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:

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

Greetings AFNI experts- I am having a bit of trouble running a 3dMVM script. When I run the following script:

3dMVM -prefix Fdb_Novel_Chosen_ZNB_ZIT_all_mod -jobs 7	\
-bsVars 'ZNB+ZIT'					\
-wsVars 'Condition' \
-qVars 'ZNB,ZIT' \
-mask Mask_TT_caez_colin27_T1_18_resample+tlrc.BRIK	\
-dataTable @datatable.txt

I get the following output from 3dMVM:

*+ WARNING: mri_fdrize: will not process only 0 values (min=20)
++ Smallest FDR q [0 (Intercept) F] = 0
*+ WARNING: mri_fdrize: will not process only 0 values (min=20)
++ Smallest FDR q [1 ZNB F] = 0
*+ WARNING: mri_fdrize: will not process only 0 values (min=20)
++ Smallest FDR q [2 ZIT F] = 0
*+ WARNING: mri_fdrize: will not process only 0 values (min=20)
++ Smallest FDR q [3 Condition F] = 0
*+ WARNING: mri_fdrize: will not process only 0 values (min=20)
++ Smallest FDR q [4 ZNB:Condition F] = 0
*+ WARNING: mri_fdrize: will not process only 0 values (min=20)
++ Smallest FDR q [5 ZIT:Condition F] = 0

Congratulations! You have got an output Fdb_Novel_Chosen_ZNB_ZIT_all_mod+tlrc.

2: In summary.Anova.mlm(object$Anova, multivariate = FALSE) :

When I open the brick and head files created by 3dMVM in the AFNI viewer they appear to be empty- wondering if anybody has gotten this error before when using 3dMVM and what folks have done to fix it? Thanks for your help!
