Hi all, I found answers to ponts 1 and 2 in the webpage. Sorry for my question....

Hi all,
I would need some information about the local gyrification index. I run the analyses and found which are the average indices for subject and hemisphere.
- Is there a method to perform vertex-wise group statistics? that is may
I compare maps of gyrification across groups?
- Is there a method to obtain average gyrification for a single label of
the atlas? For example gyrification of superior frontal gyrus. I understand that sulci are often used to find the delimitation of a gyrus or a brain area, and probably this is a problem.
- Are there any other method to measure the presence or the depth of a
sulcus. We are analysing a group of subjects with a genetic illness. They often lack a sulcus in the orbitofrontal area. Is there a method to quantify this using freesurfer?
thank you for your help
best wishes
Angela
