hi everyone,
my intention is to steal some code of the dipolefitting function to
model source activity of raw EEG data (keep fixed locations, just
analyse changes in dipole moment; i have a leadfield matrix using
prepare_leadfield). to test things i used a visual ERP data set as
outputted by timelockanalysis.
the waveforms look fine, i just get really huge values: ~14000 as
maximum dipole moments (the N1 is about 6000). so my question is what
units i have? do i have to scale by 1000 to get nAm (14 & 6 nAm would
make sense) or do these values imply that something has gone
completely wrong.
thanks in advance,
nathan
