<div dir="ltr">Hi,<br><br>just to add to Stephen's answer - you can plot anything with topoplot (p-values, correlation coefficients,<br>mean spectral power etc.) - topoplot plots and interpolates given values, whatever these<br>
values are. The order of electrode-value pairings is determined by EEG.chanlocs<br>(this structure can be passed to topoplot).<br> </div><div class="gmail_extra"><br clear="all"><div>Pozdrawiam,<br>Miko³aj Magnuski</div>

<div dir="ltr">Hi Joaquin,<div><br></div><div>topoplot() is plotting the activity at a certain time (or an average over a certain time window) at all channels, and interpolated between channels. I've never used it to plot activity restricted to a certain frequency, although in principle I guess that is possible; I've only used it to plot the raw ERP amplitudes, though.</div>

<div dir="ltr"><div><div><div><div><div>Hi, <br><br></div>I´m not fully sure if I´m understanding how topoplot() works.<br><br></div>First
I thought that it was plotting the interpolation of all channel
spectrums at a given frequency, but then I found spectopo(), which I
have not yet tested it, but seems to do what I supposed topoplot was
doing.<br>
<br></div>I can´t understand what is topoplot plotting, <u>because if neither a frequency nor time is fixed </u>it can not be plot.<br><br></div>Please someone clarify my thoughts.<br><br></div>Thanks!</div>
