Hi Gang,
I know this is an old thread now, but just wondering if there were updates on this front.
Particularly, I am have a dataset where I have 3dAutomask-ed each individual's image to remove dropout regions. I was hoping to have this excluded person/voxel-wise in the group-level 3dLME - but it seems like it may be reading this in as zero values. I tried using the -bounds options but am getting an error (tested this a few ways but was aiming to use a lower bound of ~0.1 to remove any zeros where all valid values are positive in this case).

Example Script:
3dLMEr -prefix lme \
-jobs 4 -bounds .01 10 \
-mask MNI152_T1_2mm_brain_mask.nii \
-model 'Dx+Sex+age+(1|run)' \
-qVars 'age' -qVarCenters '0,' \
-gltCode ocd 'Dx : 1*OCD -1*Healthy' \
-dataTable @covars.txt
