Hi,
I'm using DCM on fMRI data with a block design. The DCM estimation procedure only appears to extract the stimulus onsets from the SPM.mat - I can't see that it takes into account the durations of the stimuli. Does anyone know if it has a default duration? And if so, is there any way to alter it so that it matches the duration of our blocks?
Any help on this would be great!
