Mind Monitor

I am currently trying to create spectrograms with Brainwaves collected during a recording of Mind Monitor, and I am realizing that the PSD range of {-1:1} provided in the CSV of the recording is posing to be a little bit of an issue.

Is there anyway that the absolute brain wave values for a recording session can be written into the CSV or calculated using the PSD?
Thanks in advance.

If you want to make a spectrogram then you need to do an FFT of the 256Hz RAW EEG.
First set your "Recording interval" in Settings to "Constant", then you will have the data you need in the RAW EEG.

Thank you so much for replying James.

I just had a question about generating the spectrograms (I am using Python). Should I be using the averages of all four electrodes RAW EEG values, or rather construct a spectrogram per electrode? Thanks!

That's up to you and depends on if what you're looking for is in a certain region of the brain.

In Mind Monitor, the spectrogram shows AF7 and AF8 by default, but you can change it in the settings.
