Dear Dr Fischl: I have seen in the paper "High-Resolution Intersubject Averaging and a Coordinate System for the Cortical Surface", in fig1, fig2, the subject image registered with the average folding pattern is much thick in both the sulci and the gyri, while the result in the bert tutorial is very thin(see freesurferguide.pdf page 48) Is the average folding pattern used to do the spherical registration different? How to make the less variable pattern image after registration?
