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 doing a 2 (Group: dep & ctrl) x 2 (Time: Pre & Post) design with scanner a categorical covariate. I have copied the model I did below. If I also wanted to examine whether depprevpost was different than ctrlprevpost, how would I include that with the model I have provided below? Thank you!

3dMVM -prefix scanner -jobs 1 \
-mask minicolinmask+orig \
-bsVars "grp+scanner" \
-wsVars "time" \
-num_glt 5 \
-gltLabel 1 dep_v_ctrl_pre -gltCode 1 'grp : 1*dep -1*ctrl time : 1*pre' \
-gltLabel 2 dep_v_ctrl_post -gltCode 2 'grp : 1*dep -1*ctrl time : 1*post' \
-gltLabel 3 dep_pre_v_post -gltCode 3 'time : 1*pre -1*post grp : 1*dep' \
-gltLabel 4 ctrl_pre_v_post -gltCode 4 'time : 1*pre -1*post grp : 1*ctrl' \
-gltLabel 5 grp_time_interaction -gltCode 5 'grp : 1*dep -1*ctrl time : 1*pre -1*post' \
