Hi there,

I included the the SPM/VBM grey matter output as a voxel-wise covariate in the ANOVA (3dMVM). After I ran the anova with the covariate, I didn't see any differences in the output relative to when no covariate was included. Below is the code I used. There were no error messages. Does this code look correct?

Thank you very much.
