> if i want to talk about significance in my case, what would be the best way of doing so?

I don't remember whether 3dfim+ outputs t-stat for each regressor. If it does not, you can use the link Paul provided before to get the t-stat (https://afni.nimh.nih.gov/sscc/gangc/tr.html). However, it would be more preferred to just use 3dDeconvolve instead of 3dfim+ for that purpose.
