I have 12 subjects I am running 3dttest++ on. When I have all 12 participants, I get the error: "ERROR: Option -setA: ends prematurely after option ___ last participant here ____".

When I remove one particular participant, the error goes away. If I add that participant back, in any order, I get the prematurely ending error again. I am sure there is no typo, and that the participant and their model exists.

Any suggestions?
