Thank you so much, Rick. I really appreciate all your help! I'll reach out after I've run some individual levels and take a look at the output if anything looks odd.

I can take the duration modulation out of it if that's best, they're all the same duration so it shouldn't be an issue- that's just how we typically have modeled our stim files in the past.

Thank you, Rick!
Going off of this other help now that I have the "individual modulation" language...
I THINK I've gotten it coded up correctly if this looks good? THANK YOU SO MUCH!

Oh wow that's amazing! So much easier.
Just to clarify, I'll have a cue.1D file with 3 rows (because I have 3 runs) which I'll use the -stim_times_IM flag for
I'll also have a bunch of regressors of no interest (feedback epoch onsets)

Hello!
I'm trying to run some analyses that are conceptually similar to a PPI and parametric modulation. In a nutshell, I'm going to be using the trial-by-trial beta parameter from my anticipatory (cue) epoch as a parametric regressor for my feedback (FB) epoch. So the first step is to run individual level analyses to get the trial-by-trial coefficients for my cue epoch.
My task

Hello!
1) Yes, you are correct thank you! And thanks! I figured that more complex designs may lead to messier looking output but wanted to make sure. This is an event related design with many different things going on so I would expect it to be a bit less clear than in the example. And I do see visual cortex here which is comforting.
2) Here is the output from that command. I'd be ha

Hello!
Thank you so much for adding in this wonderful index.html function. I have two questions related to the output.
1) When I look in the va2t block, the background does not look nice and solidly black like it does in your example (https://afni.nimh.nih.gov/pub/dist/doc/htmldoc/tutorials/apqc_html/apqc_ex1.html) and there is some activation outside of the brain. However, I do see visual
