Dear AFNI experts,

Hope you all are staying safe. I downloaded unprocessed resting-state data from the Human Connectome project where they had 4 scans for each participant (Session 1 L to R, Session 1 R to L, Session 2 L to R, Session 2 R to L). These 4 epi data were concatenated using 3dTcat and submitted to the proc py script like below.

afni_proc.py \
-blocks despike align tlrc volreg blur mask regress \

tcsh -xef py_result_"$subj"_script |& tee output.py_result_"$subj"_script

@ linenum++
end


In the middle of the proc py, I just had an error that I have never seen before (below).

** FATAL ERROR: -polort value can't be over 20

Could you please let me know what caused this issue and how to solve this?

Best,
JW
