[Chimera-users] Virus Images for the MSD Database

Unfortunately Chimera is not able to save images without displaying
the graphical user interface. The image saving code grabs the image
directly from the main window OpenGL graphics buffer, so it also will
not work if the main window is covered or iconified. Greg Couch once
made a special version of Chimera for Linux using the OSMesa graphics
library that could do all the graphics off-screen including saving
images. But I don't see that version in the Chimera download archive,
and I believe it was made more than a year ago. We recently added
raytraced image capture using POVray. Since that does not use the
OpenGL graphics it should be able to work in nogui mode but a Chimera
bug report indicates that does not work
and is expected to be difficult to fix. Unfortunately the only option
at this time is to have the Chimera window appear to save an image.
