Announcement: SpringerBriefs in Crystallography
by Dorothee Liebschner 28 Jan '19

28 Jan '19

Hi everyone, I would like to circulate the announcement of a new series of crystallography monographs entitled “SpringerBriefs in Crystallography” ( https://www.springer.com/series/16236). Areas of interest include structural biology. The announcement below is on behalf of the editor-in-chief, Prof. M. Nespolo. Best wishes, Dorothee Liebschner Series editor for biological crystallography, SpringerBriefs in Crystallography ========================================= Dear Colleagues, It is my pleasure to announce the launch of a new series of crystallography monographs under the title “SpringerBriefs in Crystallography”. They cover a new discipline within the “SpringerBriefs” collection, which publishes concise monographs with an intermediate scope ( https://www.springer.com/gp/authors-editors/book-authors-editors/springerbr… ). SpringerBriefs already covers 84 fields spanning a wide range from natural sciences to law, social sciences and more; crystallography is now the 85th field. The new series is published under the auspices of the International Union of Crystallography and all the manuscripts will be peer-reviewed by the series editors, as well as external reviewers when necessary. It takes an intermediate and so far uncovered place between articles published by the IUCr journals and full monographs. The IUCr publishes several types of articles in its journals (https://journals.iucr.org): • Research Papers, which are full-length manuscripts that normally do not exceed 15 journal pages (about 15 000 words); • Short Communications, for the presentation of topics of limited scope or for preliminary announcements of novel research findings; • Lead Articles, authoritative, comprehensive and forward-looking reviews of major areas of research interest (by invitation); • Feature Articles, focused surveys covering recent advances in an area of current research, which do not aim to be comprehensive, and are generally about ten journal pages (10 000 words); • Topical Reviews, which aim to capture the current trends of a field and are expected to be relatively short (about 6000 words and a maximum of 50 references, with half of those having been published in the last three years); • Letters to the Editor, which may deal with non-technical aspects of crystallography, its role, its propagation, the proper function of its Societies etc. • Scientific Commentaries, which discuss articles of particular importance for the readership of the journal. Full monographs spanning hundreds of pages are published in the IUCr/OUP monographs, and textbooks in the IUCr/OUP texts (https://www.iucr.org/publications/iucr-oup). SpringerBriefs in Crystallography aims at publishing shorter monographs, typically between 50 and 125 pages, where specific topics are dealt with more in detail with respect to what one could do in a Lead Article or Topical Review, in particular with a more pronounced accent on the background. Also, more space is given to some fundamentals which would not find place in a Lead Article or Topical Review, with the aim of providing the reader a more pedagogical introduction (whenever suitable) without the need to look for it in a separate text. Publications in this series help support the Outreach and Education Fund for the International Union of Crystallography (https://www.iucr.org/iucr/sponsorship/iucr-outreach-fund). The website of the new series is available at the address https://www.springer.com/series/16236, where you find more details as well as the responsible editor contact information, who upon request can provide you with a proposal form. On submission the responsible editor will then forward it to the series editors for discussion and approval. Please, feel free to forward this information to your colleagues who may be interested in publishing a monograph in this series. -- Project Scientist, Molecular Biophysics and Integrated Bioimaging Lawrence Berkeley National Laboratory 1 Cyclotron Road, M/S 33R0345 Berkeley, CA 94720 Tel: (510) 486-5709 Fax: (510) 486-5909 Web: https://phenix-online.org

ISOLDE 1.0b2 release
by Tristan Croll 24 Jan '19

24 Jan '19

Dear structural biology community, I am very happy to announce that ISOLDE 1.0b2 is now available. All the details including documentation are available on the new ISOLDE website at https://isolde.cimr.cam.ac.uk, but the following is a short list of new features and improvements since ISOLDE 1.0b1: - added support for Windows. ISOLDE is now available for all three major operating systems. - many usability and stability improvements. In particular, ISOLDE is now much more helpful when your starting model is not yet quite simulation-ready. - No more need to delete unparameterised residues from your model. You can now choose to have ISOLDE simply ignore them for simulation purposes. - Real-time smoothing of the trajectory visualisation to reduce thermal jitter. - Direct handling of real-space maps (no need to convert them to structure factors first). - Live recalculation of structure factors and crystallographic maps from F/sigF data as model coordinates change. I do hope you find it useful. Best regards, Tristan

Iron–sulfur clusters have no right angles Nigel W. Moriarty and Paul D. Adams, Acta Cryst. (2019). D75, 16–20 <http://journals.iucr.org/d/issues/2019/01/00/rr5165/index.html> This agrees well with what we see in structures of respiratory complex II!

