Correcting EEG electrode's locations on mne_analyze

Hi MNE users,

I am trying to visualize the real locations for EEG electrodes on
mne_analyze using the viewer. I can see the electrodes on the scalp
surface but not the real distance of each electrode to it. I am trying to
check that my electrodes were correctly digitized and wanted to know if
there is a way to correct their locations in case such a problem occurs.

Thanks in advance for your comments,

When you do the coordinate system alignment, the electrode locations
are also shown but not with a different color, unfortunately.
For the forward calculation, the electrodes are dropped to the nearest
point on the scalp surface so that slight error in the digitization
should not be a big problem, especially because the EEG patterns are
quite widespread.
