Dear Douglas,
I do not understand what's your meaning? Yes I think the afni results has already alined to T1.mgz, so it is already in talairach space. I do not know what to do next? As I have two groups subjects. I do not know what to analysis the correlation different between two groups by using surface-based analysis of freesurfer.

Are the AFNI results already in talairach space? If so, then there is no
point in going to surface space.
