<div>Dear FieldTrip community,</div>
<div> </div>
<div>
<div>I am using ft_sourceanalysis on SSS preprocessed (neuromag) data. I wonder if there are any suggestions on how to set lambda in this case? My covariance matrix is rank deficient (rank 60, 306 sensors). I read in the mailing list that I would need to look at the eigenvalues of XX' and set lambda to be 1/1000 of the largest eigenvalue. However, I do not really understand why to divide by 1/1000?</div>
<div> </div>
<div>Every help would be very much appreciated,</div>
<div> </div>
<div>Thanks!</div>
