Anisotropy with TLS
by Eugene Osipov 31 May '18

31 May '18

Hi, everyone, Can someone shed a light on B-factor refinement in PHENIX.refine. I am refining the structure with 2.5 A resolution, with individual B-factors and automatically defined TLS groups. Despite isotropic refinement of B-factors I still see ANISOU entries for atoms. I figured out that these ANISOU lines appear only after TLS refinement. So the question is how these ANISOU values are calculated? -- Eugene Osipov Junior Research Scientist Laboratory of Enzyme Engineering A.N.

d99 resolution measure availability?
by Oliver Clarke 27 May '18

27 May '18

Hi, I think the “d99” criterion described in this preprint (https://www.biorxiv.org/content/early/2018/03/14/279844) looks like a really interesting FSC-independent way to measure res in real space, and I’d like to give it a go on my maps (particularly those where I am suspicious of the FSC-based res based on map appearance, or where I suspect overfitting). Is it available in any phenix package at present? The scripts site mentioned in the preprint (http://phenix-online.org/phenix_data/afonine/cryoem_validation/) is currently rather sparsely populated. (Also, I wonder whether a directional version of the d99 criterion might be useful to estimate anisotropic res in the case of a preferred orientation, analogous to the 3D-FSC approach of Yong-Zi Tan and Dmitry Lyumkis?) Cheers Oli

Phenix.rosetta build Ubuntu 16.04

08 May '18

Dear phenix community, I am trying to get phenix to run with rosetta on my Ubuntu 16.04 station. I am running the latest official phenix version (phenix-1.13-2998) and and compiled rosetta 3.7 (2016.32.58837) using scons as described: https://www.phenix-online.org/documentation/reference/rosetta_install.html https://www.rosettacommons.org/docs/latest/build_documentation/Build-Docume… Then ran rosetta.build_phenix_interface. All went without error but running rosetta.run_tests then gave the segmentation fault below. Defining variables as suggested did not help. I found a similar question in the phenixbb archives but no resolution: http://www.phenix-online.org/pipermail/phenixbb/2013-October/020274.html Any suggestions on how to move forward greatly appreciated!

Introducing ISOLDE
by Tristan Croll 01 May '18

01 May '18

Dear members of the structural biology community, It is with great pleasure that I announce the release of version 1.0b1 of ISOLDE, a new, free for academic/nonprofit use, environment for interactive rebuilding of macromolecular models against low-medium resolution experimental crystallographic or cryo-EM maps. A paper describing ISOLDE is online at http://scripts.iucr.org/cgi-bin/paper?S2059798318002425, and you can also get an overview from my demonstration video at https://www.youtube.com/watch?v=limaUsNAVL8. In brief, though, ISOLDE is designed to help overcome the substantial challenge involved in building high-quality models into “difficult” maps (e.g. those with worse than 3Å resolution) by re imagining the task as one akin to interacting with a real, “living” molecule. At its heart is the use of interactive molecular dynamics: all atoms feel van der Waals and electrostatic interactions with their neighbours as you interact with them, avoiding clashes and constantly settling towards their nearest low-energy state. In addition to this, ISOLDE helps interpret what you're looking at by performing real-time rotamer, Ramachandran and peptide plane validation, flagging up potential problems directly on the model to give you instant feedback on the results of your actions. Specific features: - support for protein, nucleic acid, water and some small molecules/ions (with substantially expanded support to come in later versions) - start an interactive simulation covering anything from a few residues to your entire model (depending on your hardware) at the click of a button - “always-on” validation updates every time coordinates change (results are shown directly as markup on the model itself, and also accessible via more traditional tables/plots) - Interactively apply peptide plane or cis/trans flips and add/remove position, distance, rotamer and secondary structure restraints via a simple graphical interface - Smoothly shift any continuous stretch of backbone forward/backward along the chain to easily recover from register shift errors - Save a checkpoint in a running simulation and return to it with a button click, allowing you to experiment with tricky regions without fear - Real-time visualisation of crystal symmetry contacts: when the master atoms move, they move. - One-button masking of maps to cover any arbitrary atom selection – particularly useful for diagnosing large-scale problems. - Extensive GUI and API documentation, available by clicking the “Help” button in the ISOLDE GUI window. ISOLDE is built as a plugin to UCSF ChimeraX (http://preview.cgl.ucsf.edu/chimerax/download.html) and is currently available for modern Linux distros and MacOS, and can be installed from within ChimeraX via its ToolShed (Tools/More Tools...). It should run on any Linux version that supports ChimeraX itself. NOTE: due to some recent changes in the ChimeraX API, the current build will only work with the ChimeraX 0.6 release (not the version 0.7 daily builds). In terms of hardware, ISOLDE is designed based on the understanding that not everybody has access to high-performance computing facilities, so its minimum requirements are as modest as possible. The most important requirement is a GPU capable of OpenCL 1.2 or CUDA processing. My “go-to” machine for performance testing is a 2016-model gaming laptop equipped with a Nvidia GTX 1070 GPU – this achieves ~20 coordinate updates and >30 graphics updates per second with live validation on the included 229-residue demo model, indistinguishable from (or slightly faster than) my Xeon workstation. At the other end of the scale, it runs at usable speeds on my MacBook Air for simulations of a few dozen residues, sufficient for many tasks. I hope you find it useful, and enjoy using it as much as I've enjoyed making it. The MolProbity score to beat on the demo model is 1.02 (after refinement in your favourite package – ID is in the PDB header so you can download reflections from the wwPDB), and bonus points if you can identify the mystery ligand (I can't). If you recognise it as your model I apologise – I picked it out at random, I swear! Best regards, Tristan

