AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

One last question.
I am doing a one-way ANOVA with three independent groups (HCC, LCC, and SZ). All I want to know is what are the omnibus differences among the three groups, but I want to do this while "controling/adjusting " for the effect of Age.

Do I need to specify this in a glt code?

If so, is this correct?

-gltLabel 1 GROUP -gltCode 1 'Grp : 1*HCC -1*LCC -2*SZ Age : '

I'm not really clear what -2 multiplied by the SZ group means but I can't figure out how else to put all three groups in the comparison.
Thanks!
