[Eeglablist] pop_spectopo specified channels, winsize and nfft

[Nike gnanateja]

Dear Alex,
 I think what you are missing here is the 'plotchans' option. It should do
the trick

figure;[spectra,freqs] = spectopo(EEG.data, 0, EEG.srate,
'winsize',256,'freq', [6 10 12],'freqrange',[4 14], 'nfft',
512,'chanlocs',EEG.chanlocs,'electrodes','off','plotchans',1:8);


Regards,
Nike
