The dataset IIIb consists of the three recordings S4, X11 and O3VR with 1080, 1080 and 640 trials, respectively.
Due to a mistake, the trials 1-160 and 161-320 in O3VR are equal. This means, in 2x75 (out of 640) trials one can obtain the labels of the test set by looking at the label of the corresponding trials. In order to remove the repetition of testing data, the first 160 trials (containing another 43 testing trials) will not be considered in the final evaluation. Accordingly, the number of testing trials in O3VR will be reduced to 202 (out of 480) trials.
