[Eeglablist] Component Spectra at All Channels

[Marco Montalto]

Dear Makoto,

Thanks for your reply. I chose Plot > Component Spectra and Maps

Settings modified: Electrode number to analyse = 0 (whole scalp)
				 Percent data to sample = 100
				[Checked] Compute comp spectra [Unchecked] (data-comp) spectra = Unchecked

Thanks once again and looking forward to your reply.

Regards,
Marco
