Hi experts,
I am setting up an F-test for 3 groups in TBSS...just looking for any differences.
I have 3EVs: Group 1, Group 2, and Group3.
My contrast matrix is simple:
Group 1: 1 0 0
Group 2: 0 1 0
Group 3: 0 0 1
I have looked through the archives, and it looks like my design.fts file for the F-Test should look like:
1 1 1
But when I tried that in the GLM gui, it gave me an error message and said it was not a valid F-test.
What should the design.fts file look like?
Many thanks!
