Hello, everybody.

In 2004 FreeSurfer course lecture slides by D Salat, B Fischl and D Greve there are a couple

of slides I am curious about. These are slides # 65 and #66 named correspondingly

“Thickness maps” and “Thinning from young to old age”.

Have those images been produced by FreeSurfer or some other tool? If it is images from

FreeSurfer, how do I get them?

Is there a way to do some group comparison or averaging with *.thickness surface files?

And displaying it afterwards?

Thank you.

Regards,

Renat.
