I hope you do not mind my contacting you out of blue.
I am Masataka Wada and conducting EEG analyses using MNE-Python.
Recently, I try to source reconstruction from the preprocessed .set file
data.
I have followed the tutorial, but in "Source alignment and coordinate
frames",
the location of EEG sensors is displayed far from the head-model like the
figure below.

When I use sample data ('sample_audvis_raw.fif'), there is no problem like
below.

Is it possible your electrode locations are in millimeters instead of
meters? MNE-Python expects all locations to be in meters. One way to change
this would be to use raw.get_montage(), change the channel positions,
create a new montage with make_dig_montage, then call raw.set_montage using
the modified one.

What is the reason for this?
Best regards,
