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

Hi Adam,

If you wish to do an ANCOVA, you might find 3dttest++ or 3dMVM easier.

If you are absolutely determined to use 3dRegAna, you will need to "dummy code" your task variable. You can see Example 4 in the 3dRegAna white paper for guidance. If you have repeated-measures (i.e. everyone in the experiment did all 4 tasks) then things get even more interesting...

It's also possible that I missed your question, so feel free to clarify if so.
