¥Without creating
individualized surfaces, you can display data on a Talairach-ed surface model.
HThe surface models were created with FreeSurfer from the
N27 data set. (Holmes, CJ et al. JCAT 1998)
HAnatomical volume and surfaces were Talairach-ed using
AFNI and SUMA, respectively. (Surfaces created by Brenna
Argall)
¥Demo: (close previous SUMA and AFNI
sessions)

åYou should find Anat+tlrc and a functional data set in Talairach space
