[Mne_analysis] Source Localization

[Diptyajit Das]

        External Email - Use Caution        

Hi!,
I don't have much experience with resting state data but I am not sure if
you can use a noise covariance matrices created from the raw data for
distributed source methods (e.g., dSPM or MNE) . Don't you have empty room
data?
best,
