Dear Rene,
From looking at your other email it appears you are viewing the “raw” tstat images ( e.g. tbss_tstat1 ). You can restrict the voxels that are displayed by changing the display range in FSLeyes, however if you are interested in the results of randomise’s inference then the images to view are the <blah>_corrp_tstat? images which contain the ( 1-p ) values - again setting a minimum display value in FSLeyes ( say 0.95 ) can be useful here.
You can certainly use cluster after randomise ( e.g. ) to find clusters of significant voxels in the ( 1-p ) value images.
Kind Regards
Matthew
