Hi Ido, There may be features of which I am not aware, but the only way I know how to compute geodesic distance on a surface is through the Surface: ROI menu.
Select the Inflated surface, all nodes, Operation Selection: Geodesic distance. You can specify the source node by number or click it with your mouse. This will create metric and geodesic columns (probably identical, but differ in D/C options) of geodesic distance from the source node -- *to each node*. So you'll have to save this metric file as ASCII and look up the distance by node number. I don't know a more direct route, unfortunately.
