The "Times" field is for specific times from an iresp file. I used sine basis functions in 3dDeconvolve. The original iresp files are 3D+time, with 13 time points, which I separated into individual bricks with 3dcalc.
I was planning to test the group difference in terms of the HRF shape, not just the overall curve area. I'm not sure how to specify in model.txt. If there is another way that I could test the group difference, please let me know.
For brevity, I did not paste in my entire model.txt file. I actually have 13 subjects in the "alc" group and 5 controls.
Thank you.
