Hello experts.

I have some question to you.

I used SurfStat statistical tool to analyze the two group(control, patient)

When i click the surf in fsaverage folder and then show up lh.pial and lh.pial_avg.

What is the differences between lh.pial and lh.pial_avg ?

lh.pial_avg means that real subjects's average pial?

plz reply.
