It looks like you have created your fsgd file using a windows computer. Try running
cat file.fsgd | sed 's/\r/\n/g' > new.file.fsgd
probably have to do the same with the contrast matrix file

Hi Freesurfer group -
I am receiving errors each time I try to run mri_glmfit. It appears to be the way I set up either the fsgd or mtx file. Any assistance would be greatly appreciated. Thanks, Chaz
Hypothesis for the contrast in the mtx file: Is there an average affect of heat threshold regressing out the effect of gender and age? Command-line executed:
mri_glmfit --y lh.heatthreshold.thickness.10.mgh --fsgd heatthreshold.fsgd dods --C g1g2.heatthreshold.age.mtx --surf fsaverage lh --cortex --glmdir lh.gender.heatthreshold.age.glmdir
I seem to be getting 1 or 2 errors 1: gdfReadHeader: reading heatthreshold1.fsgd

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:
- Your command line:
mri_glmfit --y lh.heatthreshold.thickness.10.mgh --fsgd heatthreshold1.fsgd dods --C g1g2.heatthreshold.age.mtx --surf fsaverage lh --cortex --glmdir lh.gender.heatthreshold.age.glmdir
