Hi Wing, Clicking the icon that looks like a camera executes a ChimeraX command something like

save ~/Desktop/image1.png supersample 3

...as described in https://rbvi.ucsf.edu/chimerax/docs/user/tools/toolbar.html#home

In your case it doesn't work because you don't have permission to create files in that folder.

For now, you would need to use the "save" command in the command line and instead of ~/Desktop/image1.png you would put some location in which you are allowed to create files. You can name the file what you want, except it should end in some image format suffix like .png. For example, if there is already a folder C:\My Files\ where you have permission to add new files, then the ChimeraX command could be something like

save C:\My Files\somefilename.png

Sorry, I don't know much about the folders on Windows, so you will need to figure out what location is possible on your own computer and put it in the command.

I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco
