[Eeglablist] Spectopo Function Negative Power Values

[Courtney Jimenez]

Hi all,

We are using eeglab's spectopo function to calculate power spectral density
estimates for our data. However, we're getting large negative values in
many channels across many frequencies.

How can we correct this?

We use the following code from the matlab command line:
spectopo(EEG.data(:,:),0,EEG.srate,'freqrange',[4 50],'title',EEG.setname)


Thanks,
Courtney
