Dear group, I now have error loading my qdec table into qdec, for this error

fsid column:        1
Number of factors:  8
Number of subjects: 168
ERROR: QdecSubject::GetContinuousFactor failure: could not find factor name: age_demeaned for subject XXX

However those 5 of those "factors" are continious, and Im assuming the problem is that for some reason qdec thinks they are categorical, and should have a file with levels corresponding to them. How I make freesurfer know they are continuous?

Kind Wishes,

Linn
