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
