Hi Gang,

When you say that "FMRI data are not suited for causal modeling through GCA" do you mean all kinds of fMRI data (including resting state) or are you specifically referring to task-based fMRI?
I thought the afni tools 1dGC and 3dGC addressed some of the issues of temporal resolution, or am I wrong?
Are you suggesting that we should not perform Granger Causality with any kind of fMRI data?

Best regards,
Sam
