Computing relative brain waves in MATLAB

Post by pmarting »

Hi James, thanks for creating this amazing software!

I just bought a muse band and I am looking forward analysing my own data. (I have programming expertise)

I tried the MATLAB code to plot the processed waves. I was wondering how may I implement the relative waves to plot them! I tried smoothing each curve and looking at each curve's derivative but this doesn't give me the same output as your online tool. Should I also look at the other waves as well?

I am also wondering if there is something else that might be interesting to implement. Perhaps plotting the DFT as given in the app? I am happy to share all my code in GitHub if it is interesting for the community.

Thanks in advance!

For relative brainwaves see: [https://web.archive.org/web/20181105231 ... and_Powers] - alpha_relative = (10^alpha_absolute / (10^alpha_absolute + 10^beta_absolute + 10^delta_absolute + 10^gamma_absolute + 10^theta_absolute))
