DEMO2 demonstrates the use of the data set III from the BCI competition 2003 for The demo shows the offline analysis for obtaining a classifier and uses a jack-knife method (leave-one-trial out) for validation. AAR parameters are extracted References: [1] A. Schl�l, B. Kemp, T. Penzel, D. Kunz, S.-L. Himanen, A. V�ri, G. Dorffner, G. Pfurtscheller.
