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

Hi AFNI gurus,

I cannot get 3dMVM running using two covariates - I am sure I am doing something wrong. I think the problem stems from attempting to use two covariates in the gltCode - can such a thing be done? I've tried both glt and glfCode. I realize that my gltCode tests are t-tests which could be done with 3dttest++, but I have many such tests to run and was trying to not conduct too many t-tests.

I'd appreciate any input.
-n

Command I'm attempting to run: 
3dMVM -prefix MVM_FUMC_10 -jobs 10 -mask Intersection_GM_mask+tlrc \
-bsVars 'Group*Snif+Group*SPA' \
-wsVars Stim \
-qVars 'Snif,SPA' \
-num_glt 4 \
-gltLabel 1 G_Mask -gltCode 1 'Group : 1*Con -1*Aut Stim : 1*Mask Snif : SPA : ' \
-gltLabel 2 G_FBO -gltCode 2 'Group : 1*Con -1*Aut Stim : 1*FBO Snif : SPA : ' \
-gltLabel 3 G_UBO -gltCode 3 'Group : 1*Con -1*Aut Stim : 1*UBO Snif : SPA : ' \
-gltLabel 4 G_CA -gltCode 4 'Group : 1*Con -1*Aut Stim : 1*CA Snif : SPA : '  \
