Hi,
In response to Christophe's question, I looked at the two other whole
brain parcellation schemes -- DKTatlas40 and a2009s. In those two
subjects at least, that me

I'm not itching to re-process this data so I like that explanation as

of medial tissue labelled as insula, whereas others don't. (Even within

Yeah, it is labelled as "Cerebral-cortex" in the aseg.mgz, and is just
medial to the "Accumbens" label.

Yeah, the insula label is present medially when viewed on the white
surface as well, so its not just a quirk of the inflation.
Not sure if I follow what you mean by the "aseg looking right". The

Hi Mike
I'm not sure - I think the insula was an additional label that Ron Killiany
