Double triggers in log?
Double triggers in log?
I'm running an experiment where I as the experimenter occasionally use the function keys to insert triggers; when I look at the status channel in EEGLab, there are two events when I do this--one with the code 511, and one with the code 255. I haven't been able to find any information about what code the function keys send, so can anybody tell me what's going on? More specifically, which event is the actual keypress?
