¥ SUMA is the AFNI
surface mapper
H For displaying surface models of the cortex
² Surface models come from FreeSurfer
(MGH) or SureFit (Wash U)
H Can display functional activations mapped from 3D volumes to the
surface
H Can draw ROIs on the cortical surface
¥ SUMA is a separate program from AFNI, but can ÒtalkÓ to AFNI so that
volume and surface viewing are linked
H Click in AFNI or SUMA to change focus point, and the other program jumps to
that location at the same time
H Functional overlay in AFNI can be sent to SUMA for simultaneous
display
¥ And much more Ñ stayed tuned for the SUMA talks to come!
