R Insula results from the rCBP procedure. a Insula parcels for the two-, three-, four-, and five-cluster solutions obtained from rsfMRI (top row) and dMRI (bottom row) connectivity. All images are in the same view (right-sided) as Fig. 2b. b Internal validity scores for all tested solutions ($k=[2,3,4,5]$). The Silhouette index (left) and the Calinski–Harabasz index (right) indicate a better fit through a higher score, whereas the Davies–Bouldin index (middle) is better when lower
