Hi Nicholas
mri_vol2surf has options that lets you control its behavior. It can do various types of sampling (e.g. averaging within the cortical ribbon, point sampling at a specified distance or percentage, etc....)

I looked over the documentation but can;t seem to find what I am looking for. How exactly does the function project the mdi data onto the surface? What method is it using to accomplish this, is it just projecting to the nearest neighbor or is there something more complex occurring. I ask because I just want to make sure I completely understand what every step in my analysis is doing and not have it be a blackbox that I put data in and it gives me stuff out. Thanks for your help. Nicholas
