Dear all,
I get an error message when I try to perform DCM inversion after coregistration and forward modelling.
As far as I understood I have to do the coregistration with the individual MRI and forward modelling first (by clicking 3D source reconstruction) and DCM afterwards. When I click the DCM button, I get the attached error (trials and data are not consistent).
I intend to do DCM for evoked responses and my d.mat structure contains two trials: baseline and activation.
It is possible to perform DCM inversion with the default MRI when I load the EEG data and set trials to 1 2 (effect 0 1), but how can I use the individual MRI together with my data?
Best regards,
Fabienne
