Hi,

I was wondering if my 3dLME model is correct. I am trying to look at changes in myelination from session 1 to 3, while controlling for age and gender effects. I only have one group, so no between-subjects factors.

Thanks.

module load AFNI
module load R/3.2.0-goolf-1.7.20

3dLME -prefix /path_to_dir/myelin_gm-masked.nii \
-mask /path_to_mask/gm_mask_v2.nii \
