[Mne_analysis] mne_make_eeg_layout ? for maxfilter

[dgw]

Hello,

Does anyone know what coordinate frame mne_make_eeg_layout uses when
calculating the sphere? I am trying to use this as an automated way of
providing an origin to maxfilter (which doesn't handle digitized
points of the nose and face well). My output is below. I am using MNE
2.7.3. Judging from the values it suggests that it is in the Head
coordinate frame, but if anyone knows that would help.

Thanks,
D
