Hi AFNI experts,

I want to compare the results after using TENT and CSPLIN to decide which function I should use for the final analysis. I've run 3dDeconvolve using TENT(0,16,9), and later, run another 3dDeconvolve using CSPLIN(0,16,9), for both instances, I used the same data (of 1 participant) and the same stim_times 1D files. I expected to see smoother HRFs when using CSPLIN, but surprisingly, when comparing, I got the exact same parameter estimates after running 3dROIstats. Is there an explanation for why I got the same betas after using 2 different functions? The experiment is the Monetary Incentive Delay task with a even-related design.

Thanks,
Tien
