<br>
I'm looking for a way to plot a frequency-band activity (let's say average alpha 8-12Hz) for 64 electrodes into a topographical map for each subjects (and eventually on a subject average) at a specific time point. The next step is then to have several of these maps for several chronologically different time point. Is there any option to do this, or a direction I can follow to make a script?<br>
<br>
Thanks a lot for anything that helps.<br>
