Hi Douglas,

Thanks for looking at this. I am using FS 5.3 on a Mac OS 10.9 (Mavericks). If that helps, I wrote the initial file with TextWrangler.

I cannot replicate. What version of FS are you using and what platform are you on?

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
