Question about save images
by Chang, Jufang 29 Apr '24

29 Apr '24

Hi, there, I used Chimera for a very short period of time. When I just started using Chimera I was able to save image by going to "file" and "save image" to save the image on the display window. For some reason, this stopped working. Now, after I did the same thing, the image I saved has complete blackness (attached). I wonder whether I might get be able to get help from you. I also tried using command line to save image. The result is the same. The exact procedure I used are: Go to "Presets", choose "publication 1" , then go to "File" and "save image" I used window system.

Unable to run UCSF chimera using
by Prathvi Singh 30 Aug '23

30 Aug '23

Hi, Is it possible to use python to execute commands on the command line of UCSF chimera without actually opening its GUI on the Windows platform? If not, then how to use python to open its GUI and execute the commands? I tried the "subprocess.Popen()" and "os.system()" methods to run its GUI by passing the path of chimera executable (version 1.17.1) to them but chimera is displaying an error with exit code 1 (snapshot attached). However, I am able to launch chimeraX (version 1.6.1) via these methods. -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016

Hi all, I wish to use Chimera for my students to view organic models that I created in MOE. How can Chimera display double/triple bonds? They appear as single bonds in .pdb, .mol, .mol2 formats. Thanks.

How to show certain hydrogen bonds and hide others
by Karjalainen, Mikael 29 Aug '23

29 Aug '23

Hi! I am having problems to show certain hydrogen bonds and hide others. For example, I would like to hide some completely. Then others should be shown always. Even when atoms are not shown and only ribbon is. I couldn't find how to do this by googling or for example reading how to use hbonds command. I am using Chimera 1.16. I know that there is ChimeraX, but now I need to modify old project. Regards, Mikael

Atlocs

Dear ChimeraX, I have an atomic model with several chains that have residues with alternate locations A and B. I noticed that while Chimera by default displays alternate locations A. ChimeraX for some chains display alternate locations A and for other chains alternate locations B. Why is this behavior different in Chimera and ChimeraX? Is this a novel feature of ChimeraX? I this is the case how ChimeraX decides which of the two alternate locations A or B to display? Thanks Hernando ___________________________________ Hernando Sosa, PhD.

Moving atoms of a protein
by Abril Gijsbers 18 Aug '23

18 Aug '23

Hi Elaine, I have this alphafold structure (see picture) that is basically a huge string/thread and then a folded domain. I wanted to stretch the string to make its length more obvious. Is it possible to pull the residues without messing with the connections (peptide bond)? I am using chimeraX and I saw that you can "move atoms" but when you pull one you don't pull the others. If chimera cannot do this, do you know if another program will allow me to do it? Thank you in advance for your help, Best regards, Abril Gijsbers [image: image.png]
