[Freesurfer] sub-parcellation

I just attended the pre-OHBM FSL/FS course, and spoke to David Salat there about possibilities to create more detailed sub-parcellationsfrom the two major structural atlases. Could someone please let me know if David was right that such tools exist, and/or point me to them?

My goal is essentially to create relatively equal-area parcellations with say 100, 200, 500, 1000, 2000, 5000, etc. ROIs per hemisphere, retaining some type of labeling to indicate where each ROI came from.

Thanks, -Jeff

PS I am at the HBM meeting through mid-day Thursday if someone here is able to talk to me in person (maybe even David!). My cell is 971-533-3942 if someone in Seattle wants to call or text.
