[Freesurfer] the thickness of manually selected vertex

Hi, there,

I have two questions about the ?h.thickness file.

If I load a subject's surface ?h.inflated using tksurfer, then I load its thickness file ?h.thickness,

By clicking mouse on the surface, I can read the corresponding curvature value of a specific vertex.

Q1, Here, the value next to 'Curvature' is actually its thickness value, right? Q2, If I select four vertexes on the surface, is there a way that I can save the thickness values of these four vertexes into a txt file?

Thanks! Guang _________________________________________________________________ Hotmail is redefining busy with tools for the New Busy. Get more from your inbox. http://www.windowslive.com/campaign/thenewbusy?ocid=PID27925::T:WLMTAGL:ON:W...
