These images show (1) the unlabeled surface, (2) the aparc surface, and (3) the aparc.a2005s surface.

Hi, I think I may have observed the same issue he's talking about. What I've attached is possibly an extreme example (I haven't inspected many yet, to be honest), but it seems typical for at least a bit of this to happen in our subjects. I was also curious if the black "unknown" label was expected to extend into the temporal lobe as it does here.
Thanks,

Hi Greg,
Could you send along jpegs or rgbs detailing what excactly the parcellation atlas is doing in the cingulate region? Also have you looked at both the white and pial surfaces in this area?
Hope you are well othwerwise,
Rahul

Dear Karl,
Has anybody had any success with the midline rois given by the atlas curvature.buckner40.filled.desikan_killiany that is automatically applied by autorecon3 under the newest stable release, version 3.0?
Our trouble lies in the regions labeled corpuscallosum and <anything>cingulate: this atlas is giving us a corpus callosum that is exactly the ventral cingulate sulcus, and the 4 cingulate gyrus segments, which is what we are interested in in this case, incorrectly exclude their ventral portion.
