I'm using Normis for analysis, but I'm having trouble saving the results. I'm not sure how to fix this, so I'm asking. The error message is "Normative data for aseg_bigregions.csv, aseg.csv, brainstem.csv, lhpcsub.csv, rh.aparc.csv, etc...were not saved." I think there's a problem with Normal modeling. How can I fix this?
