How to process the raw data for ERP analysis?

[ty22]

Hi, I am using Muse 2016 and wish to analysis ERP (Event Related Potential) but the graph looks too noisy and it ranges from 0 to 1500 (uv, I think). Is there a way to smooth it so I get a cleaner graph and see the ERPs (P170, in this case)?

Thanks!

Your raw EEG data should be 850uV +-100, (aside from than blink interference). If it's wildly outside of that then you likely had a bad sensor connection and I'm not sure what you can do about that, other than running the study again. You could try dropping bad data and just doing an FFT on what's left, but I'm not sure how good you results would be.

Thanks. Is there any tool to do a bandpass filter to the muse monitor csv file?

Not that I'm aware of, no. However, the file format is super simple, so if you know how to code, it will be trivial to parse as a textstream. You could probably even do an Excel macro.
