Hi Frank,

I'm running the differential tractography using the CLI at the latest version, following the command line as below. But the "--demo" is not used/recognized". Could you please check whether the option "--demo" or "--select" is being removed from the 'Hou' version? Thanks!

${cli} --action=trk --source=${Path}/rec/gqi/${ID}.fz --other_slices=${Path}/rec/qsdr/db/C.${index}.db.fz.m
od.db.fz --dt_metric1=C.${index}.db.fz.mod --dt_metric2=${index} --demo=demographic_als.txt --select="Age=${Age},Ge
nder=${Gender},Education=${Education}" --seed_count=1000000 --tip_iteration=16 --min_length=30 --dt_threshold_type=
2 --output=${Path}/differential/${index}/threshold_${thr}/hc-als_als/${ID}.tt.gz --recognize=${Path}/differential/$
{index}/threshold_${thr}/hc-als_als/${ID}.cluster --dt_threshold=${thr}

Please update DSI Studio and also do the following:

1. C.${index}.db.fz.mod in [Step C2 View/Edit Database] and use the
File menu to load demographic_als.txt and save it. I assume that
demographic_als.txt should only have Age, Gender, and Education
2. in the command line, replace --select by
--subject_demo="${Age},${Gender},${Education}"
3. Check the command line output to see if DSI Studio correctly use
the information.

Best regards,
Frank
