Hey Bruce,

Yes, that directory exists, as I said if I only choose groups(high stress
and low stress) as the discrete variables its runs fine and analyses, it
only shows the error if I add more factors (like gender) into the software.

My subjects directory is set to
export SUBJECTS_DIR=/tallaght-disk4/IMAGEN/Saloni_data/freesurfer_output/

and yes I have run recon-all-qcache on all my subjects.