Refining an ion on a special position
by Shane Caldwell 11 Jan '19

11 Jan '19

Hi phenixbb, I've got a question related to refinement of an ion on a special position. I have a structure with an atom placed squarely on the C2 axis. I've been able to get a mostly-reasonable model by dropping in the ion at 0.5 occupancy and turning off repulsion for the ion in question, as Pavel describes here <http://www.phenix-online.org/pipermail/phenixbb/2018-February/023689.html>. It almost completely works. The thing I find now is that during refinement there can still be some random drift of the atom away from the symmetry axis, splitting from its symmetry ghost, while I know that it should stay perfectly coincident. My resolution is 3.1 and there's no indication of a multiple conformation, so a split isn't justified. The most parsimonious model should place the ion exactly on the C2. Is there any way to enforce that either 1. x, y = 0.0 in refinement, or 2. the ion is constrained to the xyz of the symmetric version of itself. Both should get to the same place, with the metal precisely on the axis, and precisely over top of it's symmetric counterpart. Thanks!

atoms with unknown nonbonded energy type
by Danilo Belviso 11 Jan '19

11 Jan '19

Dear all, I am refining the structure of a cyclic peptide with having residues that are not in the ligand list of phenix. I would to perform unrestrained refinement by considering the very good resolution of the data. However, also in this case, phenix requires the restrain file of the ligand. I got cif file in two different way: 1) PRODRG server 2) by running phenix.elbow both produce the restrain file with no error message. However, by using such file in the refining, I get this error: Sorry: Fatal problems interpreting model file: Number of atoms with unknown nonbonded energy type symbols: 14 In the cif file, there are not atoms having 14 as energy type symbols. Could you suggest to what this message is referred to? How can I modify the cif to overcome the problem?

Re: [phenixbb] Phenix installation on Debian9.6
by Billy Poon 09 Jan '19

09 Jan '19

Hi Danilo, I have a Debian 9.6 virtual machine running and Phenix is working after en_GB is installed. The problem is with the locale. It looks like en_GB is required even though another language is used. I had to install en_GB even if I'm using en_US. When I have only it_IT.UTF-8 installed, I get the en_GB error. After installing en_GB, the GUI works normally (see attached screenshot, phenix.png). To install en_GB with instructions from https://wiki.debian.org/Locale, 1) open a Terminal and become root 2) run "dpkg-reconfigure locales" 3) Select en_GB.UTF-8 (see attached screenshot, locale.png) 4) Select "OK" and complete process. You'll have to just choose your default language, but you should have it_IT.UTF-8 as your default 5) Verify that en_GB is available with "locale -a" (Mine is shown in a terminal in phenix.png) Changing the setting for Phenix 1) Go to the <phenix installation>/build directory 2) Type "export LC_ALL=it_IT.UTF-8" 3) Run the config_modules.sh script 4) Verify that "LC_ALL=it_IT.UTF-8" is in our programs. In phenix.png, I check that <phenix installation>/build/bin/phenix has LC_ALL set to it_IT.UTF-8 5) Phenix should run and the main GUI should pop up I suspect that because Phenix is not localized, we may be requiring an English language to be installed and maybe en_GB is a default. So in phenix.png, the dates for the projects are in Italian, but everything else is in English. Also, I think our number formatting is not localized, so decimal points will be "." instead of ",". I'm sending the images to you directly since the bulletin board has some size limit and the original message with attached images is waiting approval. -- Billy K.

Dear all, I am intalling phenix on my Debian 9.6. My arch is adm64 thus I downloaded the phenix version named Kernel 2.6 (64-bit; CentOS 6). The installation procedure has been performed as suggested by the guide and no problems were obtained. However, by running phenix (after source phenix_env.sh) I get the follow output with several errors: (main.py:14196): GLib-GIO-CRITICAL **: g_loadable_icon_load: assertion 'G_IS_LOADABLE_ICON (icon)'

Jumping Rfree upon bulk solvent modeling
by Weinert Tobias (PSI) 08 Jan '19

08 Jan '19

Dear PHENIXBB community, i have come across a strange behavior in Phenix: * I copied Rfree-flags from a dataset with very slightly different unit cell * Refined the previously refined model against the new data * Rfactors in first round were good * Second round in refinement Rfree was up by 10 % just from the start during bulk solvent modeling and scaling * In another round Rfree was high in the beginning, and then dropped by those 10 % during bulk solvent modelling and scaling. * In yet another round Rfree started 10% lower than the previous round during bulk solvent modeling in the first cycle and then it jumps up again in the second cycle. What could be wrong? Many thanks and kind regards, Tobias Weinert

mmCIF in Phenix 1.14-3260
by Dominik Oberthuer 30 Dec '18

30 Dec '18

Dear all, I recently found that phenix.refine in version 1.14-3260 generates coordinate mmCIFs that the PDB deposition system can't handle. After struggling with this for some time I used an installation of Phenix 1.13-2998 I still have on my MacBook and used the mmCIF/PDB-conversion tool from this version and had no more trouble with uploading the mmCIF to the PDB. Maybe it is worthwhile to check which changes from 1.13 to 1.14 might have caused these issues. Thanks!

smaller the cell parameter of EM map
by dancingdream＠163.com 29 Dec '18

29 Dec '18

Dear all, The cell parameter of the EM map is always too large, which will make the model building program running very slow. But in factor, the structure is a smal part of cell. So can I smaller the cell parameter when I use phenix.map_to_structure_factors to convert the EM map to mtz file. Thank a lot! Wei

