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!
