[Eeglablist] Averaged waveform across electrodes from Netstation data

[Dott. Rosario Romualdo Federico]

Hi everyone,
I'm a PhD student (almost done!) in Pisa (developmental neuroscience), working atm on n170. 
I'm using a GES 300 of EGI, and if I'm right I guess that with the tools provided in Netstation is still not possible to get the waveform (even if you can extract numerical data) from a chosen number of electrodes. 

My question to you is: what is the easiest  way of getting the average waveform from a ROI of any given number of adiacent electrodes?
(I basically never used eeglab, but I learn fast, and I have to be fast!:))

Thanks a lot in advance
