Just had a couple of more questions for the DCM experts out there... Would I be right in saying that the DCM GUI for induced responses uses equivalent current dipoles to define the location the sources? Is it possible (and also technically correct) to run an induced DCM on files that contain sources that have been extracted via a virtual sensor (beamforming) ( iefffdspm8... files)? Also, assuming it is possible, what difference if any would this make to the observed and predicted TF plots? Any clarification would be greatly appreciated. Thanks, Andy
