Hi Francois,
I hope you are fine,
Kindly find in the attachment a txt file with positions of nasion and pre auricular points
213 = dig. point cardinal 1 ( -56.1, 0.0, 0.0) (pre auricular)
213 = dig. point cardinal 2 ( -0.0, 73.1, 0.0) (nasion)
213 = dig. point cardinal 3 ( 50.3, 0.0, 0.0) (pre auricular)
And the transformation matrix MEG helmet --> head
222 = transform device -> head

-0.043777 0.921912 0.384919

Thank you in advance!
