Hi,
sill I got stuck to that matter, which is not clear to me yet: Having a single z-value (i.e. the maximum z of a higher level FEAT analysis, thresholded at maximum height/voxel level) I'm searching for a way to yield the corrected p-value corresponding to that particular z-value.
Sorry for having posted an imprecise question & thanks for considering this one!
Ciao,
Armin

sorry - you'll need to go via ttologp as ztop is for converting single numbers, not images! but if you only have z and not t you can just create a vars image with all 1s in - call the z image the cope/CBs image and set the DOF very high.....
Cheers.
