Significance test frequency power decrease baseline vs stimulation

[Floris de Lange]

Dear Thomas, Jan-Matthijs and others,

Related to the post of a few days ago (error message undefined data or class
data.biol), it looks like this problem has been discussed already before on
the list: see
https://listserv.surfnet.nl/scripts/wa.cgi?A2=ind0610&L=FIELDTRIP&P=R23621

I copy/paste the relevant bit below.

Best wishes,
Floris
