I would like to apply DCM for my resting state fMRI data.
But there is no clear explanation of this issue by using of SPM. The SPM manual simply explains howto but there are lacks of some information. For example, in specifying DCM step, I do not know what to do after entering TE because manual did not say about "modulatory effects", "states per region", "stocahstic effects", "center input", and fit timeseries or CSD.
I (and everyone may) need kind walk-through description with a basic information about each step.
Any comments would be appreciated.