Abstract deadline is TOMORROW for Diffraction Methods in Structural Biology GRS
by Pearce, N.M. (Nick) 27 Apr '18

27 Apr '18

Dear BB, Tomorrow is the abstract deadline for the Gordon Research Seminar in Diffraction Methods 2018 at Bates College, Maine (28-29th July 2018). Applications/abstracts received after this date (28th April) will still be able to attend and present posters, but will not be considered for oral presentations. This year’s title is Crystallography 2.0: Restructuring the Field Around a New Wave of Experiments We want to have as many young scientists (Post-docs, PhD candidates & Master’s students) at the GRS (and associated GRC) as possible. For Jessica and myself, the 2016 Diffraction Methods GRS & GRC was the best conference we’ve attended during our PhDs, since it allowed us to present our research directly to our peers in a relaxed setting; it also gave many of us the opportunity to gain first-hand experience as session chairs -- an opportunity that is difficult to find as a young scientist. On top of this, the intimate nature and relatively small size of Gordon conferences helped us to build more long-lasting international connections than at any other conference we have attended. Of course, the GRS can only be truly successful if a wide variety of viewpoints are represented — so please consider attending. We would greatly appreciate it if you could also forward this invitation to any young scientists for whom you think this conference might be valuable. You can apply for the seminar (GRS) here: https://www.grc.org/diffraction-methods-in-structural-biology-grs-conferenc…. On this page you can also find a link to the associated Gordon Research Conference (GRC).

BCA/CCP4 Summer School in Protein Crystallography at Diamond
by Airlie McCoy 23 Apr '18

23 Apr '18

Applications are now open for the BCA/CCP4 Summer School in Protein Crystallography to be held at Diamond (UK) from Monday 27th August to Saturday 1st September 2018. Note that applications close 18TH MAY 2018 The BCA/CCP4 Protein Crystallography Summer School is intended for students and researchers new to crystallography. Its dual aims are to provide comprehensive training in crystallography and to promote best practise within the British crystallographic community. The lectures cover the gamut of techniques required for a structure solution, from protein expression through to structure validation. Intensively supervised computer tutorials enable students to relate the theory presented in the lectures to practice. Although CCP4 programs will primarily be used in these tutorials, the aim will be to approach crystallographic questions in a software-agnostic manner. There will also be a crystal manipulation and cooling workshop. Note that the course is scheduled during Diamond synchrotron downtime, so there will not be active data collection at the Diamond beamlines. Up to 10 places for those with BBSRC studentships will be fully funded. We recognise that the social programme plays a role in enabling students to make links that may be maintained throughout a research career. There will be a conference dinner, and a number of other events, including a trip to Oxford. For more information see http://www.diamond.ac.uk/Home/Events/2018/BCA-Summer-School.html Application form: https://extranet2.diamond.ac.uk/ISV/BCA/ApplicationForm.aspx

