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

Hello,

Sorry if this is a duplicate. I tried posting but I don't see it. Anyway, I just wanted to solve one additional problem. I am interested in the Age main effect, specifically the direction of it. The F test is reported, but it doesn't provide the slope.

I assume I can run the following?

'DxGroup : 1*ADHD -1*Typical Age : '
'DxGroup : 1*ADHD Age : '
'DxGroup : 1*Typical Age : '

which will give me everything I want for Age? Age is centered on the mean.

Does this look right?
