Hi all,

I need to do linear mixed-effects (LME) modeling analysis of two within-subject factors in AFNI.
Factor1 has two levels: level1OfFactor1, level2OfFactor1.
And Factor2 has three levels : level1OfFactor2,level2OfFactor2, level3OfFactor2.
There are no demos of two within-subject factors in the help files.So I wrote my analysis script by rewriting the demo of one within-subject factor and one between-subject factor in the help file of 3dLME.Maybe there is some difference between 'one between-subject &one within-subject factors' and 'two within-subject factors' in the analysis code that I didn't know .An error came out when my script processed the 28th slice.

The feedback of error is:

Can you tell me what's wrong with my script and how to improve it?
Thank you!
