[Eeglablist] averaging across channels

[Arnaud Delorme]

Dear Olga,

you have to write a script to average channels. For instance to plot the 
ERP of the frontal channels of the current dataset:

1- find channel indices for your frontal channels, say [1 3 5 9 10]

2- type in on the command line

figure; plot(EEG.times, mean(mean(EEG.data([1 3 5 9 10],:,:),3),1));
