Dear ChimeraX, Does chimera-X come with an IDE to edit and run python scripts?, something like IDLE in Chimera? Thanks Hernando ___________________________________ Hernando Sosa, PhD.

Re: [Chimera-users] Changing threshold value of attributes

Hi Abril, There are separate mailing list for Chimera and ChimeraX, so you should send ChimeraX questions to chimerax-users(a)cgl.ucsf.edu <mailto:chimerax-users@cgl.ucsf.edu> . The problem you ran into has been fixed and the fix is in the 1.7 release candidate, so if you use that then things will work. --Eric Eric Pettersen UCSF Computer Graphics Lab > On Nov 28, 2023, at 10:25 AM, Abril Gijsbers via Chimera-users <chimera-users(a)cgl.ucsf.edu> wrote: > > Dear community, > > I want to render my model by attribute and change the thresholds (up and bottom limits).

volume amount estimation
by Jesse Hansen 04 Jan '24

04 Jan '24

dear ChimeraX users, We have a tomogram volume (.mrc) which we have segmented different components (stl files; surfaces). Is there any tool available to estimate the volume within each of the cellular components (within each surface)? Either some approximation of the cubic Angstrom/nanometers, or as a percentage of the total tomogram volume. thanks in advance! best Jesse Hansen

Hi guys, Happy new year. I came across this https://www.schrodinger.com/3d-visualization-looking-glass-holographic-disp… . Can we look forward to having this compatible for chimerax since we are having difficulty finding 3D stereo displays for structural biology.

Tile behavior in Chimera vs ChimeraX - different behavior of independent rotation?
by Oliver Clarke 04 Jan '24

04 Jan '24

Hi all, Happy new year! I have some observations/queries regarding the "tile models" command in Chimera vs ChimeraX. In Chimera, the rotation mode is not linked to a specific mouse mode - so if I change it from "front center" to "independent", this will affect rotation of models regardless of how I do it - whether using the mouse, the trackpad, or using the rock, roll or turn commands on the command line. In ChimeraX, independent rotation is now a separate mousemode - so it only applies to whatever mouse mode (e.g. left mouse) one has it applied to, and does not apply to the trackpad or command line. Is there any prospect of altering this behavior, or mimicking the old behavior? When tiling many models (or maps) for comparison, I like to view them with a rocking motion to give better 3D perception, but now I can't do this (it just rocks the entire "plane" of dispersed models, rather than each independently). Cheers Oli

Problems with installation

Good Evening I wanted to asked about compatibility and installation issues. I am currently using a Chromebook with Linux Debian 11 (Bootstrap) and I am trying to get ChimeraX 1.7 installed onto it. I keep coming into errors when I try to run it by the way specified on the site. For info: " Download is a tarball of the chimerax application directory. Make symbolic link to executable in chimerax/bin/ChimeraX. Do not put on path. It may require additional libraries and/or older versions of libraries to be installed.

Recover unsaved ChimeraX session?

29 Dec '23

Dear all, happy Holidays! I am not very optimistic about this one, but I will just drop the question here and it may simply be that I am unaware of this function: I had a ChimeraX session crashing just when I was about to save it for the first time... is there any way to recover unsaved ChimeraX session, such as temporarily saved files? Thank you, André

28 Dec '23

Hello Chimerax, I hope you're well:). Towards the above subject, SwissParam has recommended UCSF Chimera to convert my pdb to a Mol2 File for SwissParam subsequent parameterization, however, I could not discover this webpage within your UCSF Chimerax Website? Thanks if you can clarify how I may generate this Mol2 via yout Chimera if able. Best, Joel 🚀
