[FieldTrip] RV: sloreta doest not get unity source variance

[Yiyao Ye Lin]

Dear researchers,

 

After reading the sLoreta theory, I attempted to understand the sloreta
implementation detail. I attempted to obtain the source covariance matrix,
and I could not get the expected unit variance. To do this, I attempted to
calculate by two ways:

a)       lf'*invG*lf after line 268 of ft_inverse_sloreta

b)      lf(:,ii)'*invG*lf(:,ii) at line 267 of ft_inverse_sloreta

For this, I used EEG signal with average reference. 

What's wrong? How can the unity variance of source variance matrix? 

 

Best regards
