Maybe my understanding of how to use FDR correction is incorrect, but I ran a one-sample t-test using the tstat brick of each subject's 3ddeconvolve bucket dataset as my input. 3dttest said it created 1 FDR curves in header, but when I open the results in AFNI, I couldn't see the q values. So then I ran the command "3drefit -addFDR" on the output dataset, but there appears to be an error. Upon moving the threshold slider bar, my q values decrease to some value (i.e. 0.0879) and then don't get any smaller no matter how far up I move the slider bar (even if I set it to power-of-10 = 3 and put it at the every top). Are my commands wrong, or am I implementing the FDR correction incorrectly?

Thanks,
Michael
