[Mne_analysis] appropriate way to combine intrasubject dSPMs?

[Dykstra, Andrew]

Hi all,

What is the most appropriate way to combine intrasubject dSPMs, e.g. 
multiple runs of the same task within the same subject in which I cannot 
assume that the gain and noise covariance matrices are equivalent across 
runs.  Is it as simple as averaging the resulting dSPMs from each run.  
This would seem to make sense for the raw current estimates, but I'm 
unclear on the noise-normalized estimates.

Thanks in advance,
Andy
