[Mne_analysis] Dspm and loose orientation solution

[Hari Bharadwaj]

Hi All,
  I have a question relating modeling the null distribution in a dspm map with an inverse operator that is not obtained using --fixed.
    When mne_make_movie is run with --spm option but without the --signed option which of the following is done?
1. Noise normalize each component first and then do sqrt(sum of squared x,y,z) or
2. Do sqrt(sum of squared x,y,z) then noise normalize

Thanks,
Hari
