If I'd like to show a contrast map between two group, which is the correct form? If I set offset=1 the red area will be more larger, with more results than offset=0, the the blue (negative) will be stable. If I apply the Montecarlo Sim the results will seem to be in accord to offset=0. Which is the true map? Thanks,

For example, I'm noting that if set +1 as offset the red statistical area is more larger.

So for example in the red/positive blue/negative one, the cross-over doesn't have to be at 0 cheers Bruce On Fri, 22 Mar 2013, std...@virgilio.it wrote: > Hi list, > I have a question, probably trivial, on OFFSET in qdec GUI.
