[FieldTrip] Why use LCMV + Hilbert envelope vs. DICS?

[Peter Goodin]

Hi Fieldtrip list, 

Please excuse a possibly silly question, but I'm hoping someone can explain what difference occurs using DICS vs. LCMV + narrow band filter + hilbert envelope + mean amplitude over time (eg. Brookes et al., 2011)? I notice the latter is the preferred method for functional connectivity using MEG, but as far as I understand it, wouldn't the two produce a comparable result? Are there occasions where one is better than the other? 

Thanks, 

Peter
