Source reconstruction of motor imagery data?

04 November 2020 1 5K Report

I am using DICS beamforming in Fieldtrip to beam my ERD effect( event-related desynchronization, decrease in power during intention to move/ movement) in 3 frequency bands. I get power activations using that in Fieldtrip. But, I need a broadband source time series in regions of interest that I can use for connectivity analysis. How can I find that? It's mentioned on Fieldtrip website to use LCMV beamforming in time domain using ft_timelockanalysis, but I don’t think there is any time locked effect in my data between different conditions, so what should be the approach to get source time series.
