Along these same lines, is it possible to overlay/display a Cartesian grid on the surface, a la the Neuroimage '99 II paper (Fig 7)? And is it possible to specify what the 'north pole' of this coordinate system is? For example, if I wanted it to be at the posterior end of the STS. I'm looking to do this on a flat patch. Thanks.

Hi Eric,

I was wondering if freesurfer has a way of generating a scale for distance, similar to what one would see in the legend of a roadmap. I'm thinking of using such a scale for a 3-d pial surface-render of an averaged brain (as generated using make_average_surface). Since it's a 3-d image, I had in mind a sort of 3D Cartesian coordinate scale, with scale bars for the x, y, and z directions. Does freesurfer have some visual representation of a distance scale like I've described, or perhaps some alternative?
