Dear SPMers,
specifying efMRI designs - is it possible to use 0.5 scan increments for
the conditions? I have tried so, SPM accepted the trial onsets of half
scans without any problem but the result was not ok (it collapsed at
half of the session modelling). Do I have to start with 0.5 or 1.5 for
the primary vector of onset?
TIA-
andreas
