Hi AFNI experts,

I'm hoping to use 3dMVM to conduct a 2x2x2 ANOVA with unequal subjects across two between-subjects conditions. The between subjects factor is Suicide Attempt History: Yes vs No. The within subjects factors are two experimental manipulations: emotional valence of experimental stimuli (Negative v. Neutral) and Attention Shifting (trials requiring attention shift v. repeat trials focusing on the same target). Using the code and data table format below, I'm getting an error message: "Inappropriate coding in test No.1! " In GLT 1, I'm hoping to find the difference between activation for negative (v. neutral) images specific to repeat trials for suicide attempters only. Any leads as to what I need to change would be greatly appreciated! Many thanks in advance.

Excerpt from the Data table:
(two notes: 1) I can't make the tabs display properly in this copy, but they do appear ok in the actual text file; 2) I deliberately posted age here as a 3-digit number to deidentify the data)
