Hi Rick,
maybe a little bit of concern :) I havent worked with AFNI in a long time.
Specifying the file extension in the prefix does seem very reasonable, since it needs to know which format to save the data in.
I have one last question, if I may. The -no_images option disables @chauffeur_afni command. Is there a way to generate the QA images, but not automatically display them? I would think, that Xvfb is needed only to display the QA images remotely. Or is Xvfb an integral part of the chauffeur function?
Thanks!
Best wishes
Renat.
