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?
It should do the same thing
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?
I've not used this, so I don't know how it would work. You can run mri_sclimbic_seg to get an actual fornix segmentation
(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.
I think it just divides it up in to more-or-less equal sized segments.
