Dear FreeSurfer team,
I want to analyze regional cortical thickness using higher-order statistics implemented in an external C routine. This is currently done exporting thickness information in spherical coordinates for all subjects to ascii files for subsequent analysis (mris_convert -c lh.thickness lh.sphere lh.thickness-sphere.asc) After analysis I end up with one file for each subject having the same format as lh.thickness-sphere.asc but with thickness replaced by some higher-order statistics.
Is there an easy way of bringing back this information into FreeSurfer format for display with tksurfer? If not, what else would one do to display information on anatomical surfaces, given FreeSurfer's vertex identification number and a scalar quantity?
Thanks, Christian
