[FieldTrip] event related fields from source space

[Rojas, Don]

Kaelasha,

That is exactly what you are looking at for data.avg.mom (x y and z dipole moments for your vector beamformer solution, for each grid point in your 3d source space).

Best,

Don

FieldTripers,

I am wanting to reconstruct event related fields from source space and have been beamforming with ft_sourceanalysis using cfg.method='lcmv'.

I have not been able to find any clear instructors on this, but can any one tell me, does ft_sourceanalysis output 'data.avg.mom' contain the averaged ERPs reconstructed in source space?

data.avg.mom appears to be a column of cells, one cell for each point in my 3d grid, with each cell containing 3 time series (ERFs), one for each 3d orientation??, x, y, z?

Can any one tell me if this is indeed what I am looking at in data.avg.mom?
