Sampling rate or time delay
Posted: Thu Oct 13, 2016 3:44 pm
Hi. I would like to ask a question about Actiview Software. When I open and read the bdf files for my subjects, I see less events (half) than the ones sending from my script. The events in each trial are different based on the frequency I send (8, 20, 33). When I calculate the frequencies from bdf files are also half. Could it be that I have chosen wrong sampling rate (I chose 2048 Hz) or could it be a delay in the timing? Why half of the events are read?
Thank you
Thank you
