Hi. I'm trying to determine voxel-level correlation between 2 image types using 3dtest++ with voxel-level covariate. Both image types are in 2mm MNI space. The program crashes with no useful information (for me). What's wrong?

Here is the script:

SUVdir=/autofs/cluster/stroke/PSF/PET/SUV
MRdir=/autofs/cluster/stroke/PSF/MR

mkdir -p $SUVdir/ttests_covar/P8_suvr-gfa_3dttest
outdir=$SUVdir/ttests_covar/P8_suvr-gfa_3dttest

cd $SUVdir/SUVR-wb_nl_MNI

3dttest++ \
-prefix $outdir/P8_suvr-gfa \
-DAFNI_DEBUG_TABLE=YES \
-setA \
PSF_001.nii.gz \
PSF_002.nii.gz \
PSF_003.nii.gz \
PSF_005.nii.gz \
PSF_006.nii.gz \
PSF_008.nii.gz \
PSF_009.nii.gz \
PSF_010.nii.gz \
-mask $MRdir/composite_lesion/MNI152_T1_2mm_brain_no-LV-Lesion_bin.nii.gz \
-covariates /autofs/cluster/stroke/PSF/scripts/covarfile_gfa

Here is the covariate file - covarfile_gfa:
subj GFA
PSF_001 /autofs/cluster/stroke/PSF/PET/SUV/SUVR-wb_nl_MNI/PSF_001_gfa.nii.gz

PSF_006 /autofs/cluster/stroke/PSF/PET/SUV/SUVR-wb_nl_MNI/PSF_006_gfa.nii.gz
