I can't figure out what's happening, so I'll probably need the data. Can
you tar up the input data, the fsgd, and the contrast matrices and drop
them for me at: www.nmr.mgh.harvard.edu/facility/filedrop?

Dear freesurfer users
I got an error message during mri_glmfit. (please see below my error
message)
I was able to find 'mri_glmfit.log' file in './glm/lh.dx_age.glmdir'
directory
Thank you for advance
---------------------------------------------------
These are my constrasts.
: to construct the contrast vector for testing volume change according
to age = age.mat
0 0 0 1
: for effect of interest (ANOVA: f test) -> Am I right?
1 0 0 0
0 1 0 0
0 0 1 0
: for difference btw 3 group independent of age -> Am I right?
-1 0 1 0
0 -1 1 0
There are three class and one variable (see below my FSGD file)
# FSGD file
GroupDescriptorFile 1
Title Thickness vs Dx and Age
Class A circle blue
Class B circle green
Class C plus red
Variables Age
Input 61 A 71
Input 54 A 72
Input 12 B 74
Input 33 B 77
Input 63 C 80
Input 01 C 87
