Inquiry Regarding Feasibility of Implementing Protein Operations in Python
by 澁谷まゆ 28 Nov '23

28 Nov '23

Dear UCSF ChimeraX, I hope this email finds you well. My name is Mayu Shibuya, and I am a student at Iwate University, currently affiliated with the wet biology laboratory. I am reaching out to seek guidance on the feasibility of utilizing the software for a specific task. Specifically, I am interested in performing addh and addcharge operations and automating these processes using a Python script. However, I do not know whether the addh and addcharge operations can be executed in Python. Could you kindly provide guidance on the possibility of achieving this with the software? If it is indeed feasible, I would greatly appreciate any instructions or methods you recommend for implementing these operations in a Python script. Thank you for taking the time to consider my inquiry. I greatly appreciate your assistance and look forward to hearing from you soon. Best regards, Mayu Shibuya Iwate University ms04000106(a)gmail.com

hide dust
by Andrea Smith 28 Nov '23

Hi, I have cartoon and map visible for a part of my molecule (one protomer from a tetramer). When I click on hide dust, the dust is hidden but at the same time the map appears for the rest of the tetramer. Is there a way to hide dust around the visible part of the map while keeping a part of the map hidden? Thanks, Andrea

Hi, Would there be a way to save convservation scores from a large multiple sequence alignment into a file that could be re-loaded later instead of having to reload the actual alignment file? In looking at WDFY4, the alignment of the 3124 residue protein from 523 different species, the alignment fasta file takes around 10 minutes to load. After calculating the scores, the program shows the alignment and then the showing the convervations of residues in the protein is my goal of analysis. But it takes the same 10 minutes every time I open the session. I haven't found a way to save the scores themselves and load that in directly. Is there a way to do that? thanks it's a great program. ken murphy ________________________________ The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.

Reading .xyz vs. Orca .out file
by Michael Patzschke 23 Nov '23

23 Nov '23

Dear colleagues, Recently the following problem has appeared: When I open an orca output file and chose the ball and stick option for displaying molecules, the radii of the balls are all wrong. This problem does not show up when I open the corresponding .xyz file. I try to attach an example to illustrate the problem. I would appreciate any help in this matter.

Dialog box after dockprep command in 1.7rc202311210000
by r.m.newlon＠gmail.com 22 Nov '23

22 Nov '23

Hello all, I am on an Apple M1 and have just updated to ChimeraX 1.7rc202311210000. I am just starting to learn how to use ChimeraX from the command line (Terminal). My code that ran from Terminal on ChimeraX 1.6 doesn't seem to be working now with 1.7. Specifically, it seems that the dockprep command now ends by automatically popping up a dialog box prompting you to save a Mol2 file. I think this is causing problems when I try to run in nogui mode. I will include the "error message" at the end of this message, in case it is helpful. If this dialog box is the problem, is there a way to suppress it? Thank you!

Thanks for ChimeraX. I've been loading multiple sequence alignments in fasta format directly into ChimeraX for mapping conservation onto a pdb and it works great. My MSA are directly from clustalo omega and in fasta format not clu formtat. My question is this. My compiled al2co.c as well as the binary I downloaded for al21co.exe doesn't work with input in fasta format. And yet ChimeraX opens and al2co window when I input my alignment. Does ChimeraX use another version of al2co that is configured to open fasta files? thanks for any info. ken murphy ________________________________ The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.

Sequence via remotecontrol?
by Boris Steipe 21 Nov '23

21 Nov '23

Hi all - I am using the fantastic remotecontrol REST interface in teaching, and I have hit a surprising snag: is it not possible to return the sequence of a selection through the interface? What I need to do is align fragments of sequence I have obtained from external annotations (RADAR in this case), with the SEQRES derived sequence to match the sequence numbers to each other - generally they are not the same. I think I could write FASTA to a file with "save" and process that, and I think I could capture the output of "info" and parse that through a function, but I am wondering if there is not a way to get the sequence directly as a return value? Thanks! Kind regards, Boris

VR on/off button
by Steffen Thomas 21 Nov '23

21 Nov '23

Hello I'm currently looking into the interesting possibilities of ChimeraX and VR. As I am in a different room to my PC with my glasses, I access the PC desktop via SteamVR with ChimeraX open and start vr on in the command line. This works quite well with a virtual keyboard from SteamVR. Now I'm missing two things so far, which I probably just haven't found yet (I'm a VR newbie even though I've owned a GearView for some time now, but its capabilities are quite limited). Firstly, a virtual keyboard where I can enter commands in the command line with the blue or yellow cylinders (I have now found the command line in vr) and a button in the toolbar (for example in the Molecule Display area) that switches vr on or off, in the same way for example as show and hide ribbon. Are there any possibilities to realize this via python itself? Or plans to integrate something like this? Many thanks to the great ChimeraX community and all those responsible.

measure rotation showAxis does not create a measurable object
by Alexis Rohou 20 Nov '23

20 Nov '23

Hello again, I have been using "measure rotation" to create several rotation axis objects, with the goal to measure angles between the various axes. Two of my axes are #4 and #5. When I try to measure the angle with "angle #4 #5", I get the error: "Must specify exactly 3 atoms/centroids or two measurable objects (e.g. axes/planes)" I notice also that the axes created by "measure rotation" do not show up in the "Structure Measurement" UI tool, which I guess is related. Would it be possible to please amend the output of the "measure rotation" command so that the axis (and slabs) it outputs are measurable? Cheers, Alexis
