It is hard to say without the data. I checked one of our cases and they
are different, although it was not from v6 (but I would not expect this
to change). Can you try running it in a newer version? Or re-run in v6?

Dear FreeSurfer developers and community,
I was reviewing the stats outputs of recon-all from multiple cases
processed using FreeSurfer version 6.0.0, and I encountered an unusual
issue. Unfortunately, I do not have access to the stats files, but
based on the results provided in excel, I have noticed that the gray
matter volumes for the caudal anterior cingulate and isthmus cingulate
are identical within each hemisphere. (lh.caudal_anterior_cingulate =
lh.isthmus_cingulate
rh.caudal_anterior_cingulate = rh.isthmus_cingulate). Also, the white
matter volumes for the isthmus cingulate are also identical between
hemispheres (lh.isthmus_cingulate = rh.isthmus_cingulate).
The consistent pattern across all cases and its limitation to the
cingulate regions leads me to question whether this could be possible
from an issue in the segmentation and parcellation processing, or if
it might be due to errors during data transfer.
I would appreciate your guidance. Please let me know if additional
details or context would help clarify this matter.
Thanks!
