Dear SPM experts, I am trying to use for the first time SPM because I would like to test different models of interaction between brain areas using the Dynamic Casual Modelling approach. In this case I have resting data. I have two groups, with 30 subjects each. For each subject of the two groups I have already extracted the source activity of each ROI. However I am not that familiar with SPM. Once I have extracted the time series of the ROI, which I believe should be in .mat format, what should I do next? I trained myself by fitting resting state DCM following the chapter 38 of the manual on resting state fMRI data. However I am afraid that the DCM uses the hemodynamic response function, and that may not be appropriate in my case, since I have an EEG activity. Do you have any tutorial or suggestion on how to implement a resting state DCM for EEG data?
Thanks
