Hi Doug,
Thanks for the new fsgd file - it solved the error. However, now I get a different error:
ERROR: dimension mismatch between y and X. y has 46 inputs, X has 71 rows.
which is similar to the error I got when I tried to do this analysis in QDEC. I've attached my Xg.dat. I'm not sure what it's supposed to look like. I want to compare the three groups while regressing out age.
Thank you!

The fsgd file appears to have been created using a windows program (or mac program that saves in windows format). Is that correct? I've attached a linux-compatible version. Let me know if that works. doug

Hello,
I would like to conduct an analysis using mri_glmfit but I'm getting this error: ERROR: matrix is ill-conditioned or badly scaled, condno = 1e+08
My command was: mri_glmfit --y lh.area.fwhm10.fsaverage.mgh --fsgd finalgroupanalysis.fsgd dods --C group_effect.mtx --surf fsaverage lh --cortex --glmdir lh.surfacearea.glmdir
My FSGD file is attached. It contains 3 classes and 1 variable (age).
And my design matrix is 1 -1 0 0 0 0 1 0 -1 0 0 0
Please help!
Thank you for your time, Wanda
