[user@localhost temp]$ randomise -i L_Hipp_vertexMNI.nii.gz -m L_Hipp_vertexMNI_mask.nii.gz -o L_Hipp_vertexMNI_rand -d design.mat -t design.con -T 2
This will generate a number of files, one for each contrast (I think!). There are maps of t statistics, p values, and corrected p values, presumeably of regions that are significantly different based on the threshold (t statistic = 2 in the above example).
