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

Thank you Gang!

> Is the script + table correct for this experiment?

The following 3 lines

-gltCode 1 'Treatment: 1*real -1*sham' \
-gltCode 2 'Stim: 1*alc -1*non_alc' \
-gltCode 3 'Treatment: 1*real -1*sham Stim: 1*alc -1*non_alc' \

should be changed to (add a space before each colon)

-gltCode 1 'Treatment : 1*real -1*sham' \
-gltCode 2 'Stim : 1*alc -1*non_alc' \
-gltCode 3 'Treatment : 1*real -1*sham Stim : 1*alc -1*non_alc' \

This is from an old script that have worked without any errors or warnings. I have got the t-scores from the 3 -gltCodes. Would those results be faulty without the extra space before the colon?

> Meaning of AUQ1 F?

It's the main effect of AUQ1, which is the t-statistic value squared.

So the variance of the other factors are not taken into account? It's just the AUQ on its own?

> Why don't I get AUQ1:Treatment, but only get AUQ1:Stim?

Because you didn't ask for it. To get the interaction, try

-bsVars "Treatment*AUQ1" \

Thanks!

My script above: 
3dMVM -prefix covariates -dataTable @table_plus_covariates.txt -jobs 10 \
-mask mask+tlrc \
-bsVars "Treatment+AUQ1" \
-qVars "AUQ1" \
-wsVars Stim \
.... + glt

Gave me the interaction with "stim" without me explicitly telling it to? I just put in "Treatment+AUQ1" and defined my qVar as "AUQ1". Also is it * or +? What is the difference? Should I change the + to a * or add another line?
