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

For a long time the lack of 2nd-order contrast testing in 3dANOVA3 has largely prevented people from using the group analysis program for 2-way within-subject / repeated-measures ANOVA (3dANOVA3 -type 4) and 2-way mixed-effects ANOVA (3dANOVA3 -type 5). That is no longer the case. We recently added two new options in 3dANOVA3, -aBcontr and -Abcontr, for types 4 and 5 with the following usage:

-aBcontr c_1 c_2...c_a : j contrast_label -- 2nd order contrast in factor A, at fixed B level j

-Abcontr i : c_1 c_2...c_b contrast_label -- 2nd order contrast in factor B, at fixed A level i

We also modified options -amean, -bmean, -adiff, -bdiff, -acontr and -bcontr in 3dANOVA3 based on the same modification principles announced almost one month ago:

<[afni.nimh.nih.gov];

The newly released AFNI package will reflect the above modifications, and the relevant statistics will be provided in a new version of 3dANOVA2 and 3dANOVA3 manuals in the near future.
