Good morning AFNI experts - thanks in advance for some more help.
I have been running afni_proc.py for preprocessing of resting state analysis. Two of my subjects are coming back with this error, and I am not sure how to interpret it.
*+ WARNING: !! in Signal+Baseline matrix:

* Implies strong collinearity in the matrix columns!

the afni_proc settings (in case needed) are:
