Colin27 high resolution cortical surfaces

This data set includes high-resolution (0.5mm) maps of the cerebral
cortical surfaces reconstructed from the Colin27 brain atlas
[Aubert-Brohe et al., 2006]. The tissue segmentation provided with the
atlas was manually edited to merge sub-cortical structures and lateral
ventricles with the white matter (WM), then the WM mask was
topology-corrected [Bazin et al., 2007] and the WM and cortical gray
matter (GM) masks were used to estimate cortical surfaces with the
CRUISE algorithm [Han et al., 2004] for the GM/WM boundary (gwb), CSF/GM
boundary (cgb), and an average surface (avg) equidistant to both
cortical boundaries. Surfaces were reconstructed as levet sets of a
signed distance function, and triangular meshes were extracted with the
connectivity consistent marching cubes algorithm [Han et al., 2003] and
inflated to obtain smooth cortical maps [Tosun et al., 2004].

Included
here are the left and right cortical segmentations (1=GM, 2=WM), level
set surfaces (gwb, cgb, avg) in compressed NIFTI format, and the
corresponding extracted and inflated (inf) meshes in VTK ascii format.
The NIFTI images are co-aligned with the Colin27 atlas in voxel space,
and the surfaces follow the MIPAV mesh space conventions.
