mris_curvature -max -w <path>/lh.white will write out the max curvature at each vertex to a file named lh.white.max. Load this into tksurfer as a using the file->load curvature menu.
You can then create a path in tksurfer by clicking on two end points, and type plot_curv 0 at the tcl (%) prompt. This will create a file named surfer_curv.dat, which has one row/vertex in the path with each column being: vno x y z distance curv val val2 stat amp the "curv" field will give you the max curvature at each point cheers Bruce On Fri, 4 Mar 2011, Allie Rosen wrote: > Hi Bruce, > > I managed to draw and save a curve over my area of interest.
