[Eeglablist] Extracting average ERSP values for statistical analysis

Dear Nikola,

Follow these steps.
1. Open 'edit/plot cluster' and show ERSP/ITC for all clsuters.
2. Close 'edit/plot cluster'. This updates the EEGLAB (notice the size
changes).
3. From Matlab workspace, open 'STUDY.cluster(1,a).ersp... ' for clsuter a.
You'll notice that it is a cell containing nxm contents, and n and m
corresponds to your variable1 and variable 2 (check this carefully if you
have 2x2 or 3x3...)
4. Your freq and time scales are also located under 'STUDY.cluster(1,a)'

Actually I have answered the same questions more than several times, and
you may want to check them in the list archive. If you have more questions
let us know.

Makoto
