However, EEGLAB will not be able to use that information. It might also create problems if you have trying to reference these two bipolar channels (EEGLAB cannot do it (in fact it cannot be done) and I am not sure EEGLAB will return the appropriate error). You should simply declare your channels as Cz and Pz and put the dataset comment your bipolar montage information.</div><div><br></div><div>Best,</div><div><br></div><div>Arno </div><div><br><div><div>On Aug 29, 2012, at 8:19 AM, Max Docker wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div class="hmmessage" style="font-size: 10pt; font-family: Tahoma; "><div dir="ltr"><span style="color: rgb(102, 102, 102); font-family: Arial, Helvetica, sans-serif; font-size: 12px; background-color: rgb(255, 255, 255); ">Hi,</span><br style="color: rgb(102, 102, 102); font-family: Arial, Helvetica, sans-serif; font-size: 12px; background-color: rgb(255, 255, 255); "><br style="color: rgb(102, 102, 102); font-family: Arial, Helvetica, sans-serif; font-size: 12px; background-color: rgb(255, 255, 255); "><span style="color: rgb(102, 102, 102); font-family: Arial, Helvetica, sans-serif; font-size: 12px; background-color: rgb(255, 255, 255); ">I am using a bipolar montage for my eeg recording.
