Hi MNE users,

I am using mne\_inverse\_operator command. The bad channels from my  
observations, eeg data only, are different from those of the noise  
covariance matrix. Does anyone know how mne\_inverse\_operator work under  
this situation? Does MNE uses only the good channels in both files? I want  
to double check this is the case.

Thank you very much for your comments and Happy Holidays!!

Best,
