Dear all,

I am sure it is something obvious, but I am stuck with that error.
I am trying to analyse data and prepared my fsgd file, but when trying to use mri_glmfit, Terminal returns me the error

gdfReadHeader: reading group_age_sex.fsgd

ERROR: gdfRead: group_age_sex.fsgd is not formatted properly.

  The first string is 'GroupDescriptorFile', should be 'GroupDescriptorFile'


As you can read, I did not misspelled the GroupDescriptorFile and even added a 1 after! (as GroupDescriptorFile 1), as mentioned in the wiki.

It does not seem to be any “useless" tab in the fsgd file. I have attached an exemple (I just left 1 subject)


Thanks for your time.


Yann
