It is not necessarily wrong (though you will need to increase the number of iterations to may be 1000). To see all clusters regardless of significance, add --cwp 1. If you're cluster does not show up , then somethign is wrong.

Hello! I'm toying with some images acquired by following the dt_recon tutorial (fa-tal). I have prepared them for group analysis and run mri_glmfit, and the results look decent. However, I wanted to correct for multiple comparisons using for example
mri_glmfit-sim --sim mc-full 100 2 cdbasename --sim-sign abs -glmdir testdir --overwrite And variations of this command. None of them find any cluster, and the output file (cdbasename.sig.cluster.summary) always reports zero cluster, no matter how I change the thresh value. Am I doing something wrong?
