used to train the LDA classifier. At the end of the training, you will have an estimation of the classifier performance printed in the console. If this performance is lower than 70%, just run a new 4-online session to have better results. Note: in order to run this scenario, the spatial filter should have been trained using 2-train-xDAWN !
