Following Up on Drawing Outlines
by Andre Leon 07 Dec '23

07 Dec '23

Hello Chimerax, I was wondering if there has been any progress on making outlines of specific epitopes in ChimeraX since this thread back in 2014?<https://www.cgl.ucsf.edu/chimera/data/outline-may2014/outlines.html> Thank you in advance. Best Regards, André Nicolás León Graduate Student - Ward Lab<https://ward.scripps.edu/> https://www.linkedin.com/in/andrenicolasleon/

Add charge to PDB fails
by Daniel Hsu 06 Dec '23

06 Dec '23

Hi All What might cause this action to fail, pH=7.4, H added to protein before adding charge? No errors were thrown. Both DOCK-Prep, and adding H then charge both do not change the PDB file (no charges added to respective atoms). Log reports "Using Amber 20 recommended default charges and atom types for standard residues" Alternative command 'addcharge standardizeResidues 5BU,CSL,MSE,UMS' reports "Using Amber 20 recommended default charges and atom types for standard residues" and no errors but don't add charges to saved PDB file. Charges are added with another structure editor.

Surphace representation of multi-model pdb and moovie recording
by Enrico Martinez 06 Dec '23

06 Dec '23

Dear Chimera-X users ! I am working on molecular visualization of membrane system from the md trajectory loaded in the Chimera-x using the open coordset true command. The issue is with the surface representation of the membrane: transparency :OL,PA,PE,PC 80 target s which are applied only on the current frame (not on the whole trajectory). Also when I try to make a movie of the system the presence of the surface does slow down everything. Which options could be useful e.g. to decrease the quality of the surface representation ? Many thanks in advance Enrico

ChimeraX & ConSurf
by martin.brehm＠univie.ac.at 05 Dec '23

05 Dec '23

Dear ChimeraX developers, I have a question regarding a potential upgrade of ChimeraX. Would it be possible to include the functionality of ConSurf, a tool to plot the degree of sequence conservation onto a model, into ChimeraX? The code for this is publically available on GitHub: https://github.com/Rostlab/ConSurf See this publication for more information: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4987940/ Thanks a lot in advance and have a nice day! Best regards Martin Brehm Martin Brehm - PhD Student Falk Lab - Max Perutz Labs Vienna Room 1.624 - Phone +43 14277 74361 martin.brehm(a)univie.ac.at

Missing tools in ChimeraX
by Lars Backman 05 Dec '23

05 Dec '23

Hi, In Chimera, a tool named “Viewing” was available. It was an excellent tool to adjust appearance of the final png or jpg figure. I have looked for a similar tool in ChimeraX, but it seems to be absent. Or is there a way to create something similar?

Exporting scene with .obj and .mtl file
by Berndsen, Zachary 04 Dec '23

04 Dec '23

Hello, I need to export an obj file along with the associated mtl file, however, under the “file > save” option, there is only an option for saving as .obj, not .mtl. I read in the online documentation that there should be the capability to “export a scene” which saves an obj and mtl file, however I do not see this option when using v 1.6.1. Is this still supported? Thanks, Zack

Python Function that implements the "center" method from the GUI
by tong.you＠icm.uu.se 01 Dec '23

01 Dec '23

Hello, For an automatic pipeline workflow, I want to have a way to center several mrc files using the Python module. However, I can't seem to find the corresponding Python function that I can use in a script to "center" an opened map. Is there a Python function to "center" a map similarily as in the GUI? Kind regards, Tong

Independent movement of chains in movie
by Caroline Stone (JIC) 30 Nov '23

30 Nov '23

Dear ChimeraX team and list subscribers, I am making a little movie to show a complex of two proteins, but am stuck on individual movements of chain /A and /B. If I use the move command, chain /A and /B both move independently, away from each other: move x -10 atoms /A; move x 10 atoms /B However, if I attempt to do the same movement by going -1 or +1 over a series of 10 frames, I no longer get any movement of /A and /B. move x -1 10 atoms /A; move x 1 10 atoms /B I can achieve movement over a number of frames, but both chains move although I tried to specify only /A. I did this based on "move axis [ distance [ frames ]]". move x -1 10 atoms /A I feel I might be on the right track because when I use turn, I am able to trigger simultaneous independent rotation of /A and /B around their own axes (thank you for this feature by the way, last time I wondered about this it wasn't possible). cofr /A; turn y -1 90 atoms /A; cofr /B; turn y 1 90 atoms /B My ultimate goal is to open the binding interface up a bit like opening a book. I suppose I could achieve a similar effect by setting the centre of rotation for each chain behind, rather than within - if independent movement over a series of frames isn't possible, I might experiment with that. I updated to version 1.6 and searched the list, but I still see this behaviour with the move command. Perhaps I am missing something basic? Thank you for any pointers you might be able to share! Caroline

"view" in command line vs. menu
by C. Klein 30 Nov '23

30 Nov '23

Dear Eric, Oliver, et al. you may remember my comment on the missing "focus" function. Anyhow, what I noticed now is interesting: The function of the "view" command is different in the menus vs. the command line. in the command line, "view" will zoom out and show everything in the menu, "view" will focus on the selected ligand or whatever (which is what I want a bit more, mostly) Perhaps this could be resolved with modified or rather re-surrected terminology: Focus on selection: "focus" in command line "focus on selection" in menu Zoom to fit all: "zoomall" in command line "zoom to fit all" in menu just some suggestions. But what I think is clear is that the function of commandos should be identical in menu and command line. Again, thank you very much for your important and good work on the Chimera software.
