On a side note, we don't recommend using volumetric methods for group cortical analysis, volumetric cross-subject cortical alignment isn't as good as mapping to surface and using surface registration, because volume registration doesn't deal with cortical folding variability well (and also because function varies in its placement relative to folding patterns). See our recent paper for details:
