Hi Holger You should read the spherical warping and parcellation papers. The secret is not using landmarks but instead using the entire folding pattern Cheers Bruce

Dear Bruce et al.,
Submitting a paper in which I use freesurfer for the analysis of the auditory cortex, I was asked how freesurfer actually takes individual boundaries (e.g. of Heschl's gyrus) into account? Both atlases (Desikan and Destrieux) are based on about 10-20 subjects. How are these boundaries transferred to other subjects? As far as I understood the description of freesurfer there aren't any templates (or some kind of masks) which are put on the subjects to analyse. What's the "secret" or principle behind the individual analysis to receive reliable data for every ROI of every subject (in a nutshell)?
Thanks in advance, best wishes,
