Dear AFNI experts,

I have a question regarding afni's statistical tools:
I have three beta maps per subject corresponding to three condition, I want to know if at least in one condition I have a beta value above 0. Which corresponds to a contrast matrix equal to diag(3) (H0: Level1=Level2=Level3=0).
I used 3dMVM with -glfLabel 1 level_ftest -glfCode 1 'level : 1*level_1 & 1*level_3 & 1*level_5' but I'm not sure about that.

Did I do my statistical test correctly or not? Can I use the 3dANOVAx suite?

Thank you,
Roberto
