Hello Freesurfer team and thank you for your continued responses to questions. My questions pertain to mri_cc, and subsegmentation of the corpus callosum. In prior runs of version 6.0, it seems that aseg outputs the subregions of the corpus callosum. The option for mri_cc also identifies those segments, and (Question 1) I wondered if in version 7.4 how that differs from what aseg normally outputs? In addition, (Question 2) with the -f flag to include the fornix, does this mean that the fornix is incorporated into the five subvolumes, or is the fornix volume calculated separately? (Question 3), For the option to set a different number of segmentations, how does that translate into the five ‘default’ segments (e.g. Anterior, Mid-Anterior, Central, Mid-Posterior, Posterior). Again, thank you for the team’s continued work.
