treating the water molecules in the model
by Dmitry Semchonok 20 Jan '24

20 Jan '24

Dear colleagues, Please share your experience with how you handle the water molecules. So, we have a refined model and added the water molecules using the Douse protocol. So, should we refine the model again afterwards? Or is the model considered ready? We tried to refine our model with water, but then the water molecules flew away from the places. Please let me know what is the correct way to proceed. Many thanks for considering my request. Sincerely, Dmitry

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

That is, 1) Extract sonoma_fix.tar.gz 2) cd sonoma_fix 3) sudo ./fix_wxpython.sh /Applications/phenix-1.19.2-4158 Inside the sonoma_fix directory, there should be a "bin" directory with conda.exe. The installed versions of Phenix do not come with conda. The fix comes with a standalone version of conda that can modify the Phenix environment with the dependencies. Let us know if it's still not working. Thanks! -- Billy K.

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
