AFNI -com option : BRIGHTNESS CHANGE

AFNI Message Board

I am trying to save images automatically by using this command :

afni -noplugins -no_detach
-com ‘SET_XHAIRS A.OFF’
-com ‘OPEN_WINDOW A.axialimage mont=9x9:1’
-com ‘OPEN_WINDOW A.coronalimage mont=9x9:1’
-com ‘OPEN_WINDOW A.sagittalimage mont=9x9:1’
-com ‘SWITCH_UNDERLAY A.img.nii’
-com ‘SAVE_JPEG A.sagittalimage ./check_sag blowup=3’
-com ‘SAVE_JPEG A.axialimage ./check_axi blowup=3’
-com ‘SAVE_JPEG A.coronalimage ./check_cor blowup=3’
-com ‘QUIT’ \

How can I change ‘Brightness’ for this?

Hi, Jung-

I don’t know what “brightness” means.

And have you looked at the @chauffeur_afni command? It has a looooot of options to use for generating/saving images:

Here are a looot of examples online:

Regarding the brightness, if you are referring to how the underlay dataset is scaled to the grayscale, see this very old post.
