<div dir="ltr"><font face="tahoma">How do you create a spectral map (of power vs. frequency) for select channels (all on one plot)? I have yet to figure out how each variable is stored in EEGlab so that I can write code calling on particular ones. Using the
pop_functions, you can plot power spectra for individual channels separately using the "channel properties" option, but I need multiple channels on one spectral plot.
</font></div>
<div dir="ltr"><font face="tahoma"></font> </div>
<div dir="ltr"><font face="tahoma">Also, is there a way to calculate the max(power) on these plots? I am looking at peaks in alpha and beta ranges and am trying to quantify the max value of each peak. Is there a command or function or something other than
manually using the data cursor within the figure menu that I could use to do this?</font></div>

<div dir="ltr"><font face="tahoma">Thanks so much!</font></div>
