.lay layout file for neuromag 306 channels

[Ingrid Nieuwenhuis]

Hi Sameer,

I might be able to help, but could you specify a bit more what you did? So
which topoplot did you call, and what was your cfg? And what are the fields
in your data that you want to plot?

Best,
Ingrid

Thanks Dasha for the files, though I learned from Christaian's email and
further studying createlayout that if the appropriate layout files do not
exist, createlayout can be used to create them.

But now I am getting an error which I dont understand.

topoplot([], lay.prj(1:307,1), lay.prj(1:307,2), compRR_orig.topo(:,1))
??? Error using ==> topoplot
Flag arguments must be strings


While trying to understand this error, I realized that in the topoplot.m
file

 	function [handle] = topoplot(varargin)

handle is never assigned a value....


best,
sameer
