Hi Elisabetta -

Following up from what Doug mentioned, if you're gonna subdivide the Insula, you may want to consider a function-based triplicate division: Dorsal Anterior Insula, Ventral Anterior Insula and Posterior Insula. I have attached an image that explains this.

Alan

We don't have post vs ant insula, but have you looked at the aparc.2009s.annot? It has a much finer insula segmentation. You might be able to merge some of those labels to get what you want. Otherwise, you can split the big insula label in the aparc with mris_divide_parcellation

Dear Freesurfer team,

I am looking for segmentation of the anterior versus posterior insula.

Does FreeSurfer provide that?

Many thanks,

regards,

Elisabetta

Hi Experts, 

I've finished my run of generating volumetric and Tracula data for subjects.  I was wondering if there is a way of displaying significant regions that correlate with clinical traits and also by groups. 

If there is a page describing this function, please help to share. I only find knowledge about group analysis. 

Thank you so much and I really appreciate it!

Best, 

Qi
