[Eeglablist] When using DIPFIT, what are the units of the calculated dipole moments?

[Peter Elovsson]

Dear all,

I am trying to use DIPFIT in EEGLAB at the moment. However, when I
perform dipole source localisation, all of my dipoles have moment
magnitudes in the order of 10000s, and there is no corresponding unit.

I would have assumed the unit for moment is nAm, however this wouldn't
make much sense considering how large my calculated moment magnitudes
are.

It could be that my co-registration isn't accurate enough which is
causing such large and unreasonable moment magnitude (if the unit is
nAm), but I am unable to reduce the mean distance between template
electrodes and measured electrodes from the study I'm using to less
than 5mm.

Can anybody help clarify, is the co-registration the problem, or is it
that the dipole moment magnitude calculated by DIPFIT is a strange
unexpected unit and that's what's causing my problem?

Thanks so much,
Peter
