custom topography for topoplotER

[Thomas Thesen]

Hi Robert, Eric & Others,

I am trying to use TOPOPLOTER to make topographic plots of averaged
waveforms with interpolation between electrode positions.

However, it seems that TOPOPLOTER uses a 2-D circular view of the head (with
nose & ears) as a a default plotting background structure. My data was
recorded from a 8x8 electrode grid (square and equal spacing). I made an
appropriate layout file (.lay), which works well with MULTIPLOTER, but not
with TOPOPLOTER.

Any suggestions on how to make this work would be greatly appreciated.

Cheers,

Thomas
