[FieldTrip] subspace projection

[Jan.Hirschmann at med.uni-duesseldorf.de]

Dear fieldtrip community,

 

In LCMV beamforming there is an option cfg.lcmv.subspace=X. Does anyone have experience or recommendations regarding this option? Is there a publication in which the rationale is described? From looking at the code it seems that data and lead field are projected onto a subspace spanned by the first X singular vectors of the covariance matrix (correct me if I'm wrong). Seems helpful in my case but I am hesitant to use it without knowing anything about it.

 

Thanks for any comment!

Jan
