I'm not sure what you are doing here. You say that you have two continuous variables, but there is only one in the fsgd file. The contrast has 3 items, but it would test for the offset, not the slope. Also, why do you have --no-prune?

This is my matrix: 1 0 0
And my fsgd file:

This is the result: [cid:part1.9EE9F34D.23B9DFF4@mgh.harvard.edu][cid:part2.A1889CBE.3AAE2CA4@mgh.harvard.edu]
Am I proceeding correctly?
Thank you, Valeria
