Hello , I have results for my mri_glmfit-sim. I find a significant results in my cache.th20abs.sig.cluster.summary. Yet, the cluster size of the significant cluster is almost the size of the total cortical surface area. I am not sure what to make of this any help would be helpful.

Try raising the threshold

Hello I have tried using a greater threshold,(original 0.05) now 0.001 sill the result persist. Is there a way to threshold over a specific region?

You can do the analysis in a particular region with masking (--mask input to mri_glmfit). You can also load the uncorrected overlay into freeview and adjust the threshold until you get a cluster distribution you like, then use that threshold in mri_glmfit-sim
