Hi - yes you have to create that from the tstat, e.g.

fslmaths <tstat> -mul 0 -add 1 grot

ttoz grot <tstat> <dof>

where you need to get the <dof> (degrees of freedom) from your model.

Cheers.

Thanks, Steve.

Are the next three columns in the output the x y z coordinates of the peak voxel in each cluster? How can I get z stats of peak voxel?

By putting in a zstat image for the "cope" option instead of the tstat.

But, I see only tstat image, no zstat image of outputs of "randomise".

Best
