If I understand correctly, the surface-based morphometry (SBM) done by
Freesurfer offers superior registration as compared to voxel-based methods
such as VBM, in that:
1. "SBM smoothing respects anatomical boundaries better than the 3D VBM
smoothing".
2. "SBM group analysis employs inter-
Hi Tudor

kernel gets it only ever includes cortical gray matter. In contrast, volume
smoothing kernels will happily smooth in white matter, skull, csf, the bore
of the scanner, etc as the kernels get big.
