Hello SPMers-
I'm trying to create event-related, 1st level models that occasionally have empty regressors (where subjects made no mistakes). I see a solution suggested here to make a dummy regressor with a single value at the final time point:

but am curious if that's still the best method in SPM12. AFNI, for example, has a "-allzero_OK" option in 3dDeconvolve... perhaps something like that was added in SPM12? I appologize in advance if this is obvious somehow; I'm just gettin back into SPM12 so am not aware of all the new changes since SPM8. THANKS
