[Eeglablist] How to Produce Spline interpolated isovoltage maps with EEGLAB

[Makoto Miyakoshi]

I believe there is 'contour' option in spectopo() function. I got an
inquiry from my old friend and collaborator if there is any optional
command to control the low-level behavior of this option (which I could not
find).
