Thanks very much for sending the script! I tried it and had a problem,
though.
Basically, when I try to plot, the script creates x- and y- axes but then
tries to plot the event-related responses in a different window.
Needless to say, I can't make anything out. Also, it seemed to take
about 2 hours to create the plot, which seems long relative to other
plots. Is that normal?
Any advice would be much appreciated (as always),
