% 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.
