Hi there FreeSurfer

When trying the GLM-analysis I keep getting the following error. Could you help me with fixing it?

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 lh.whiplash.thickness.10B.mgh --fsgd whiplash.fsgd dods --C group_diff.mtx --surf fsaverage lh --cortex --glmdir lh.whiplash.glmdir 
  2. The FSGD file (if using one)
  3. And the design matrix above

Thank you in advance,


Robby
