Hello, The Release Notes of v4.0.0 indicate that one of the bug fixes was "Corrected midline parcellation". Is this a fix that affects the volume segmentation (aseg) or the surface parcellation (aparc)?
Is that the fix for what was described in the "Known Issues" of v3.0.5 as "During cortical parcellation, areas of the anterior cingulate cortex (rostral anterior cingulate in the parcellation atlas), are mislabelled as corpus callosum or "unlabelled subcortical". A fix for this is in the works, possibly for the next release."
thanks, Mike H.
