[FieldTrip] ICA before beamforming -> change in gradiometer -> workaround?

[Frederic Roux]

Dear all,

I am using ICA prior to beamforming for artefact cleaning (EOG & ECG).

After running ft_componentanalysis I noticed that the gradiometer structure
is removed from the data, which is required by ft_sourceanalysis.

In a prior post I read that one could just add the grad structure from a previous version
of the data before the ICA cleaning.

Can anyone tell me if this is the best solution, or if there is any other strategies out there?

Best,
Fred
