Please disregard and delete the previous message. I messed up and accidentally CC'd the chimera users list instead of the licensing address. Elaine ----- Elaine C.

Requesting protocol to find protein configuration units
by Panapakam, Jyotheeswaran 17 Aug '23

17 Aug '23

Dear Officail, This is Jyo writing from UNT biological sciences at Denton, TX, USA. I have been using your software for my research project for about an year. I was looking for a help/instructions about how to find out the configuration change in the protein after docking with a ligand. I have heard about RMSD docking value, that will be given in Amstrong units, could you kindly instruct me the process to perform it. It would be more glad if you are able to answer me withing a week from now : ) Sincerely, Jyotheeswaran Panapakam, PhD Candidate &Teaching Assistant, Department of Biological Sciences, University of North Texas.

Re: [chimerax-users] re error with Movie recorder utility
by Elaine Meng 16 Aug '23

16 Aug '23

Hi Anna, This chimerax-users email address is for questions about ChimeraX, but it sounds like you are using the Chimera program instead, since only Chimera has a Movie Recorder tool. So I am CC-ing the chimera-users email address on this reply, and you do not need to re-send your question. There is no separate "freeware version" -- Chimera is free for academic use and the download is the same for academically or commercially licensed users. (This is also the case for ChimeraX). The Command Line is always for entering one command at a time, i.e. that is the normal situation, not a problem or bug. If you have just a few commands you can enter them as one line with semicolons between them. However, if you mean that you have a script that contains many Chimera commands, you do not enter them one at a time into the command line. Instead you use some text-editing program (outside of Chimera) to create a plain text command file containing those commands, then you open that file using either the Chimera menu File... Open, or the Chimera "open" command. Normally command files are named with the filename extension ".com" or ".cmd" so that Chimera knows what kind of file you are trying to open. See Chimera help pages and tutorials on making movies, namely: Making movies: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/movies.html> Movie Recorder help page (you can just click the Help button on the tool, or see the copy of the same thing at our website here): <https://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/recorder/recorde…> Chimera movie-making tutorials: <https://www.rbvi.ucsf.edu/chimera/data/tutorials/movies09/moviemaking.html> <https://www.rbvi.ucsf.edu/chimera/data/tutorials/movies08/moviemaking.html> I hope this helps, Elaine ----- Elaine C.

making composite map using vop maximum command
by ytakagi＠iu.edu 10 Aug '23

10 Aug '23

Hi I want to make a composite map using two locally refined maps. I tried Phenix but did not work well. So, I like to do it by Chimera. Apparently, a composite map can be made using Chimera's vop maximum command. But I could not find the instruction of how to do it. Can you tell me how to do it? Thanks

Good morning! I have doubts about how to turn the peptide structures of the four images below (A), (B), (C), and (D) into a cartoon model like figure (E). I've tried, but I'm not succeeding.

Saving phi psi values to a text file
by Prathvi Singh 06 Aug '23

06 Aug '23

Hi Elaine, Is there a command to save the phi and psi angle values of each residue of a PDB file in a text file using UCSF chimera? I know we can do this in chimeraX using the command: save C:\myphi.defattr attrName phi format defattr model #1 Also, can we use chimeraX to save the phi and psi values in a single file? Thanks in advance -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016

Hi Elaine, I want to select all the atoms except the backbone oxygen and nitrogen atom of residues 100.A to 120.A . Is there a command to do this in either chimera or chimeraX? -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016

Here are the conditions: 1. There are two domains in each structure 2. I want to overlay the first domain and measure the rotation of the second domain 3. There are lots of structures, so I want to minimise the number of steps 4. I'd like to do this with a script and the --no_gui option on headless Chimera Here is my current script for the routine: open pdb1 open pdb2 match #1:1-50 #0:1-50 write format pdb relative #1 #0 t.pdb delete #1 open t.pdb match #1:55-80 #0:55-80 measure rotation #1 #0 delete #1 open pdb3 ... Is it possible to not have to write, delete, and open #1 after the first match step? If I don't do this, then the measure rotation #1 #0 will measure rotation of the initial match rather than the second match. Thanks for the help. Best wishes, Reza Reza Khayat, PhD Associate Professor City College of New York Department of Chemistry and Biochemistry New York, NY 10031
