[FieldTrip] Beamformer for ERP data

[IMALI THANUJA HETTIARACHCHI]

Dear Fieldtrippers,

I am trying to do a LCMV beamformer analysis using the ft_sourceanalysis for a ERP data set.  Finally I intend to extract the source waveforms using virtual electrodes.

But as we can only do meaningful source localisation for a small time interval say (50ms), how can I construct the source time course for a longer  post stimulus period (say 500ms)after doing beamforming for shorter (50ms) time intervals?

Many thanks in advance

Kind regards
Imali
