**Figure A1.** Kruskal–Wallis comparison between the machine learning models tested. The plot shows several combinations of features calculated from the channel A2 recorded from the CP. There are statistical significant differences between the groups labeled with red and the group labeled with blue, between the groups SVM-Entropy and SVM-AllFeat and the groups labeled with blue and gray. In general there are statistically significant differences, when the projection of the horizontal lines of a group over the horizontal axis does not have any interception with the projection of another group.

**Figure A2.** Kruskal–Wallis comparison between the machine learning models tested, considering several combinations of features extracted from the channel A1 of the RC dataset. There are statistical significant differences between the groups labeled with red and the group labeled with blue. In general there are statistically significant differences, when the projection of the horizontal lines of a group over the horizontal axis does not have any interception with the projection of another group.
