[Mne_analysis] Applying the fMRI weighted w file on the inverse operator

[Thinh Nguyen]

Hi MNE users,

I'm currently trying to applying a a prior source constraints via the fMRI
weighting file. But according to MNE documentation:
 "It turns out that the fMRI weighting has a strong influence on the MNE
but the noise-normalized estimates are much less affected by it."
(http://martinos.org/mne/stable/manual/mne.html#cbbdijhi)
Can anyone please explain to me why this is such a case, maybe in both
mathematical and intuitive sense. Thank you very much in advance.
