You then may loop over components and save or plot.Hope this helps!

In other words, what I want is a channel ERP with one line for each component ERP at that channel instead of one "average" line. I thought of removing all ICs but one from a dataset, plotting the backprojected channels, then removing all ICs except another IC and add its backprojected ERP to the channel plot constructed before and so on. This would probably work but it is a bit hacky and slow. Are there maybe a few lines that could be removed/commented from some functions or something? Or is there even an existing function that I missed?> > Best> Ingmar> _______________________________________________> Eeglablist page: http://sccn.ucsd.edu/eeglab/eeglabmail.html> To unsubscribe, send an empty email to eeglablist-unsubscribe at sccn.ucsd.edu> For digest mode, send an email with the subject "set digest mime" to eeglablist-request at sccn.ucsd.edu
