- % SPM canonical meshes
- %__________________________________________________________________________
- %
- % The cortical mesh surfaces here were created using Freesurfer version
- % 4.0.1 (Dale et al. 1999, Fischl et al. 2001, Fischl et al. 1999) from
- % an average of 27 T1 scans of the same subject (see spm_templates.man and
- % Tzourio-Mazoyer et al. 2002 for more details).
- % The surfaces were inflated to a sphere and down-sampled using an
- % octahedron (8,196 vertices) or an icosahedron (5,124 and 20,464 vertices)
- % equally subdivided to achieve the highly tessellated surfaces provided.
- %
- % The boundary element model surfaces were created using the watershed
- % algorithm (Segonne et al. 2004). These surfaces were created
- % utilizing an icosahedron equally subdivided to create a highly
- % tessellated surface. Some manual editing was applied to the T1 images
- % in order to optimize the performance of the watershed algorithm.
- %
- % The meshes were subsequenlty warped using the deformation field created
- % by the new segmentaton algorithm, so that the reference space was defined
- % by spm12/tpm/TPM.nii, to improve the accuracy of the alignment.
- %
- % They are saved in the GIfTI file format, with GZipBase64Binary encoding.
