Hi Yunus

The ones with “pial” in them are from the pial surface for things like curvature and surface area, the ones without are from the white surface. The rest of the name indicates which cortical parcellation the statistics are summarized in (e.g. the lh.aparc.pial.stats contains statistics for each of the parcels in the lh.aparc.annot computed using the geometry of the pial surface).

And Happy New Year to all!

Cheers Bruce

External Email - Use Caution hi freesurfers, I wanted to know what is the difference between '.aparc.a2009s.stats', '.aparc.DKTatlas.stats', '.aparc.pial.stats', and '.aparc.stats' in the stats directory of freesurfer results? thanks, Yunus
