Anqi,

The default surface file generated by freesurfer is a proprietary format, but the freesurfer utility 'mris_convert' will convert to ascii and vtk formats (among others). Two examples:

mris_convert rh.pial rh.pial.asc

creates an ascii file of triangle vertices and faces, and:

mris_convert rh.pial rh.pial.vtk

creates a vtk formated file. See:

mris_convert --help

and also:

Coords are in subject space (not talairach space, but a mris_convert allows specify a transform file).

Hi, Could you let me know the format of the surface generated by freesurfer? Is that easy to convert it to *.vtk? And also is the surface in the original subject space or in Talairach space? Thanks
