External Email - Use Caution        

Hi there,
 
I tried to analysed "mri_glmfit --glmdir g1v7.wls --y ces.nii.gz --wls cesvar.nii.gz --C Main.mtx --C PDI.mtx --C Sex.mtx --C Age.mtx --C Edu.mtx --C BDI.mtx --C SBQ.mtx --C CD.mtx --fsgd g1v7.fsgd --surface fsaverage lh --cortex --fwhm 5 "
 
There were messages for error as follows: 
--------------------------------------------
Error: matrix is ill-conditioned or badly scaled, condno = 10649.3
-----------------------------------------------------------
 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.bin --glmdir g1v7.wls --y ces.nii.gz --wls cesvar.nii.gz --C Main.mtx --C PDI.mtx --C Sex.mtx --C Age.mtx --C Edu.mtx --C BDI.mtx --C SBQ.mtx --C CD.mtx --fsgd g1v7.fsgd --surface fsaverage lh --cortex --fwhm 5
  2. The FSGD file (if using one)
  3. And the design matrix above
Attempting to diagnose further
SumSq: Min=8.774964 (col 3), Max=724.138794 (col 8)
 The scale is much different between columns 3 and 8, you may want to
 normalize by subtracting the mean and dividing by the standard deviation.
 
 
What is the problem?
