Hi Mike, I can't remember all the details (and the guy who wrote it is
gone), but I remember that it was not all that sophisticated (though it
works pretty well). I think it choses the next vertex based which one
will get it closer in 3D space (and not retrace it's steps). I think it
uses whatever surface you're drawing on.

Hello,
I was wondering what approach is used to connect marked vertices when
using the "Make Path" and "Make Closed Path" tools of tksurfer.
Does the "connecting" operation just use the shortest (geodesic)
distance between vertices, as determined by the currently displayed
surface?
Does the 'mri_path2label' binary use the same algorithm?
And, is there any mechanism for taking curvature or sulcal depth into
account? (e.g., connect points along a line of minimum or maximum
curvature change, rather than using geodesic distance)
thanks,
Mike H.
