<div dir="ltr">Hi Marta,<div><br></div><div>It's not clear from your question whether you do or do not want to baseline correct power before plotting - with which I assume you mean not doing it in the plotting functions but instead creating a data structure which has had baseline correction applied. If so, ft_freqbaseline is what you are looking for. If not, then I am afraid I do not understand that part of the question.</div><div>Regarding the question whether or not you should apply a baseline correction, that would depend on what you want to do. "My final goal is to extract different frequency-bands" is not specific enough to really give an informed response to that.</div><div><br></div><div>Best,</div><div>Stephen</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Op ma 14 sep. 2020 om 15:32 schreef Marta Andujar <<a href="mailto:marta.andujar@uniroma1.it">marta.andujar@uniroma1.it</a>>:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Dear all, <div>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?</div><div>Thank you in advance</div><div>Marta</div></div>
