[FieldTrip] relative power estimation

[Marta Andujar]

Dear all,
I am performing a time-frequency decomposition via Morlet's Wavelet. My
question is very basic and it concerns the estimation of the power. I
went through different tutorials, and I am a bit confused about the
normalization. In every tutorial I saw, the normalization is implemented
before plotting the results.I am using the 'relative' option, so that for
each frequency of interest and for each time-bin, the power is expressed as
the ratio between the raw power and the power averaged over the baseline
period. However, I would like to have my TRF results expressed as relative
power before plotting. Is there a way to get what I am looking for? Or
should I write my own code in order to get the relative power? My final
goal is to extract different frequency-bands, and I guess that for each of
these I should normalize against the power averaged both over the baseline
period and over the frequencies defining the band of interest. Is it
correct?
Thank you in advance
Marta
