Hello Ilya,<div><br></div><div>I've had a similar issue, and it's not clear from documentation or eeglablist</div><div>what exactly is needed. I think more detailed step by step instructions</div><div>are needed to make it so that users don't get stuck at these basic steps.</div>
<div>I've developed some workarounds, but I have not been doing source localization.</div><div><br></div><div>1. First if the data is re-referenced or average referenced before going into eeglab,</div><div>then don't export the reference channel from Netstation.</div>
<div><br></div><div>2 Second you may want to use a different file of electrode locations</div><div>that matches your data, i.e., has 131 locations, or that recognizes fiducials.</div><div><br></div><div>Good luck and do let us know what you figure out so others don't suffer!</div>
<div><br></div><div>All the best,</div><div>Tarik</div><div><br></div><div><br>********************************************************************************************************************************<br>Tarik Bel-Bahar, PhD<br>

o.k. but as soon as I try to accept these channel locations by pressing OK
button in Edit EEG channel window I get the following message: „The number of
