Hello, CCing chimera-users(a)cgl.ucsf.edu (recommended address for questions to ensure it doesn't fall through the cracks... and also because often other people know the answer when I do not)... <https://www.rbvi.ucsf.edu/chimera/docs/feedback.html> I guess you are talking about method "b" in that post? I believe the values would also go to the Reply Log in addition to the status line. You can save the Reply Log contents using a bit of python. That is beyond my expertise personally, but fortunately is described at the bottom of this page on basic scripting: <https://www.rbvi.ucsf.edu/chimera/current/docs/ProgrammersGuide/basicPrimer…> I hope this helps, Elaine ----- Elaine C.

Help for USCF chimera
by cindy g 10 Mar '22

10 Mar '22

Good morning, By Uscf chimera I have a complex with an antibody and an antigen. After determining the predicted paratopes and highlighting only their side chains, I would like to identify the side chains of the amino acids of the antigen which are in a zone <5A from the side chains of the predicted paratopes. I don't know how to do it with command lines or anything. Thank you in advance for your help Cordially

Information Regarding Accessibility of Chimera
by Scott Heck 09 Mar '22

09 Mar '22

Good morning, I am a member of the IT staff for the Biotechnology department at NCSU, and we are wanting to install and use Chimera for one of our instructors to use in their classes. Prior to student use, I will need to have the software approved by the university, and they require proof of the software being accessible to all students. They specifically ask this in the form of VPAT, WCAG 2.0 Standards or other accessibility documentation. Any assistance you can provide would be greatly appreciated.

Changing distance between two atoms
by Prathvi Singh 04 Mar '22

04 Mar '22

Hi Elaine, I have a PDB file which has two serine residues: SER10.A and SER20.A. The distance between their sidechain O-atoms (OG atoms) is 8.925Å. I want to bring the sidechain O-atom of SER10.A closer to the sidechain O-atom of SER20.A along an imaginary line which passes through the coordinates of these two atoms such that the distance between them gets reduced to 4Å. If I am thinking right, this would also require shifting the rest of the atoms of SER10.A towards SER 20.A in a similar manner. Is it possible to achieve this in chimera? I am attaching a screenshot just for reference. Thanks anyways and regards -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016

I have a "residue" KCX (PDB records are Hetatm). In the sequence alignment it comes as X. Is there a way to change it to K without making a PDB file and changing it to K there? Thank you,. Jackie Vitali Cleveland State University

Average distance between two non-bonded atoms
by Francesco Pietra 24 Feb '22

24 Feb '22

Hi all Is it any command to measure the average distance between two non bonded atoms all over a molecular dynamics trajectory? Ideally linked to examining the trajectory with Tools ... MD/Ensemble Analysis ... MDmovie (I am using psf/dcd) I.e., doing the average of the distance from all frames. Thanks francesco pietra