Protein structures sought for CASP13
by Paul Adams 20 Apr '18

20 Apr '18

Posted on behalf of the CASP organizing Committee: Critical Assessment of Techniques for Protein Structure Prediction (CASP) community experiments aim to advance the state of the art in protein structure modeling. Every other year since 1994, CASP collects information on soon-to-be released experimental structures, passes on sequence data to the structure modeling community, and collects blind predictions of structure for assessment. About 100 modeling groups from around the world participate. Results of CASP experiments are published in special issues of the journal PROTEINS (e.g., CASP12: https://onlinelibrary.wiley.com/toc/10970134/86/S1). The success of CASP depends on the generosity of the structure determination community. We are now requesting targets for CASP13 experiment, which will launch at the beginning of May. The CASP community needs modeling targets over a wide range of difficulty, for modeling with and without the aid of templates. X-ray, NMR and cryo-EM structures are welcome. We are particularly interested in membrane proteins, protein complexes, and cryo-EM structures. We are also extending CASP to include more modeling assisted by sparse experimental data, in collaboration with experimental groups in NMR, SAXS, SANS, crosslinking, and FRET. For that, protein material is needed (of course this is not expected for most targets, but if available, it would be much appreciated!). So, if you have anything suitable, we encourage you to mark your PDB deposition as a "CASP target" in the PDB's submission system. Alternatively, you can suggest your protein to CASP directly through the CASP13 target entry page: http://www.predictioncenter.org/casp13/targets_submission.cgi. For those of you who have not provided targets to CASP before, the procedure is simple and fast. We don’t need the structure in advance of its release by the PDB, and if we are notified early enough (a minimum of three weeks before release, more is better) there need be no delay in structure release. More details are available on the web site. CASP target providers are regularly invited to contribute to special issue papers, for example: 2018: Kryshtafovych A, Albrecht R, Baslé A, Bule P, Caputo AT, Carvalho AL, Chao KL, Diskin R, Fidelis K, Fontes CMGA, Fredslund F, Gilbert HJ, Goulding CW, Hartmann MD, Hayes CS, Herzberg O, Hill JC, Joachimiak A, Kohring GW, Koning RI, Lo Leggio L, Mangiagalli M, Michalska K, Moult J, Najmudin S, Nardini M, Nardone V, Ndeh D, Nguyen TH, Pintacuda G, Postel S, van Raaij MJ, Roversi P, Shimon A, Singh AK, Sundberg EJ, Tars K, Zitzmann N, Schwede T.

Call for not-yet-released structures as candidates for protein structure predictors
by Susan Tsutakawa 17 Apr '18

17 Apr '18

Critical Assessment of Techniques for Protein Structure Prediction (CASP) community experiments aim to advance the state of the art in protein structure modeling. Every other year since 1994, CASP collects information on soon-to-be released experimental structures, passes on sequence data to the structure modeling community, and collects blind predictions of structure for assessment. About 100 modeling groups from around the world participate. Results of CASP experiments are published in special issues of the journal PROTEINS (e.g., CASP12: Proteins Vol 86, Issue S1, March 2018). The thirteenth CASP round is scheduled to start on May 1, 2018. The organizing committee is particularly keen to include many cryo-EM-derived structure targets in this round. The success of CASP depends on the generosity of the structure determination community. Modeling targets are needed over a wide range of difficulty, for modeling both with and without the aid of templates. Targets that can be modeled based on structural templates should ideally have 50% or less sequence identity to the templates. Access to the structure in advance of its release by the PDB or its publication is not needed. With sufficient notification to CASP (a minimum of three weeks before release, more is better) there is no need to delay structure release. If you have recently determined a novel protein structure and will be depositing it to PDB, please suggest it as a target for CASP by visiting www.predictioncenter.org/casp13/targets_submission.cgi. If you have any questions please contact [log in to unmask] CASP target providers are regularly invited to contribute to special issue papers, for example: 2018: Kryshtafovych A, Albrecht R, Baslé A, Bule P, Caputo AT, Carvalho AL, Chao KL, Diskin R, Fidelis K, Fontes CMGA, Fredslund F, Gilbert HJ, Goulding CW, Hartmann MD, Hayes CS, Herzberg O, Hill JC, Joachimiak A, Kohring GW, Koning RI, Lo Leggio L, Mangiagalli M, Michalska K, Moult J, Najmudin S, Nardini M, Nardone V, Ndeh D, Nguyen TH, Pintacuda G, Postel S, van Raaij MJ, Roversi P, Shimon A, Singh AK, Sundberg EJ, Tars K, Zitzmann N, Schwede T.

