Phenix windows distortion windows
by Dmitry Semchonok 28 Dec '23

28 Dec '23

Dear colleagues, I am not sure of the reason, but when I run Phenix, I get the following distortion of the Phenix window. Then, the distortion disappears if I move the cursor somewhere else and click somewhere out of the Phenix window. (please see attachment) Do you know the reasons and how to fix that? Phenix version - 1.21-5187 WSL Windows 11 I will try to 1. roll-back windows drivers 2. update Phenix Kind regards, Dmitry

real space refinement of the model in cryo-EM map
by Dmitry Semchonok 27 Dec '23

27 Dec '23

Dear colleagues, Does anyone know how to improve the Ramachandran plot Z score (Rama-Z)? Ours seems to be too good (low) 🙂 Is there any cure in Phenix for that? Maybe changing certain parameters/restraints can aid? Thank you. Kind regards, Dmitry

Two-year postdoctoral position in time-resolved crystallography at IBS in Grenoble
by Elke De Zitter 22 Dec '23

22 Dec '23

Dear all, We have an immediate opening for a two-year postdoctoral researcher in SNaX team of the DYNAMOP group at the Institute for Structural Biology in Grenoble (France). The successful candidate will work on the development and optimization of bio-scavengers towards toxic organophosphorus compounds. To attain this goal, the researcher will use time-resolved crystallography and in silico protein design methods. The position is funded by the French National Research Agency via the University Grenoble Alpes, and is open for a young researcher. Applicants must have obtained a Ph.D. in structural biology, biochemistry, biophysics, physics, chemistry, or a related field, no more than two years before the start of the project. The candidate must show a track-record of publications in peer-reviewed journals, and is expected to be proficient in English and highly motivated to learn new skills. The candidate will work in the multidisciplinary DYNAMOP group and thus needs to be a good team player as well as being capable of working independently. While the research will be carried out in English, non-French-speaking candidates are expected to learn the basics of French in order to facilitate communication and integration into the laboratory. Experience with one or more of the following skills would be highly evaluated: protein design or the usage of artificial intelligence for structural biology, protein expression and purification, protein crystallization and macromolecular crystallography, serial crystallography, programming or scripting. Interested candidates can apply via [ https://emploi.univ-grenoble-alpes.fr/offres/doctorants/postdoctoral-resear… | https://emploi.univ-grenoble-alpes.fr/offres/doctorants/postdoctoral-resear… ] . We advice to contact Elke De Zitter ( elke.de-zitter(a)ibs.fr ) to obtain more information about the postdoctoral position and application procedure. All the best, Elke Elke De Zitter Institut de Biologie Structurale - IBS group DYNAMOP 71 avenue des Martyrs 38044 Grenoble Cedex 9, France +33 4 57 42 86 56 elke.de-zitter(a)ibs.fr

unassigned densities
by Dmitry Semchonok 18 Dec '23

18 Dec '23

Dear colleagues, Is there a way to assign cryo-EM densities not included in the model sequence? Do you have any tools that can help? More closely, is there a way to screen the cryo-EM map + model, point out the unassigned densities, and provide the possible structures to fit in (e.g., water molecules, etc.)? Thank you. Kind regards, Dmitry

math behind beamstop_shadow_outliers
by Gao, Yunyun 13 Dec '23

13 Dec '23

Hi everyone, While I can find references for other outlier rejection options in scaling.outlier_rejction, there is none for beamstop_shadow_outliers. I am wondering what is the math behind z_lim_ac and z_lim_c. Another question would be: Does the same criteria also apply for the medium-resolution (e.g. 6-8 A) reflections? (like reflections under the beamstop support) Thanks! Best regards, Yunyun ------------------------------------ Yunyun Gao, Dr HARBOR Universitaet Hamburg Tel +49 (0)40 42838-3685

Bug in optimize weights
by Mark Saper 08 Dec '23

08 Dec '23

I am running build 5156 on macOS 13.6.1. I am refining a multi-molecule with imperfect NCS. When I tried to use "Optimize X-ray/sterochemistry" and "Optimize X-ray/ADP weight” the program aborted with an error during the first cycle. The error was: ====================== XYZ individual (reciprocal space) ====================== AttributeError I submitted a bug report via the internal bug report system. I would appreciate how to get around this problem. Should I try the previous stable version? Many thanks, Mark _____________________ Mark A.

Reference model problem
by Luca Pellegrini 06 Dec '23

06 Dec '23

I am trying to use a reference model in real_space_refinement, but phenix stops with the message: “Cannot not restrain working model to self and a reference model simultaneously” (see below). The reference and working models are identical but bound to different ligands. As far as a I can see, all I am doing is adding the reference model in the input window and ticking the box for reference model restraints (phenix 1.21rc1-4985). Best wishes, Luca Luca Pellegrini, PhD Department of Biochemistry University of Cambridge Cambridge CB2 1GA UK [cid:[email protected]]

Error 1.21rc1-5156 macOS and cross special position
by Xavier Brazzolotto 01 Dec '23

01 Dec '23

Dear Phenix developers, I have recently updated to macOS Sonoma and updated Phenix to the latest RC (1.21rc1-5156). I do have recent data where a residue gets a bit too close to its symmetric mate. In order to be able to start the refinement, I have to select the model interpretation option « allow_polymer_cross_special_position=True » In this case, the refinement process starts and does my 3 refinement cycles. However, the UI gives me a final error message stating that I have to enable the « cross-special position » (which is already True). The refined data are present (pdb, mtz, log, cif, eff, geo) but I do not get any analysis on these data. No _info.txt, no .kin files. The log ends with a « Sorry » If I deliberately move the faulty residue a bit out of its position (no more clashing with its symmetric mate) and NOT allow the cross-special position, then the refinement ends well with the correct final data analysis. Not a big deal per se, but but I suspect a small issue in the initiation of the analysis programs (Molprobity / King / etc…). Xavier
