I have 2 data sets I want to compare and analyze for differences in
activation. I'll call them task 1 and task 2. When I enter task 1 as
the "A" (control) data set and task 2 as the "B" (Test) set, I get a
different answer than whe I enter task 2 as "A" and task 1 as "B", as
displayed by the picts in the report. It seems as if the results are only
showing positive Z values. I tried to enter a negative Z for the min value
but couldn't. I also tried the auto-scale Z score option and that made no
difference. Is there a way to display negative Z values as well? Or am I
thinking about this all wrong?
