Dear All.
actually I am working on a DCM study an used amongst others the function spm_dcm_fmri_check to check my results. In the description of this function it says, "one would normally expect to see one or more extrinsic connections with the strength of 1/8 Hz or greater.
My question is, if there is any literature, so I can understand, why the connection strength is fixed on this specific value?
Best regards,
Inken
