Greetings AFNI experts:

I am performing group analyses using a 3dANOVA3 -type 5 model, with:

-alevels 2 for groups (males and females) and
-blevels 3 for task effect and
-clevels for individual subjects within a group.

Since I cannot use the "-xdiff" option I was wondering if I can include in -blevels contrasts of AUC: for example happy condition minus sad condition. This way I will not have to also do t-tests.

Also, another question whiles I am at it: I have converted all my f-stats to z scores which I am entering into the ANOVA. Thereafter I will perform an alphasim on the original datasets, and finally I shall convert my z scores back to p values. Please kindly advise if this is the correct way to proceed in order to get my experimental effects for groups.

Thank you,
Jasmin BS
