If you create STUDY you can analyze them with GUI. If you code in Matlab you can use output from functions (spectopo).</div><div><br></div>> Q: Is that any tool in EEGLAB which help me to correlate the specific band power v/s cognitive change during tasks.<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">No I don't think so.</div><div class="gmail_extra">Cyril Pernet's LIMO may does it.
