Silhouettes only on selected models
by Pedro Bule 06 Mar '24

06 Mar '24

Hi, I'm writing to know if there is a way to turn on the silhouette graphical option only on selected models in ChimeraX, or is it just a global option? I have a model of an enzyme with its ligand and another model with the electron density loaded from a .map file. I want to display the electron density around the ligand as a slightly transparent mesh without silhouettes (see below) while still having silhouettes on the enzyme and ligand. Is there a way to do this? The silhouettes on the mesh make it too dark and dense (see image 2).

Connection to GPU

Hello, I am trying to build a multimeric structure using AlphaFold collab, but it is not connecting to the GPU. How can I get a connection? Is there a fee for this? How to pay for this? Thanks for your help. Minu Chaudhuri, Ph.D. Meharry Medical College Nashville TN 37208 USA

Hello, I would like to use ChimeraX, but the FDA IT administrators will not download the Chimera X software without a statement about its Section 508 compliance for users. Would you please send me available Section 508 compliance information for this software? Thank you, Carol Weiss

Improvement suggestion: single letter code for swap
by Vorländer,Matthias Kopano 05 Mar '24

05 Mar '24

Dear ChimeraX team, A small feature request: It would be helpful if the swapaa command could accept the single letter code for amino acids as well as the three letter code. This makes it easy to quickly fix a sequence, i.e based on a sequence that is open in the sequence viewer. Many thanks, Matthias

Mainchain and sideonly atom names
by Sabrina Moffit 05 Mar '24

05 Mar '24

Dear ChimeraX team, So far I've found that these are the atom names classified as mainchain atoms by ChimeraX: ['H3', 'HA2', 'H2', 'CA', 'H', 'H1', 'HA', 'C', 'O', 'HA3', 'OXT', 'N'], by using such command: sel #1 & mainchain; info atoms sel. I'm not sure if there are more atom names classified as mainchain atoms by ChimeraX. Could you please provide me with a comprehensive list of all the atom names of the mainchain atoms (and sideonly atoms as well, if possible) of all types of amino acids? Thank you.

Conctac map in ChimeraX?
by PABLO HERRERA NIETO 05 Mar '24

05 Mar '24

Hi everyone, I started using chimera after some years. In the new ChimeraX I could not find an option to calculate contact/distances heatmaps for proteins or protein complexes. Is that old funcionality gone for good? However, to check AlphaFold's pLLDT there is a really nice intereactive chart. Is there any option/hack to use that to visualize contacts/distances for any structure? Thanks Pablo -- Pablo Herrera Nieto Dpto. de Estructura de Macromoléculas, lab 15 Centro Nacional de Biotecnología - CSIC

movie record / encode
by Enrico Martinez 05 Mar '24

05 Mar '24

Dear ChimeraX users! I noticed that there is some difference in the quality of the molecular movies produced in Ubuntu or MacOSX environments. Are there some tricks to improve the quality of the animation produced on ubuntu ? Here are the commands which produced the best results: movie record size 1920,1080 supersample 4 movie encode format h264 quality higher bitrate 25000 how could I modify / add something more with the aim to obtain the best molecular animations ?? Yours sincerely Enrico

Question
by 张楠 04 Mar '24

04 Mar '24

Dear developers, I have a question I'd like to ask. The structure after refinement appears as helices when opened in PyMOL, but in ChimeraX, it doesn't display as helices, as shown in the figures. What could be the reason for this? Is there a way to make it display as helices in ChimeraX? Looking forward to your answer, thank you！ Best regards, Nan 张楠 zhangnan(a)nankai.edu.cn

right-mouse clipping
by Daniel Larsson 01 Mar '24

01 Mar '24

Hi all, I have some question and comments regarding the very useful right-mouse Clipping tools. I feel they are poorly documented (or documentation is very difficult to find by Google searching). For the Clip tool, it took me forever to realize how to “undo” the clipping (click again). The Zone clipping is a very nice feature, which shows atoms, residue labels and volume inside of an approximately 10 Å sphere and hides the volume and only show cartoon outside of the sphere. Right-clicking on the background hides the labels. Some questions 1. How do I change the back/far clipping plane using the Clip tool (the icon suggests that you can clip into a slab)? 2. If so, is it possible to set a default thickness of that slab? 3. Is it possible to change the radius of the Zone clipping tool? 4. Is it possible to disable the cartoon outside of the sphere of the Zone clipping tool? 5. Alternatively have the ability to have an extra front clipping plane, which “intelligently” follows the camera when zooming in (hiding things closer to the centered region when zoomed in more)? 6. I use the mouse mode to center the view and camera pivot point (mousemode middleMode "center or translate"). It is possible to make the Zone clipping tool also center the view + pivot point so that I don’t have to also middle-click every time?
