<p class="MsoNormal"><span style="color:#1F497D">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The bottom figure shows what we get with the default spectopo – this is what seems to be clean EEG with approx. 80 second duration from 64 electrode data. The code is:
<o:p></o:p></span></p>
<p class="MsoNormal">figure; pop_spectopo(EEG, 1, [0 80000], 'EEG' , 'freqrange',[2 60],'electrodes','off')<span style="color:#1F497D"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">perhaps this is line noise or something – if we run a filter the noise is gone. But what concerns me is that if we use if we use some other parameters we can
get rid of it, without any filter, e.g, the top figure is generated by:<o:p></o:p></span></p>
<p class="MsoNormal">figure; pop_spectopo(EEG, 1, [0 80000], 'EEG' , 'freqrange',[2 60],'electrodes','off','winsize', 1024, 'nfft', 1024);<span style="color:#1F497D"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">so - we would be happy to know what are the recommended parameters for spectopo.
