Hello, i am having problems accessing the 3D surfaces of my data. Is there any advice you could provide for me please?

bash-4.1$ freeview -f \
> /projects/pbic1030/Michael/subjects/Subj1/fsaverage/surf/lh.pial:annot=aparc.annot:name=pial_aparc:visible=0 \
> /projects/pbic1030/Michael/subjects/Subj1/fsaverage/surf/lh.inflated:overlay=lh.thickness:overlay_threshold=0.1,3::name=inflated_thickness:visible=0 \
> /projects/pbic1030/Michael/subjects/Subj1/fsaverage/surf/lh.inflated:visible=0 \
> /projects/pbic1030/Michael/subjects/Subj1/fsaverage/surf/lh.white:visible=0 \
> /projects/pbic1030/Michael/subjects/Subj1/fsaverage/surf/lh.pial \
> --viewport 3d
bash: freeview: command not found

Kind regards, Michael
