Hi
I tried to run ft_scalpcurrentdensity on my 128-channel EEG data (Cz recording reference) to estimate scalp current density using the surface Laplacian. When I ran it, I received this warning message:
Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 3.554116e-08.
Do you have any idea why I get this message and should I be concerned about it?
Thanks,
Valeria
