<div dir="ltr"><div><div>Hi Giulia,<br><br></div>Baseline correction method 'relchange' computes the relative change according [ (task-baseline)/baseline ], i.e. a ratio centered around zero. If you multiply with 100, you get the relative change (from baseline) expressed in percentages.<br>

I have a quick question.<br>
I've performed a Time Frequency<br>
Analysis with ft_freqanalysis using 'wavelet' as a method and 'relchange' as a<br>
baseline normalization for the plot.<br>
What is the unit for the ERD/ERS in the<br>
plot?<br>
Thank you so much for you help<br>
Giulia<br>
