<div class="gmail_extra">Hello Ida,<br><br>If your Excel sheet is already in the correct format for spherical data, and saved with the proper extension (for spherical data I believe it needs to be a .elp or .sph file) , then you can import the locations from the command line using <br>
<div style="margin-left:40px">readlocs(filename)<br></div>or from the EEGLAB interface you can select <i>Edit > Channel locations > Read locations</i><br><br>See <a href="http://sccn.ucsd.edu/wiki/A03:_Importing_Channel_Locations">http://sccn.ucsd.edu/wiki/A03:_Importing_Channel_Locations</a> for more information. A sample of one of my location files is attached; mine are in Cartesian coordinates (.xyz files) so yours will probably look a bit different.<br>
