Choosing a control group for Dunnett's post-hoc test

Troubleshooting


Problem

I am trying to run a Dunnett's post-hoc test after a one way ANOVA. I have 7 groups and want to choose one of them as the control (against which all other groups will be compared). The Dunnett test option in the Post-Hoc dialog of the One-Way ANOVA procedure seems to allow either the first or the last group to be selected as the Control Category. However, neither of these groups is my choice for the control category. Is there a way that I can designate some other group? Do I need to recode the factor or enter the data so that the desired control category appears first or last in the file?
