Dear AFNI experts,

I'm trying to use the 'TENT' function in 3dDeconvolve to fit my data. In my experiment, the trial length was always 18s, but the inter-trial-interval (ITI) varied in 4, 6, 8, or 10s. In this case, should I just model the 18s; or should I take the varied ITI into account? Also, since there's still stimulus-driven activity during the ITI, I was just wondering if I want to model the ITIs as well, how should I set the 'TENT' function (i.e. what should be the starting and ending times in the 'TENT' function)?

Thanks for your help in advance!


Best,
Qing
