by Renwick Dobson 14 May '19

14 May '19

Dear AUC and Structural biology community, AUC2019<https://auc2019.uleth.ca/>, the 24th AUC Workshop and Symposium, will be held at the University of Canterbury, Christchurch (New Zealand) from 24-29 August 2019. Registrations are now open and details can be found at this website: https://auc2019.uleth.ca/. Early Bird Registrations close on 15th June. As the scientific program<https://auc2019.uleth.ca/symposium.php> for AUC2019 emerges, events will be uploaded to the website. We strongly encourage you to submit abstracts for talks and posters<https://auc2019.uleth.ca/abstracts.php>. The format of the event is a 2-3 day workshop<https://auc2019.uleth.ca/workshops.php> offering parallel, hands-on training in experimental design and the latest AUC data analysis software from the world experts in this area followed by a 2 day research symposium on AUC and complementary approaches: methodological development, combination with orthogonal techniques (SAXS, SANS, SPR, MST, SEC-MALLS etc), application in biosciences and material sciences. The meeting is also timed such that delegates can also attend the Biomolecular interactions and Engineering Symposium<https://www.queenstownresearchweek.org/bio-interactions/>, which is part of the Queenstown Molecular Biology Conference (this is in Queenstown, NZ), although note that this is a separate conference. Lastly, The European Biophysics Journal has kindly agreed to run a special issue to celebrate the research presented at AUC2019. Therefore, we invite those who wish to extend their talks to a journal publication to consider contributing original research articles to this issue. Please indicate your interest for inclusion in this volume below. Deadline for registration of a contribution is August 30 2019.

MR-Rosetta installation
by Taberman, Helena 09 May '19

09 May '19

Dear Phenix bb, I am facing a problem when trying to instal Rosetta locally. I have installed Rosetta 3.9, set a local environment to my c-shell (setenv PHENIX_ROSETTA_PATH "/Applications/rosetta_src_3.10_bundle") and compiled with ./scons.py -j4 mode=release bin in main/source/ folder. When I try to run rosetta.run_test I get the following error:"OSError: [Errno 2] No such file or directory: '/Applications/rosetta_src_3.10_bundle/main/source/bin' " though the folder is there. Could you please help me?

Rosetta cannot Rebuild
by Perry, Kay H. 09 May '19

09 May '19

I am having a problem with mr_rosetta where I cannot make it past the rebuild step. I have made fragment files using the old Robetta Server and I am using a hhpred alignment file, but even if I try with a model_already_placed when I reach rebuilding, I get the following error. protocols.looprelax: === protocols.looprelax: === Remodel protocols.looprelax: === ERROR: frag_libs().size() > 0 ERROR:: Exit from: src/protocols/comparative_modeling/LoopRelaxMover.cc line: 47 7 My PHENIX_ROSETTA_PATH is pointed at /share/apps/necat/programs/rosetta3.4 so I believe I am using version 3.4 of rosetta.

Dear PHENIX developers, I would like to know if the refinement.geometry_restraints.edits.scale_restraints still a valid option for tightening local restraints. I didn’t see this option from the phenix —show-defaults=all. I saw this option on the FAQ webpage. thx Wei

Phaser Small Molecule MR
by Whitley, Matthew J 02 May '19

02 May '19

Hello all, We have collected electron diffraction data to approximately 1.8 Å on a 'small molecule' of roughly 1660 Da. The space group (P 43 21 2) and unit cell parameters determined during data reduction match the known, published values, and our data are roughly 80% complete in all resolution shells from 17 - 1.8 Å. We would like to solve this structure by molecular replacement in Phaser, but are having a bit of difficulty doing so. Our problems all seem to be related to specifying the composition of the target molecule for Phaser. Via the phenix GUI, we can only specify the target composition as either protein or nucleic acid, when in fact the target is neither. The chemical composition of the target is C72 H85 N19 O18 S5. Is there a way to feed this chemical composition to Phaser and to get it to understand that the target is neither protein nor nucleic acid? Furthermore, according to our reading of the Phaser documentation, specifying "protein" leads to an assumed solvent content of 50%, which is likely to be a substantial overestimation for this small molecule crystal. We have also run into the problem of Phaser complaining that the target molecule will not fit into the given unit cell, which we think is due to the assumption of 50% solvent content. We would be thankful for whatever advice you may have on using Phaser with non-protein, non-nucleic acid molecules. Matthew --- Matthew J. Whitley, Ph.D. Research Instructor W.
