Hi all,

I am trying to run a basic ANOVA using 3dMVM. When I attempt to run the script, I get an accurate summary of data structure, however, the script 'errors out' after reading the input files. My error is as follows:

Reading input files now...

~~~~~~~~~~~~~~~~~~~ Model test failed! ~~~~~~~~~~~~~~~~~~~
Possible reasons:

0) Make sure that R packages afex and phia have been installed. See the 3dMVM
help documentation for more details.
1) Inappropriate model specification with options -model, -wsVars, or -qVars.
Note that within-subject or repeated-measures variables have to be declared
with -wsVars.

2) Misspecifications in general linear test coding with -gltCode.

3) Mistakes in data table. Check the data structure shown above, and verify
whether there are any inconsistencies.

4) Not enough number of subjects. This may happen when there are two or more
withi-subject factors. For example, a model with two within-subject factors with
m and n levels respectively requires more than (m-1)*(n-1) subjects to be able to
model the two-way interaction with the multivariate approach.


** Error:
Quitting due to model test failure...

I am using R version 3.2.5 and I have all the listed packages installed and updated.

My script:
