Hi,
I have read the Freesurfer Tutorial, but there is still something I do not understand.
I want to run the mri_glmfit-sim command on our data. I have one sample (10 subjects), which were examined at 2 different timepoints.
I tried to use this command:
mri_glmfit-sim --glmdir Plast_injury_Thickness_LH_sensorimotor.glmdir --sim mc-z 1000 2 lh_mz-z.abs --sim-sign abs --overwrite
The following error message occured:
y has 10 inputs, X has 20 Rows.
Although the X-file has only 10 rows (here is the content of the X file an y file)
X.mat =
1 1 1 1 1 1 1 1 1 1
y.fsgd =
GroupDescriptorFile 1 Title InjuryInducedChanges

What is exactly wrong? Or how do I apply the mri_glmfit-sim for longitudinal data correctly.
Thanks a lot for your help.
Best regards,
