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 ...... DefaultVariable Age
