to decide.

Hi,
I have an area of significance on the mesial surface of the hemisphere
(please see attached tiffs). I would like to know if it is exclusively in
the cingulate or in cingulate and SFG. The prolbem is that the two atlases
don't agree. The upper more than half of this significant area is in SFG
according to lh.aparc.annot and in cingulate gyrus and sulcus according to
lh.aparc.a2005s.annot.
I know there have been some issues before with cingulate and SFG in the
Destrieux atals (
http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg05399.html)
but it's unlcear to me whether these have been resolved. As you can see from
the tiffs, in lh.aparc.annot the significant area is inside the corpus
callosum (a small part), caudal and rostral ant. cingulate, and SFG. In
lh.aparc.a2005s.annot it is inside pericallosal sulcus, g. cingulate main
part, s. cingulate main part, and only a very small part of it extends into
SFG.
These are substantially different interpretations. Is one atlas more
accurate in this region?
Thank you!
