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!
