[Eeglablist] rectify eeg signal

[Makoto Miyakoshi]

Dear Javier,

Hello.
For each calculation, find the following buttons in the EEGLAB main GUI.

FFT: Plot-Channel/Component spectra and maps, or properties
epoch: Tools-Extract epochs
rectify: (There is no function supported for this, I believe. In the
command window, type 'EEG.data = abs(EEG.data);' and your EEG data is
rectified.)
average: Plot-Sum/compare (comp) EEG

There is also EEGLAB tutorial manual.

I hope it helps.

Makoto
