data collecting process..<br><br>for EEGlab software i got few questions as below: <br>1) do i need to mean corrected my data first before export to EEGlab?<br>2) can i export separate wave (Delta, Theta, Alpha and Beta) for RHS and LHS or just import 2channels (RHS &LHS without separate it)<br>3) actually, the results from ICA are the clean wave or the aftifact wave that we want to abolish?<br><br>thank & best regards..<br><br></div></div><br>Send instant messages to your online friends http://uk.messenger.yahoo.com </body></html>
