on Biology and Synchrotron Radiation will be hosted by the SLAC National Accelerator Laboratory - August 21-24, 2016. The objective of the conference is to bring together the community of biologists and scientists involved in the methodological developments on synchrotron and X-ray laser sources to discuss the novel possibilities of these sources and to promote their applications to challenging biological problems. The scientific program for the 2016 BSR covers applications of diffraction, spectroscopy and imaging methods applied to the structural and time-resolved studies of biological macromolecules, complexes and cellular and sub-cellular structures. There will be a $500 early registration fee ($350 for students). To take advantage of the early fees, registration must be complete by June 30th. Full information about the meeting, scientific program, registration and abstract submission forms can be found at the conference web site: https://conf-slac.stanford.edu/bsr-2016/content/biology-and-synchrotron-rad… Ana -- ------------------------------------------- Ana Gonzalez <ana(a)slac.stanford.edu> Staff Scientist Stanford Synchrotron Radiation Lightsource 2575 Sand Hill Road, MS 99 Menlo Park CA 94025 Phone: (650) 926 8682 Fax: (650) 926 3292 -------------------------------------------

iNEXT / X-rays (and more) notes
by Anastassis Perrakis 24 Mar '16

24 Mar '16

Dear all, I want to bring to everybody’s attention a few things about iNEXT Synchrotron Access proposals, as they seem to surface up often. - “BAG” proposals are possible, but only when under a common translational scientific theme; not simply based on lab proximity. - iNEXT funds complete projects, both beam time and travel; arguing that "we have beamtime, just give us travel money” will likely get your proposal rejected. - Please be clear to state that you have crystals and/or justify what the SAXS experiments are answering. Please keep in mind a specific difference from past schemes: you do not need to submit a separate proposal to the synchrotron site to get beam time! A successful iNEXT application will be received by the site(s) you apply for, and only safety data will be requested and a technical review will be done based on the existing application. We are looking forward receiving your applications for high-end synchrotron data collection, but also for : 1. Structural Audit (including crystallisation trials and SAXS: please advertise to your biochemistry colleagues!) 2. Macromolecular Interactions (Biophysics for quantitative characterising) 3. Cryo-EM sample optimisation (if you have negative stain images) 4. High-end NMR data collection 5. High-resolution EM (if you have good cryo conditions, and also for tomography and CLEM) … and more modalities to come soon! http://www.inext-eu.org/access/ <http://www.inext-eu.org/access/> On behalf of the iNEXT team, Tassos

.Trash_UID error message
by Michael Weyand 24 Mar '16

24 Mar '16

Dear experts, our Phenix installation suffers on a nasty error message concerning permission problems on /data/.Trash_UID (/data is our mount point of a NFS share) when deleting a certain job from the history. Of course, no user has write access to the top folder / mount point! And I know that is might be an OS problem with NFS mounted disks (well known for Ubuntu systems). But we have an openSuSE with KDE, not GNOME. I also checked the Phenix preferences for an option, but was not successful. Is there any way to get rid of this message or better to say not deleting to .Trash folder? Thanks in advance, Michael
