importing vol and grid for beamforming (ft_sourceanalysis)

[Dahlia Sharon]

Hi,

I would like to use beamforming, and have the forward solution and BEMs produced from MNE/FreeSurfer. Rather than resegment the data from scratch, I would like to import the results I already have.

Reading the tutorial and reference documentation, I see that I need to give ft_sourceanalysis a cfg structure containing vol and grid fields (the latter being itself a structure). However it isn't clear to me what these fields should contain exactly.

Can someone clarify please?

Thanks!
Dahlia.
