Dear Nikos,

alpha band is usually 9-11 Hz (although it may vary). Using the spectopo function, you may plot the spectrum at 10 Hz and this should give you an idea of the power in the alpha band distributed across all channels.

Best regards,

Arno

> Hello, Im looking a way to calculate power spectrum for alpha band on a set of subjects on a set of epochs for two channels and compare anyone has any idea ? I use spectopo but it calculates spectrum untill 250 hz not alpha band. Another problem i have is that the spectrums if i calculate right give pretty much the same spectrum for different conditions but that doesnt make sense because i want to compare the spectrums for different conditions
