Dear AFNI,
I am planning a fast event related design. TR=3sec, duration=12 min, 2 stimuli types, 40 trials each. mean ISI=6sec, ISI range=3-12sec.

I am debating two designs. One has each stimulus time-locked to the start of the TR, the other has each stimulus with a random temporal jitter (0-500ms) from start of TR.

I am trying to use 3dDeconvolve -nodata to estimate if temporal jitter would significantly affect design efficiency. But when using both -nodata and -stim_times options, how do I specify the total duration of the experiment?
Thanks,
Andy

How do I combine -nodata and stim_times for 3dDeconvolve?
