Phenix does not start
by Cygler, Miroslaw 11 Jan '24

11 Jan '24

Hi, I have recently upgraded my MacBook running M1 processor to the Sonoma 14.2.1 operating system. Now, when I tried to start Phenix GUI, a message pops up: “python quit unexpectedly” and guy does not open. Any advice would be helpful. Regards, Mirek

Input from the community for panel session: Crystallography is Dead! Long Live Crystallography!
by Nicholas Pearce 02 Jan '24

02 Jan '24

Hello, and happy new year! [and absolutely no apologies for cross-posting 😉] Tomorrow evening, we will have a panel discussion at the CCP4 study weekend about the future of crystallography, called “Crystallography is Dead. Long Live Crystallography!” [https://en.wikipedia.org/wiki/The_king_is_dead,_long_live_the_king]. Whether you’re attending the CCP4SW or not, we want to hear from the community about your thoughts on the subject (see the blurb below), so that we can discuss things the community is most interested in! if you have a few minutes, please do fill in the form (all questions are optional): https://forms.office.com/e/3K5qSMNpYh. Thanks, and looking forward to seeing some of you very soon! Your friendly neighbourhood scientific organisation team, Nicholas Pearce, Helen Ginn, and Clemens Vonrhein Blurb: In this session, we will discuss the current state and the future of crystallographic experiments in the context of structural biology: * what are the unconfronted problems that the field still faces? * what problems are now essentially solved? * where should future method development be focussed? * what challenges are emerging from new experimental developments? * do new experiments provide new perspectives on old problems? Inevitably, this will include discussion of whether these challenges are likely to be addressed by the application of recent advances in AI, and, with the continued developments in cryoEM, what is crystallography's role as a part of the structural biologist's toolbox? Panel Chair: Elspeth Garman Panel Members: Dave Brown, Arwen Pearson, Ashwin Chari Please submit questions for consideration during the panel discussion using the form below! and we look forward to seeing you on 3rd Jan! Some of the questions are asked mischievously - you are welcome to have some fun with your answers! All questions are optional! https://forms.office.com/e/3K5qSMNpYh

Re: [phenixbb] Phenix installation on macOS 14 Sonoma
by Klureza, Maggie 31 Dec '23

31 Dec '23

Hi all, Reviving this thread (or trying to, anyway - TBD if I can successfully reply to a thread begun before I'd joined the phenixbb list!), I recently updated my Mac OS to 14/Sonoma, and am now also having issues getting Phenix to work. As directed on the installers page <https://phenix-online.org/download/phenix/release/>, I downloaded the supplied fix <https://phenix-online.org/download/sonoma_fix.tar.gz>, extracted the tarball, and ran that code as `sudo Downloads/sonoma_fix/fix_wxpython.sh /Applications/phenix-1.19.2-4158`. This was the resulting output/error I got: Password: Removing old version of wxPython ================================ Downloads/sonoma_fix/fix_wxpython.sh: line 36: ./bin/conda.exe: No such file or directory Installing new version of wxPython ================================== Downloads/sonoma_fix/fix_wxpython.sh: line 42: ./bin/conda.exe: No such file or directory The wxPython package has been updated in /Applications/phenix-1.20.1-4487. Sure enough, when I went to my phenix installation and looked in conda_base/bin, there was no file named `conda.exe` present. This was true for both my prior installation (phenix-1.19.2-4158) and when I tried a newly downloaded version (phenix-1.20.1-4487). Can anyone tell me how I get that conda.exe file included with the Phenix download/how else I might be able to run Phenix with this OS? (I sent an email about this to help(a)phenix-online.org before thinking to hunt through the phenixbb archive, so apologies to whoever checks that email and is getting this message twice!) Many thanks, Maggie

geometrical restraints between symmetry related chains
by Jorge Iulek 29 Dec '23

29 Dec '23

Dear all, I am working currently on a structure that should be "peptide bond" between chains, but the "second" part of the chain is in a symmetry related peer. Numbering is continuous and there are justifications to why the chains are separately named with different chain ID's. By the way, this "connection" is "full of glycines" so a kind of flexible, but a continuous stretch can be seen at "reasonable" density (and despite low resolution). To better explain, say I have chain C residue x to be bound to chain K, at symm operation -x-1,y-1/2,-z-1/2, residue x + 1. I would prefer to really refine the presence of these "connecting" glycines, of course with due geometrical restraints imposed (precious at this low resolution). phenix.refine offers: refinement.geometry_restraints.edits at bond with the possibility to indicate the symmetry_operation for the "second atom" within the bond. But this "symmetry_operation" indication is not available (?) for the other geometry_restraints edits, like angle, dihedral, etc. (eventually, planarity might also make easier). Do I miss anything here? Currently, I see 3 possibilities: a) somehow (how?) I can add angle, dihedral restraints in involving chains in symmetry related operations b) I bring the symmetry related chain to its non "symmetry related" position and change chains names/residues ID, etc., so I go into this go/return of naming at each step of the refinement work/analysis c) I add "extra" ( + - like alternate conformation residues) residues to each end of the connection, such that these extra residues will receive due conventional geometrical restraints (as phenix.refine does for contiguous residues in a chain) but I force them to be on the same position (and probably declare 0.5 occupancy for these overlying residues). "a" should be the easiest, if available somehow; "b" would be cumbersome during the refinement/analysis process; "c" seems to be the most complex but maybe the best if it works. Nevertheless, someone might have an easier suggestion. Thanks, Jorge

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
