Re: [Freesurfer] matrix is ill-conditioned or badly scaled, condno = 27492.1

[Douglas Greve]

Try multiplying the covariate by 100 (after subtracting the mean).

Re: [Freesurfer] matrix is ill-conditioned or badly scaled, condno = 27492.1

[Nabin Koirala]

I did that but it still does not work, it is almost the same error except
the condno is now 15521.8 before it was 27492.1, though I am not sure if
that tells something about the error. Could it be something else ?
Thank you.

Re: [Freesurfer] matrix is ill-conditioned or badly scaled, condno = 27492.1

[Douglas Greve]

I'm not sure what the difference is. Compute the mean of the 2nd column, 
then subtract that number from the values in the 2nd column.

[Freesurfer] matrix is ill-conditioned or badly scaled, condno = 27492.1

[Nabin Koirala]

Dear Freesurfer forum,

'I am trying to run qdec analysis for a group of subjects to see if
correlation exists but I am getting this error only for this  particular
set of data but could not figure out what is exactly wrong with it. Your
suggestion would be greatly appreciated.

Following is the terminal output for the process:
..
Saving design matrix to /g/f/h/s/freesurfer/subjects/qdec/Untitled/Xg.dat
Normalized matrix condition is 27492.1

ERROR: matrix is ill-conditioned or badly scaled, condno = 27492.1

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 /g/f/h/s/freesurfer/subjects/qdec/Untitled/y.mgh --fsgd
/g/f/h/s/freesurfer/subjects/qdec/Untitled/qdec.fsgd dods --glmdir
/g/f/h/s/freesurfer/subjects/qdec/Untitled --surf fsaverage lh --label
/g/f/h/s/freesurfer/subjects/fsaverage/label/lh.aparc.label --C
/g/f/h/s/freesurfer/subjects/qdec/Untitled/contrasts/lh-Avg-Intercept-thickness.mat
--C
/g/f/h/s/freesurfer/subjects/qdec/Untitled/contrasts/lh-Avg-thickness-alpha1-Cor.mat
  2. The FSGD file (if using one)
  3. And the design matrix above
Error in Analyze: command failed: mri_glmfit --y
/g/f/h/s/freesurfer/subjects/qdec/Untitled/y.mgh --fsgd

Many thanks in advance.
