[Eeglablist] ica weights

[Marta Zakrzewska]

If you want to plot the timecourse of your components' signal you can use
eegplot
>> eegplot(EEG.icaact, 'srate', EEG.srate)

Note that you need to compute the icaact matrix first though - you can do
it using eeg_getdataact function:
>> EEG.icaact = eeg_getdatact(EEG,'component', 1:size(EEG.icaweights, 1));

Hope it helps!
