Dear AFNI Community,

So, I currently have an fMRI scan using a rapid adaptation paradigm in which pairs of stimuli are presented during a silent period following an acquisition. Each TR is 3.18s long and the delay is 1.5 so the TA is 1.68s.
I'm wondering how do I tell 3dDeconvolve that the scans are discontinuous, and if it is important to do so. Ultimately what I'd like to do is capture the peak of the bold response associated with each event type (same stimulus presented twice vs. two different stimuli presented).
I read somewhere on the listserve that one strategy was creating dummy trials and then censoring them, but that won't work here since the TA is not half of the TR. Any advice or previous posts that I may have missed would be very helpful. Thanks!

Best,

Sri
