Dear AFNI experts,
I have an experiment, which is modeled after this paper.
I'm interested in measuring repetition suppression across conditions with HRF estimation, where each event (two brief picture presentations) lasts for 1 sec with 2-4 sec of ITI (TR = 1 sec). There are 20 trials per condition within each run.
This particular paper used FSL, and they stated they used a double-gamma function, but would it make more sense to use the tent (tentzero) function with 3dDeconvolve when using AFNI (compared to the double-gamma option)?
Unlike this paper, my experiment is not TR-locked.
I'm also curious about your opinion on using GLMsingle versus TENTzero for this paradigm if you have experience with both.
