Thanks Bruce. I just checked the TkSurferGuide and noticed that it says the scale bar is 1mm (which looks about right). However, while the scale bar at the default zoom looks fine, I find that it's length behaves strangely (it shrinks) when I zoom into the image. Does the distance value change, or might there be something wrong with my display?

Hi Eric,
in tksurfer click view->scale bar to see the 1cm bar.

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?
