Inconsistency between seconds recording in OpenBCI_GUI and seconds of saved data in .txt file
Hello,
Maybe I am missing something, but I am streaming data from my Ganglion using OpenBCI_GUI for 20 seconds (timing it with an external chronometer); and when I get the raw eeg data saved in the .txt file and I divide the number of samples by the sampling frequency (200Hz), I obtain around 13 seconds instead of 20 (much less).
That is, in Matlab: length(raw_eeg_data) / 200
It sounds like I am missing something but can't figure out what... any clues of what it is?
Thank you.
