ChimeraX question
by Amita Mohan 16 Apr '24

16 Apr '24

Hello, I would appreciate if you please answer the following questions: 1. I am using chimeraX, and I have a trouble getting results from Alphafold. The Google Colab keep on termination without saving results. Could you please help? 2. I am using hydrogen bond tool, how can I save all the H-bonds in the protein as file containing all the information for the paired residues involved in the H bond. Similarly, I also would like to save the information of residues involved in the protein-protein interactions. I hope to hear from you. Best, Amita Department of Biology University of Pennsylvania

align the atoms
by 化工化工 16 Apr '24

16 Apr '24

Dear Professor： Hello, I have aligned the atoms #1 of different models with the command "align #1:1 toAtoms #2:1", but I found that the atoms #1 don't overlap very well, which affects the aesthetics of the publication. So, I would like to ask you if there is a way to align the green atoms in the center, thank you very much (see Figure 1)! 化工化工 1366924572(a)qq.com

Hello, I am a relatively new user of ChimeraX. I would like to be able to run commands on chimerax 'headless' by passing them from python. When I used 'from chimerax.core.commands import run' within the python program, I get the error 'ModuleNotFoundError: No module named 'chimerax''. I am using a MacOS 13.5 and the version of Chimera I have installed is 1.7.1 Any help is much appreciated. Thank you Antony -- Antony M Jose [he/him/his] Associate Professor, Department of Cell Biology & Molecular Genetics, Director, MOCB Concentration Area - Biological Sciences Graduate Program University of Maryland, Rm 2136, Bioscience Research Building, 4066 Campus Drive, College Park, MD - 20742.

hide silhouettes for pseudobonds and mesh
by Daniel Larsson 12 Apr '24

12 Apr '24

Hi all, Is it possible to specifically hide silhouettes? The “graphics silhouettes” command unfortunately does not take a spec argument. One example is to hide it for the mesh when you want to show the model and the map at the same time. Silhouettes around the mesh can make the scene look very cluttered. For this particular case, my colleague showed me a trick to use the selection command instead of “graphics silhouettes” and change the appearance of the selection, e.g. “graphics selection color black width 1”. But it gives slighly different apperance with far clip planes, where silhouettes are truncated while selections are enclosing clipped elements, removing some of the depth illusion from the mist. Another scenario is for pseudobonds, e.g. when displaying cartoon and mainchain atoms at the same time using the trick with “cartoon suppress false; cartoon tether opacity 0” given in this thread https://mail.cgl.ucsf.edu/mailman/archives/list/chimerax-users@cgl.ucsf.edu… I like to have the cartoon visible to guide the eye where the main chain goes, but I do not want the pseudo bonds to be visible since that adds clutter and is confusing. But the silhouettes command will outline the connections to the ribbon for the C3’ and C4’ atoms in nucleic acids.

chimeraX silhouette look spotty
by kellychen52071＠gmail.com 11 Apr '24

11 Apr '24

Dear ChimeraX support team, I'm experiencing an issue with ChimeraX silhouette showing dark spots. I’m using ChimeraX version 1.7.1. Please see the picture attached. Could you please help me resolve this? I’m using the latest version of macOS Sonoma 14.4.1 (graphics: intel iris plus graphics; processor: 2GHz Quad-core Intel core i5) Is this a graphic issue, this may be a ChimeraX bug for the newest version of mac as my peers who are using an older version of mac do not have this ChimeraX issue.

Mesh settings in ChimeraX
by Matthew Hancock 11 Apr '24

11 Apr '24

Hello, I have a density map I am visualizing as a mesh in ChimeraX. If I recall there are settings to manipulate the mesh visualization (line width, antialiasing, etc.) but I cannot them. If they exist, where might I find them? Thank you. Best Matthew

Dealing with netcdf trajectories
by Enrico Martinez 11 Apr '24

11 Apr '24

Dear Chimera-X users ! Typically having loaded pdb of the system I use the following command to load the netcdf file, which replaces current pdb with the trajectory: open ./trajectory_part1.nc structureModel #1 would it be possible to load in the same section the second part of the same trajectory and merge the both into the same ensemble ? E.g. if I run subsequently the same command with another trajectory, it will produce another ensemble related to the second trajectory (and not merge the both together): open ./stripped_*part2.nc structureModel #1 Many thanks in advance! Enrico
