Coordinates for channel localisation

[MarcoRotonda]

Hi,
I tried to apply the coordianate I extrapolate from a file I had of a 10-5 system but I had an error:

[ ERROR ] At time 167772160 (0xa000000)<Box algorithm::2D topographic map> Coord
inates of electrode #0 (0x0)(AF3), are not normalized, aborting model frame elec
trode coordinates computation
[WARNING] Box algorithm <2D topographic map> has been deactivated because proces
s phase returned bad status

and the same for 3D topographic...

What does it means: "are not normalized"?

I've attached the file.

Dear MarcoRotonda,

normalized means that the length of the actual position vector should be 1. The electrode localization are projected on the scalp from a unit sphere.

Tell me if it helps.
