I'm getting the following erorr when running Qdec "Analyze"

Model Factors:


Discrete (fixed factors)

 ADHD_Persist

  MJ_group

 Nuisance factor:

 Age


ERROR: matrix is ill-conditioned or badly scaled, condno = 10355.4
--------------------------------
Possible problem with experimental design:
Check for duplicate entries and/or lack of range of
continuous variables within a class.

If you seek help with this problem, make sure to send:
  1. Your command line:
    mri_glmfit --y /Studies/MTA/qdec/MTA_persistanceCD/y.mgh --fsgd 
/Studies/MTA/qdec/MTA_persistanceCD/qdec.fsgd dods --glmdir
