Feature of chimera
by Arpita Nandy 19 Aug '24

19 Aug '24

Hi, I am a PhD student from Germany and would like to make a figure where I can highlight specific proteins of interest in the mitoribosome complex of yeast. Could you please assist me to use ChimeraX in this context. Best regards Arpita Nandy

Usage and Distribution of ChimeraX at our Upcoming Max Planck Institute Summer School
by SantaLucia, Daniel 15 Aug '24

15 Aug '24

Hello ChimeraX team, My name is Dan SantaLucia; I'm a research scientist working under Prof. Frank Neese and Prof. Serena DeBeer at the Max Planck Institute for Chemical Energy Conversion. One thing we do every year is to organize a summer school for students from all over the world, where they get to learn in-depth about many different spectroscopic techniques as well as quantum chemical calculations to help them in their interpretations of these datasets. You can find more information here, if you're curious: https://summerschool.cec.mpg.de/en/home thing that would be really nice would be to offer students the ability to use ChimeraX alongside our tutorial/practical sessions. We use ORCA to do calculations (considering, of course, that Frank invented it), and we've found that ChimeraX has a lot of really nice features that would be perfect for helping the students to learn. What I wanted to ask was this: do we have permission to distribute the download files at: https://www.rbvi.ucsf.edu/chimerax/download.html to the students? They would be distributed on flash drives that we give to the students, and we would distribute the Windows, Mac, and Linux versions so that we could cover all users. The internet connection is not the best, unfortunately, at our venue, which is why they can't just go to the link to download it themselves. To be clear: this is a non-commercial use event, where we simply have international students coming to attend the summer school, and this is an event that is for learning purposes only. Nonetheless, I want to have your explicit permission for distribution of ChimeraX to the students as well as your permission for them to use your software at our summer school? Thanks so much, and looking forward to hearing back from you, -Dan [1668779311055] [1668779979115] Dr. Daniel J.

problem to open a swiss dock results file
by Aurélie Hoeffel 13 Aug '24

13 Aug '24

Dear Chimeras members, I would be interested to use chimera x for interpreting some results of my docking. I precise it is the first time I use swiss dock as well as chimera x, after receiving the swiss dock file in a tar.gz format, I compress it via 7Zip but then chimera x, is not able to process and open my document, ii is just written, tar data ,Unrecognized file suffix '.tar', so I do not kwo if the pb come from chimera or swiss dock, do you know how I can solve the problem? Thanks in advance, Aurelie

ChimeraX-daily (1.9, 5 Aug 2024); Log panel stealing focus
by leeyang+chimerax＠gmail.com 10 Aug '24

10 Aug '24

Hi, Downloaded the above Daily (macOS 14.5, Universal), primarily for the workaround retrieving mmCIFs containing an underscore (#15557). I noticed that the Log toolpanel steals focus whenever it updates. Perhaps something that has already been dealt with? Otherwise, thought I should post it here. Cheers, Yang

Could not display the lipid such as cardiolipin
by 杨雪梅 08 Aug '24

08 Aug '24

Dear ChimeraX support group, When I open my PDB with ChimeraX, some lipids (get from the coot library with three-code) could not be seen. When it open with pymol, the lipids were displayed normal. Have you met such problem and how did you fix it? Looking forward to your kind help. Sincerely yours, Xuemei Yang Chinese Academy of Sciences Shanghai Institute of Materia Medica

problem for the PDB deposition
by Yanhe Zhao 07 Aug '24

07 Aug '24

Dear ChimeraX community and developer, I am trying to deposit my map with model. I save the model from pdb to cif in ChimeraX because of large amount of atoms, then got error as "Missing '_entity_poly.pdbx_strand_id' item. I tired to use pymol to open my pdb and save it as cif by 'Export Molecule', in which I just use the default options. I checked the saved cif in ChimeraX, which is weird since it couldn't be show in cartoon style. Is there any easy to handle this in ChimeraX or any option should be used in the 'Export Molecule' in Pymol? Thanks and cheers, Yanhe

Inverted fit in map ?
by GOVAERTS Cédric 07 Aug '24

07 Aug '24

Hi Team I would like to compare to conformations of a protein whose structures have been solved by cryoEM (conf1 with map1 and conf2 with map2) So I want to have the coordinates *and* the cryoEM maps aligned. Aligning the two conformations is easy thanks to matchmaker (align conf1 to conf2) However, I can I align map2 onto conf2 so that I can compare with map1 ? Basically I would like to do an “inverse” fit into map conf2->map2. Can I do that ? Note : I do not want to align map2 ontomap1 because of resolution and structural differences, the superimposition should be done at the coordinate level (actually on a subset of it which is easy in matchmaker). Thanks ! Prof. Cedric Govaerts, Ph.D. Universite Libre de Bruxelles Campus Plaine.

Question regarding per-Residue RMSD
by Zimiao Meng 07 Aug '24

07 Aug '24

Dear Developers/Researchers of ChimeraX, I'm a student researcher trying to utilize ChimeraX to analyze structures of models predicted by programs. Currently, when I do matchmaker, only the RMSD value is displayed. I'd like to know the per-residue RMSD (which should also be the alignment error for that residue) for a section of the sequence that's a few hundred residues long. I wonder if there is a way to display the information that ChimeraX used to calculate the overall RMSD? Or would the only way to do it be writing a python script? Best, Zimiao
