Dear EEG experts, 
<div><br>
</div>
<div><br>
</div>
<div>I am using a 64 channel acticap system. Two additional electrodes placed on Az and FCz serve as ground and reference, respectively. I am recording the data with BrainVision recorder. Ref and ground are not in the workspace. </div>
<div><br>
</div>
<div>When I load the bv file into EEGLAB, consequently only 64 channels are available, Az and FCz are missing. </div>
<div><br>
</div>
<div>Do you know of any ways how I could reuse the FCz for subsequent offline re-referencing etc? Perhaps by including it in the workspace beforehand? BrainVisionAnalyzer seems to offer the option of reusing the reference channel. </div>
<div><br>
</div>
<div>I am very grateful for help. </div>
<div><br>
</div>
<div>Kind regards, </div>
<div>Clemens </div>
