I am trying to send a different event marker (to an EEG signal) depending on my participant’s response (e.g. send 1 if they pressed button 1, send 2 if they pressed button 2, send 3 if they pressed button 3) . Does anyone know how to do this? It seems that I can only get a response marker but that can’t be modified depending on the button participants pressed. I assume I could do this with the feedback function but I don’t know how.
Any help is greatly appreciated.
