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

ISOLDE on Mac M1/M2/M3 or on Linux CentOS 7
by Mark Hilge 05 Dec '23

05 Dec '23

Hello, Could you please tell me whether your latest Version of ISOLDE would either run on a Mac with an Apple Silicon chip (M1, M2, or M3) or on a Linux box with CentOS 7 installed? Many thanks in advance! Kind regards, Mark

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!

"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.

How to save a sequence in an mmCIF file?
by Guillaume Gaullier 29 Nov '23

29 Nov '23

Hello, Starting from an AlphaFold prediction, I refined a model against a map with ISOLDE. I trimmed the segments not supported by any density. The resulting mmCIF file that I saved now opens with this warning: Unknown polymer entity '1' near line 187 Missing or incomplete entity_poly_seq table. Inferred polymer connectivity. Displaying the sequence of this chain shows the correct numbering (with jumps in numbering according to missing segments in the structure), but the sequence of the missing structure segments is not displayed. When I open the fasta file containing the full-length sequence, the sequence gets automatically associated to the structure, and the sequence viewer annotates the segments with missing structure correctly. I would like to save this full-length sequence in my mmCIF file so the full-length sequence with annotated missing structure segments shows up next time I open this file. But when I try to save at this point, I get the following notice: Not saving entity_poly_seq for non-authoritative sequences The documentation for "save" and "sequence" didn't help. How can I make this sequence "authoritative" and save it into my mmCIF file? Thank you in advance, Guillaume När du har kontakt med oss på Uppsala universitet med e-post så innebär det att vi behandlar dina personuppgifter.

transition dipole moments
by gennaro.pescitelli＠unipi.it 28 Nov '23

28 Nov '23

Dear developers, first of all, thnak you for your great software, I just started using it. My question: is there a way to plot transition moments (electric and magnetic), as calculated e.g. by TD-DFT calculations in ORCA or Gaussian? If not directly from a log/out file, is tehre a way to manually add a vector arrow? Thanks Rino Pescitelli
