The channel in your montage and in the model must have (approximately) the same 3-D location. In some cases -- when your montage and the model use the same channel coordinates -- registration is not required. EEGLAB will attempt to detect automatically which coregistration is required -- in case you are using standard channel locations -- but it is always good to double check.</div><div><br></div><div>Best,</div><div><br></div><div>Arno</div><div><br><div><div>On Jun 1, 2012, at 5:17 AM, Hui-bin Jia wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"><div><font size="1" face="Times New Roman">Hi,everyone</font></div>

In the first solution, "no co-registration is required". But in the second solution, we will need to align or co-register our electrode locations with the head model. And the solution for the sample dataset(eeglab_dipole.set) is the first solution.</font> </span></font></font></div>