Help with AutoBuild
by Parthasarathy Sampathkumar 15 Dec '18

15 Dec '18

Dear All, These days my research often involves structure determination of the Antigen:Fab complexes, wherein the antigen structure is already known. Given this: (1). I would like to run AutoBuild in such a way that the program does not to touch antigen model, but only Re-builds only the Fab molecule; and (2). in some cases, due to structural-symmetry within the variable and constant domains of heavy- and light- chains, AutoBuild is searching and applying NCS operator while it is not present, and would like to avoid the same. How could these be done either in GUI or in command-line?!! Many Thanks in advance, Best Wishes Partha PS: Of course, when the data is at "high-enough resolution", I build Fab model manually after MR and Refinement. But, in the above case, resolution is only 3-ish angstrom.

speeding up effective resolution calculation
by Eric Williams 07 Dec '18

07 Dec '18

Greetings, all. I have what may be a naive question. :) I'm using phenix.resolution to calculate effective resolution, and I'm looking for ways to speed it up. I've tried a few different machine configurations, and it always takes around 20 minutes per structure. This is problematic for me, because I'm trying to collect data from the entire PDB. Does anyone here have experience using NumPy to optimize scripts and helpful suggestions for this case? Alternatively, how much speedup am I likely to get by rewriting the script in C and using it as a module? Thanks. :) Eric

Hi Boaz, Is it possible for you to send me (and just me, not the bulletin board) your file for testing? Thank you, if so. Alternatively, you can try using our alternate site at http:// altmolprobity .biochem.duke.edu, where a bugfix that probably addresses this issue is currently under testing. Thanks and good luck, -Christopher Williams ---Richardson Lab, Duke University On Fri, Nov 30, 2018 at 11:57 AM Boaz Shaanan <bshaanan(a)bgu.ac.il> wrote: > Hi, > > > I noticed small differences between the molprobity > all-atoms clashscore reported in the output pdb file and the results > reported by the molprobity run (build 3318). > > > Cheers, > > > Boaz > > > > > > > > > > > > > *Boaz Shaanan, Ph.D. Dept. of Life > Sciences Ben-Gurion University of the > Negev Beer-Sheva > 84105 > Israel > E-mail: > bshaanan(a)bgu.ac.il <bshaanan(a)bgu.ac.il> Phone: 972-8-647-2220 > Fax: 972-8-647-2992 or 972-8-646-1710 * > > > > > > _______________________________________________ > phenixbb mailing list > phenixbb(a)phenix-online.org > http://phenix-online.org/mailman/listinfo/phenixbb > Unsubscribe: phenixbb-leave(a)phenix-online.org

Validation Completeness Issue
by Antoine Koehl 29 Nov '18

29 Nov '18

Hi, I’m in the process of uploading data to the PDB. While AIMLESS had estimated my completeness at 94% (similar to the XTriage value of 93.2%), the internal PDB validation through EDS estimates my completeness to be closer to 83.5%. This is a rather large difference. Both are using the exact same resolution range (49.57-4.00). Is there something that EDS does differently for estimating completeness? Please advise, Antoine

Alternate conformer clash problem in phenix.refine
by Aaron Oakley 19 Nov '18

19 Nov '18

Salve! I am refining a protein/ligand complex where the ligand is bound with two conformers. Conformer A is covalently bound to a cysteine residue. Conformer B is free. I have prepared an appropriate cif dictionary for the ligand including info on handling the link. The problem is that during refinement, non-bonded interactions between the two conformers appear to not be switched off and their geometry becomes distorted. Is this diagnosis correct? If so, is there a way to manually switch off interactions? With thanks, a++ Aaron Oakley Associate Professor School of Chemistry and Molecular Bioscience | Molecular Horizons | Faculty of Science, Medicine and Health University of Wollongong NSW 2522 Australia T +61 2 4221 4347 | F +61 2 4221 4287 [cid:[email protected]]

exclude clashes for non-symmetry contacts
by Edwin Pozharski 16 Nov '18

16 Nov '18

Is there some way to make phenix.refine to ignore clashes for specific pair(s) of chains? I am dealing with a rare case of twinning where same protein molecule exists in two orientations in the same unit cell. I tried just to duplicate the molecule and set initial occupancy to 0.5, but refinement fails (as I expected) saying that there are too many close contacts. Ideally, I would like to proceed with ignoring close contacts between, say, chains A/B. I am aware that one can exclude groups of residues from symmetry clashes, but these two copies are in the same cell. I guess I could try shifting one into the next unit cell and then excluding symmetry clashes, but even assuming that will work it is a rather ugly hack. The alternative is probably to define the second orientation as an alternative conformation. Aside from aesthetic objections, I don't want to lose the ability to restrain NCS - I need two orientations to be identical structures, and I am not sure yet whether I can use NCS groups defined via alternative conformers. Cheers, Ed.
