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, I am trying to run an ANOVA with three groups and want to covary for age. I understand that if no qVars option is given, the default is to center age across the whole sample, however I want to center age within each group. I know the help document says to do this myself and then put it in the datatable, but my question is will the command then try to center it again since there is no option to "turn off" centering or will it recognize that the variables are centered. Thanks!
Amanda
