Figure 8

Performance of the classification in the post hoc online analysis and the offline analysis. The empirical chance level of 57.5% for 120 feedback trials is depicted with a dashed line. The subject labels describe the channel pair which was used for the simulated online and the offline analysis. The last two bars show the group mean which show accuracies above chance level for both analysis procedures.
