I have a question about using labels from different annots. The Desikan annot has a large region labeled unknown including medial wall and lateral insula and operculum. The Destrieux annot has a separate medial wall label. Is there an easy way to use the Destrieux annot label of the medial wall to subdivide the Desikan unknown label? Just trying to think of some way to do this without dividing the unknown label by hand for each subject. Thanks in advance.

Cheers,
