Thanks! I have check my contrasts and noticed that the wrong ones have
only negative values (e.g. only a single -1; the rest values are zeros).
So that might have been the problem, for it is a VBM-analysis. I removed
those.

> If you remove the "bad" contrast and all the previous contrasts from the design.con you can rerun randomise ( change the output filename! ) to obtain the final contrast outputs. Note that this second set of contrasts will be numbered from 1, so you will need to re-number the output images to match your original design.con.
