quantifying surface area

2002-06-07 Thread Tom Schoenemann
Is there any way to get a measure of absolute surface area of, e.g., the pial surface of an individual? If so, can this be run on cut portions of the cortical surface (e.g., the occipical pole)? We worked our way to the point at which freesurfer has created a model of the surface of each

Hi Tom, we write out an ?h.area file that contains the area of every vertex in the tessellation (the average area of all triangles it is a member of). You should be able to convert it to ascii using mris_convert in the usual way. Also, note that the vertex index is invariant across the
