[FieldTrip] Creating a BEM volume conduction model of the head for source-reconstruction of EEG data related question

[Anik Das]

I was working with "Creating a BEM volume conduction model of the head for
source-reconstruction of EEG data" founded from:
http://www.fieldtriptoolbox.org/tutorial/headmodel_eeg_bem/ .I've some
questions regarding this
1. Is the head-model(only for vol.bnd(3) coordinates) origin in figure is
(0,0,0) ?
2. if so, does the x, y axis for origin (0,0,0) intersect the points  ‘Nz’,
‘LPA’ and ‘RPA’ like ctf coordinate system(

)?
