Good morning,
I am working with NODDI data and have created surface overlays in FreeSurfer space with NODDI values. I am interested in calculating vertex-wise asymmetry indexes utilizing fsaverage_sym similar to Greve et al Journal of Cognitive Neuroscience 25:9, pp. 1477–1492. I would ultimately like to extract average AIs for an ROI analysis. My question is how do I extract the overlay stats from the surface overlay mgh file to obtain average AI in each ROI?
Thanks! Jim Gugger
