Dear list
My question was asked in 1998 and at the time Karl stated that the
contrasts had to come from the same statistical model. Is this still the
case ?

The contrasts have to come from the same statistical model (i.e.
analysis). This is not a mathematical requirement but is required by
the data reduction [to a point list] employed by SPM.
