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. doug

My question is :1 Should I need to do mri_vol2vol next for each subject? 2 I have two group of subjects. I want to know if there is some correlation different between them? What should I do next? Thanks very much! Linda
Surface-based analysis is an alternative to talairach-based analysis. It does not make sense to do both. Is the AFNI talairach space affine (ie, 12 dof)? If so, then it is possible to undo the resampling to talairach space. You will need to know which space the afni results are in (ie, MNI152 or MNI305 or something else? 1mm or 2mm?) doug
