Andy - If you mean topoplot(), then there are keywords to control how much of the 'skirt' outside the head is plotted, etc. (I tried to interpolate only within the convex hull of the electrode positions, but could not get it to work consistently -- anybody wanting to try this, it would be of value, I think).<div>

The problem is that the figure it produces interpolates outside the channels I give it.
