[Eeglablist] Plot study ERSP significantly different from baseline

[Makoto Miyakoshi]

Dear Nikola,

Sorry I did not understand the question very well. I thought that I would
compute statistics from the baseline period data and use the 1 percentile
value to threshold the after-baseline period for each frequency...
