  Hi Daniel

you could do this in tksurfer, but I don't think there is a commandline facility for it (although you could write a matlab script to do so). In tksurfer, I would:

1. Load the label.
2. Copy label statistics to overlay
3. Delete the label
4. Load the parcellation you want to use
5. Use the custom fill with "up to functional threshold" and "up to

different labels" check (not sure of the exact wording). 6. Left click in a region that you want, and click fill. 7. Save the label. 8. Right click to unselect and go to 6 until you are done with all the subregions

cheers Bruce

  Dear FreeSurfer Experts,

If I have a label that spans across multiple anatomical regions, is it possible to automatically break it down according to aparc.annot? Thanks! Daniel --  Yung-Jui "Daniel" Yang, PhD Postdoctoral Researcher Yale Child Study Center New Haven, CT (203) 737-5454
