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

Is your factor A a between-subjects factor like groups ASD andTD? If so, you should use 3dANOVA3 -type 5 ... -clevels 4, and change the coding for the second group as follows:

-dset 2 1 1 'td01.LOC.4runs.GLM+tlrc[4]' \
-dset 2 2 1 'td01.LOC.4runs.GLM+tlrc[37]' \
-dset 2 1 2 'td02.LOC.4runs.GLM+tlrc[4]' \
-dset 2 2 2 'td02.LOC.4runs.GLM+tlrc[37]' \
-dset 2 1 3 'td03.LOC.4runs.GLM+tlrc[4]' \
-dset 2 2 3 'td03.LOC.4runs.GLM+tlrc[37]' \
-dset 2 1 4 'td04.LOC.4runs.GLM+tlrc[4]' \
-dset 2 2 4 'td04.LOC.4runs.GLM+tlrc[37]' \

But then with only four subjects in each group you most likely would have power problem: not enough power to identify activation regions. If you do have 8 subjects per group, you would need to add more subjects in the script.
