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.

Hello, We are using MECM (SCCM) to install Chimera and need to suppress ALL windows. I have tried the /verysilent flag but a command prompt still pops up with what looks to be the compiling portion. Is there a way to have ALL windows silent? -- *Jim Richard* Pronouns: he/him/his Client Systems Administrator

How do I colour all my hydrogen atoms grey?
by Mazin Nasralla 17 Jul '23

17 Jul '23

Hello, I imported an x,y,z model of water molecules into Chimera. I want to create an image of my water structure so I am setting the background to grey. That works. But I would prefer to set the hydrogen atom colour to light grey. I can't work out how to do that. I can select each individual atom, and then colour edit it but that will take ages. Is there a simple command line solution? Thanks Mazin

Chimera-X inteprhase of the AlphaFold
by Enrico Martinez 13 Jul '23

13 Jul '23

Dear Chimera-X users! In parallel to the modeller, I am trying to use the Alpha fold interface with the aim to full model starting from the sequence using template. The problem is that I can not define manually which template I would like to use for each prediction so the interphase takes its automatically based on the input sequence and the final prediction is not very precise. Would it be possible rather to specify a specific pdb ID additionally to a given sequence ? Many thanks in advance Enrico
