Dear Bastien,

If you want to report multiple significant points on your ERP (I guess) you
need to report bunch of statistical scores... that will make another line
plot. To obtain the statistical values for each points, you have to access
values under STUDY.cluster(x).icaerp (don't forget that you plot all
cluster ERP first, close the edit/plot window by pressing ok, then it will
appear) and call EEGLAB function statcond().

I wrote a simple function for testing ERP on STUDY. Download std_ErpCalc()
Unzip it, and place the folder under /eeglab/plugins and relaunch EEGLAB.
If you encounter a problem let me know.

I also heard that ERPLAB is a good tool to test ERP but I'm not sure if it
is compatible with STUDY.
