Hello I keep getting the same error and am not sure how to address the issue.

I have attached the design matrix and the FSGD file and contrast file of interest

Thanks for the help

ERROR: matrix is ill-conditioned or badly scaled, condno = 1e+08
--------------------------------
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 STATS/lh.DEV_DIA_SEX.thickness.mgh --fsgd STATS/DEV_DIA_SEX.fsgd dods --C STATS/mainDEV.mat --surf fsaverage lh --cortex --glmdir STATS/lh.DEV_DIA_SEX.thickness.glmdir
  2. The FSGD file (if using one)
  3. And the design matrix above
