Hi all,<br> I'm working with spatial filter (i.e. IC and CSP).<br>Let us denote with X the EEG raw signal and with Z the projection obtained with the filter S:<br> Z = S * X<br>In this case the rows of matrix S are called "Filter"<br>
If we write:<br>X = (S^(-1)) ' * Z <br>with the rows of (S^(-1)) ' = A we denote the pattern.<br>Does anybody know what's the difference between Filter and Pattern scalp-plot ?<br>What information gives the Pattern Plot?<br>
<br>Thank you in advance<br><br>Michele<br><br><br><br><br><br><br><br clear="all"><br>-- <br> -Michele-<br>
