Hi folks, I'm trying to setup a P300 (vep visually evoked potential) detection with openBCI Cython. node.js for retrieving data, python scripts for bandpass filtering data. Tried several electrodes (Pz, Oz) and bandpassfilters (0.5-4 Hz, 1-15 Hz, 1-40 Hz) , but having trouble to detect any P300. Looking at 250-600ms after the event. Stimulus is a rather large darkblue icon flashing white (on black background). Any help or clues to this would be highly appreciated. Thanks, Michael
