I was wondering if EEGlab can be used to analyze and/or provide topographical mapping of ERP/P300/VEP data. If so, in what data forms - we are using primarily ascii, .dat files extensions. Lastly, what type of analysis results from this? Thanks, Robert Coben, PhD, BCIA-EEG, QEEG-D 1035 Park Blvd, Suite 1C Massapequa Park, New York 11762
