I also tried the LME without any covariates, with and without the + sign with the model below and the contrasts remain the same, contrast 4 is the same as contrast 3. If I run this same contrast with GroupAna, the contrast is correct. Any advice on how to get these contrasts to work with the LME?
3dLME -prefix LME_GlucCntlvsGlucSal_GrpxSessxTask_n34 -jobs 2 \
-mask /data1/temp_space/lacadie/ref3d/MNI/MNI_T1_3mm_mask.nii.gz \
-model 'Session*Task*Group' \
-SS_type 1 \
-ranEff '~1'
-num_glt 6
-gltLabel 1 'HF-NF' -gltCode 1 'Task : 1*HiFat -1*NonFood ' \
-gltLabel 2 'LF-NF' -gltCode 2 'Task : 1*LowFat -1*NonFood ' \
-gltLabel 3 'HF-LF' -gltCode 3 'Task : 1*HiFat -1*LowFat ' \
-gltLabel 4 'AllFood-NF' -gltCode 4 'Task : 0.5*HiFat 0.5*LowFat -1*NonFood' \
-gltLabel 5 'Eugly_AllFood-NF' -gltCode 5 'Task : 0.5*HiFat 0.5*LowFat -1*NonFood Group : 1*Eugly' \
-gltLabel 6 'Sal_AllFood-NF' -gltCode 6 'Task : 0.5*HiFat +0.5*LowFat -1*NonFood Group : 1*Saline' \
