<br><div class="gmail_quote">Hello,<br><br>I am collecting EEG data from a SynAmps RT 128 channels. I am using a QuikCap NSL, which although has 128 electrodes, does not follow standard 10-20 localisation.<br><br>I'm trying to create a layout to visualise my data using the template fiducials of the cap. My script currently looks something like this:<br>
<br>cfg =[];<br>cfg.elecfile='QuikCap_128_NSL.sfp'<br>cfg.rotate=0;<br>cfg.projection='polar'<br>lay=ft_prepare_layout(cfg);<br>ft_layoutplot(cfg)<br><br>However, the electrodes seems to be shifted towards the back of the head. The layout I get can be seen in the FieldTrip_Layout figure attached. I have tried to realign the electrodes (using ft_electroderealign), but I get similar results.<br>
<br>Has anyone ever had a similar problem?<br><br>Please find attached the 'QuikCap_128_NSL.sfp' file with the fiducials and a .png figure of the electrode positions taken from NeuroScan's website.<br><br>Thanks in advance for the help.<br>
