<div apple-content-edited="true">Dear Makoto,</div>
<div apple-content-edited="true"><br>
</div>
<div apple-content-edited="true">Thank you very much for your response. I apologise for being insistent but I still have a question.</div>
<div apple-content-edited="true">Assuming I accept interpolation as the only solution, I do not have clear how to do.</div>
<div apple-content-edited="true">I usually don't use the GUI. I do the interpolation for bad channels by using the command pop_Interp(EEG, [channel], 'spherical'). </div>
<div apple-content-edited="true">However, this works fine if the (bad)channel exists. </div>
<div apple-content-edited="true">But in this particular case, Cz is removed from the data. </div>
<div apple-content-edited="true">Once I set Cz as reference electrode, I move from 64 to 63 electrodes and channel 48 (which is usually Cz) becomes C2. </div>
<div apple-content-edited="true"><br>
</div>
<div apple-content-edited="true">My question is, what I should add to the command in order to restore the Cz channel as channel 48 (even though as interpolated channel) and go back to 64 channels?</div>
<div apple-content-edited="true"><br>
</div>
<div apple-content-edited="true">I hope this makes sense.</div>
<div apple-content-edited="true"><br>
</div>
<div apple-content-edited="true">Many thanks</div>

<div>After average referencing you can interpolate the channel to generate your reference channel from main GUI 'Tools' - 'Interpolate electrodes'. You need to have a dataset before rereferencing though to copy its channel info.</div>

Dear all,<br>
<br>
I have Biosemi BDF data file. 64 Channels and reference channel Cz.<br>
My problem consists in retaining the reference channel in my data.<br>
The older version of eeglab9_0_4_5s does that by default.<br>
The version 11_0_4_3, instead, seems to separate the reference electrode from the others and, after computing the average reference, to definitively remove it.<br>
I would like to know what I would be supposed to do to retain the reference channel in my data with this version.<br>
<br>
I thank you very much for any help,<br>
<br>
Best Regards<br>
<br>
