Hi,
<div><br></div><div>I use the FFT power spectrum function for a single channel and it outputs a nice spectrum in dB that looks qualitatively very much like it should.</div><div>However, when I compare with the values that I calculate by hand with matlab or Spike2 it seems that the EEGlab power spectral values are always too high.</div>
<div><br></div><div>Does anyone know why this is and how to correct for it?</div><div><br></div><div>Thanks</div><div>Mike</div>
