[Mne_analysis] compute_source_psd_epochs 'noisenorm' error

[Rockhill, Alexander P.]

I figured it out... it was the prepared = True keyword argument. I hadn't prepared the inverse. It's always the simplest things... thanks for all the help.

Hi Alex,

Please feel free to pass by my office, if you want to debug it together.

Thanks
