Hi Pedro,

the mapping from tal to surface isn't well defined as there will be many tal coords that are not on the surface. You could find the closest point on the surface to a given coord, but many coords will have the same closest point

cheers, Bruce

In the attached figure:

The numbers (-28.25, -12.73, -0.57) refer to fsaverage. How can I export the Thickness values of the subjects for this cordinates?

The numbers (-28.25, -12.73, -0.57) are in Talairach space?

Thanks,
