Notes

Atlas from (Craddock et al.[1]).

Collection of regions of interest (ROI) that have been generated from applying spatially constrained clustering on resting-state data.

Several clustering statistics are used to compare methodological trade-offs as well as determine an adequate number of clusters. The proposed functional and random parcellations perform equivalently for most of the metrics evaluated. The online release also contains the scripts to derive these ROI atlases by using spatially constrained Ncut spectral clustering.
