Figure 3.

Example variations of PSD quantities of beta band calculated from 46 trials of a random subject in Dataset 1. Each subplot shows how the PSD varied for this subject depending on the selected choices within five methods. Each subfigure contrasts choices in one method keeping the other methods constant to default values. The default constant values were as follows: artifact removal = yes, EEG transformation = raw, filter = Butterworth, time window = 750 ms, method = Welch’s method. (a) Variations for artifact removal choices. (b) Variations for EEG transformation choices. (c) Variations for filter algorithm choices. (d) Variations for time window choices. (e) Variations for PSD estimation method choices.
