A Combination of Pre- and Postprocessing Techniques to Enhance Self-Paced BCIs

Table 2

Individual performance while the dwell time and threshold are automatically selected in training phase, the selected values also are written for each subject in 3 different combinations of runs. Run no. n shows the test run number.
