Hi everyone,
I’m wondering that is there any way to calculate the level of relaxation or calm.
for the input: I use app EEG101 from google play store to get data format .csv .So I have a table like this:
the value Power spectral density for each frequency(from 1Hz to 128 Hz) in every milliseconds.

Can anyone help me out? thanks
