[Eeglablist] exporting laplacian values from del2map

I am trying to run t-tests on Laplacians between two ERPs at one time
point. I obtained laplacian maps using del2map and topoplot, but could
not find a way to export the computed laplacian values for each

My data contains 81 channels (interpolated), but sumLaplac2D in
del2map.m gives 67 by 67 matrix output. Is there a way to figure out
which values in this matrix corresponds to each channel?

I tried to use noplot option in topoplot.m, by writing "noplot =
[radvalue thetavalue]", the topoplot output was still 67 by 67 matrix.

Thank you,
