When I run Three Groups (One Factor/Three Levels), three Covariates,my MTX is
1 -1 0 0 0 0 0 0 0 0 0 0
1 0 -1 0 0 0 0 0 0 0 0 0
It’s wrong,What should I do
--------------------------------
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 rh_teach66.mgh --fsgd glmteach66.fsgd --C glmteach66.mtx
--glmdir group66.area_66sm.rh --fwhm 10 --surface fsaverage rh --eres-save
2. The terminal output of this program (ie, everything it prints to the
screen)
3. The FSGD file (glmteach66.fsgd)
4. The design matrix group66.area_66sm.rh/Xg.dat
Attempting to diagnose further
WARNING: Class d has 4 members. With 3 variables and using DODS, This is the
bare minimum which may cause problems with the design matrix.
WARNING: Class m has 4 members. With 3 variables and using DODS, This is the
bare minimum which may cause problems with the design matrix.
WARNING: Class h has 4 members. With 3 variables and using DODS, This is the
bare minimum which may cause problems with the design matrix.
