Hello,
I am trying to covary for Gender in mri_glmfit, but I am having errors pop up. I tried to follow Doug's suggesting in this post: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg12272.html but after modifying my Xg.dat file and rerunning mri_glmfit, it says: ERROR: matrix is ill-conditioned or badly scaled, condno = 1.53319e+07
I can run it using the --illcond flag, but then I get a bunch of: *** CEPHES ERROR: fdtrc domain error ***
Can anyone please give advice on how to covary for Gender in mri_glmfit (or qdec)?
As always, thank you for all of your great help!! Jeff Sadino
