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,
I am using 3dmvm to look at main effects and interaction for 3 factors : group, age and sex with resting state data. I also need to look at correlation of a behavioural data with resting states I wonder if the following GLTs are correct :
glt1: correlation of behav1 difference between con and pat , controlling for age and sex?
glt2: correlation of behav1 with con , controlling for age and sex ?
glt3: main effect of group controlling for age and sex?

3dMVM -prefix mvm_group_age_sex_behav1 -jobs 4 \
-bsVars "group*age*sex*behav1" \
-qVars behav1 \
-num_glt 3 \
-gltLabel 1 con_vs_pat_behav1 -gltCode 1 'group : 1*con -1*pat behav1:' \
-gltLabel 2 con_corr_behav1 -gltCode 2 'group : 1*con behav1:'' \
-gltLabel 3 group_main -gltCode 3 'group : 1*con -1*pat' \
-dataTable \
Subj group age sex behav1 InputFile \
subj001 con old female 1.4 subj001_ses-01_rs.nii \
subj002 pat old female 1 subj002_ses-01_rs.nii \
