Open the Glm GUI.
Choose the higher-level design.
Set the number of inputs to the total number of subjects.
Select the Wizard.
Choose two groups, unpaired.
Set the number of subjects in the first group.
Check the image looks OK.
Go back to the original (small) window.
Choose the appropriate directory.
Type in a filename.
And that's it.
All the best,

The manual says that I should use the glm in the FSL program with 1 EV and the matrix should be 0 for one group and 1 for the other. I tried to create the matrix by changing the number of inputs but then I canīt save it.
