<div>I want to know the power spectrum generated by EEGLAB both in a STUDY and in each dataset seperately is using absolute values or relative values.</div>
<div> </div>
<div>If it based on relative values than how a frequency range can be known?</div>
<div> </div>
<div>If it is based on absolute values than how can I calculate the relative power in EEGLAB?</div>
<div> </div>
<div>Thanks</div>
