Hello,

I recently ran a very basic, one group ISC analysis on my data (58 subjects). I got the following warning:

*+ WARNING: Smallest FDR q [0  t] = 0.9999 ==> few true single voxel detections
++ Smallest FDR q [1 #1] = 4.36105e-13

I am a little confused as to what this means. What are the [0 t] and the [1 #1] referring to? When I am looking at the images in AFNI the q value stays at 0.999 no matter where I set the overlay slider, which is concerning!

Thanks!
