Hi Jeff,
they different parcellations based on different anatomical conventions. The
aparc.annot is simpler (fewer units) and gyral based, while the
aparc.a2005s has more units divided into sulci and gyri.
cheers,

Hello all,
Thank you for your quick replies to my previous posts. One more
question. I am wondering what the difference is and if I should be taking
average thickness measurements for cortical regions from
lh.aparc.a2005s.stats or lh.aparc.stats. I think the main difference is
that lh.aparc.a2005s.stats was made with ?h.atlas2005_simple.gcs and lh.aparc.stats was made with ?h.curvature.buckner40.filled.desikan_killiany.2007-06-20gcs. Which one is more accurate? I am using freesurfer 3.0.5.
Thank you,
Jeff Sadino
