[Freesurfer] automated parcellation

Dear Freesurfers,

We have used the automated parcellation (Fischl et al, 2004) in several subjects and noticed in some cases labeling of the lateral part of a gyrus (i mean the part that's visible on the folded surface), as belonging to a sulcus. The example I have in mind is the labeling of a gyrus that could be the middle temporal or the angular gyrus as the posterior part of the superior temporal sulcus (STS). I figured the program could not find the correspondence between that particular gyrus and any labels and, since it happened to be close and, sometimes, between two branches of STS, it was labeled as such.

Or we made a mistake somewhere ... ?

Could anyone please comment on this ?

thanks !
