We don't have an anterior insula segmentation. One thin you can try is to divide the insula label with mris_divide_parcellation. If one of those subdivisions works for you then you can compute the thickness inside it. You might want to do it on fsaverage and then map it back to the individual subjects. Or you can just draw the label you want on fsaverage and map it back to the individual subjects

Dear freesurfer experts,

I have a question regarding analysis of cortical thickness.

In the stats folder of each subject, the {hemi}.aparc.stats file gives the thickness of several areas, one of them being the insula. Is it possible to get only the anterior insula thickness?

Thank you in advance, and I hope to hear from you soon.

Best,

Hanne van der Heijden
