The problem is that all of your class=0 subjects have a 0 duration
meaning that you cannot compute a duration slope for this class. In this
special case, you can run a different-offset, same-slope analysis with
--fsgd dur.fsgd doss
Change your contrast matrix to 1 -1 0

correcting for disease duration.
I enclose here the fsgd file and the design matrix.
I've followed all the steps of the tutorial