R-factor expectations when translational pseudo symmetry is present
by Tanner, John J. 17 Apr '18

17 Apr '18

Dear PhenixBB, We have a crystal form that xtriage flags as having strong translational pseudo symmetry (Patterson peak 57% the height of the origin peak, p-value = 3E-5). The space group is P21212. We can solve the structure with MR and refine to R=0.233 and R-free =0.276 at 2.25 Angstrom resolution. The maps look very good, but do not suggest major additional modeling that could be done to improve the structure and lower the R-factors. I know that one expects the R-factors from refinement to be higher when TPS is present, but my question is how high is too high? Has anyone done a study that shows the expectations for R-factors when TPS is present? Thanks, Jack John J.

Dear Colleagues, This is a reminder for the upcoming CCP4/APS school. The deadline for registering is coming up soon, please register if you plan to attend. Thanks. Charles, Garib and Qingping ====original announcement ==== Dear Colleagues, We are pleased to announce the *11th annual CCP4 crystallographic school *“From data collection to structure refinement and beyond” will be held on June 18-25, 2018 at Advanced Photon Source (APS), Argonne National Laboratory (ANL), near Chicago, Illinois, USA. All details can be found at http://www.ccp4.ac.uk/schools/APS-2018/index.php. *Dates*: June 18 through 25, 2018 *Location*: Advanced Photon Source, Argonne National Laboratory, Argonne (Near Chicago), Illinois, USA The school comprises two parts: *data collection workshop* and *crystallographic computing workshop*. Data collection workshop includes beamline training, data collection on GM/CA@APS beamlines 23ID-D and 23ID-B equipped with Pilatus3 6M and Eiger 16M detectors respectively, and data processing. For data collection, only the participants' crystals will be used. Crystallographic computation workshop will feature many modern crystallographic software packages taught by authors and other experts. The daily schedule will be organized in three sections – lectures, tutorials, and hands-on (interactive trouble-shooting of the technical difficulties the participants face in their projects). We have had considerable success resolving these problems in past years, attested by resulting publications (see http://www.ccp4.ac.uk/schools/APS-school/publications.php). *Applicants*: Graduate students, postdoctoral researchers and young scientists at the assistant professor level, along with commercial/industrial researchers 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 *Wednesday May 2nd, 2018*. The application form, the program, contact info and other details can be found at http://www.ccp4.ac.uk/schools/APS-2018/index.php *Registration fees*: The registration for application is free but there is $500 participation fee for the selected academic students and $950 for the industrial researchers. The link for the on-line payments and instructions will be provided once the selection process is completed. The students will be responsible for their transportation and lodging. The workshop organizers can assist in making the lodging reservations at the Argonne Guest House. The workshop will cover all other expenses (including meals). We hope to see you at the school. Charles, Garib and Qingping

Dear all I'm having issues on running Phenix. It installs smoothly (I downloaded the point-and-click 64-bit version), but when I try to open, the prompt writes very fast and closes by itself. I tried installing and running on administrator mode and on compatibility mode for Windows 7, but still no good. Below are my laptop configuration: Processor: Intel Core it-7500U CPU @ 2.70 GHz 2.90 GHz RAM: 8 GB System: Operational based on 64 bits, processor x64 Please, could anyone help me? Any guesses? If you need any more information, let me know. Best Regards, Plínio. -- Dr. Plínio Salmazo Vieira Laboratório Nacional de Ciência e Tecnologia do Bioetanol Centro Nacional de Pesquisa em Energia e Materiais Campinas - São Paulo
