Dear FSL users,
I have three groups A, B and C; there are also two co variants (CV1 and CV2). At first step I did pairwise t-test between the groups in TBSS runs by using this contrast file
design.con
EV1(A) EV2(B) EV3(C) CV1 CV2
1 -1 0 0 0
-1 1 0 0 0
0 -1 1 0 0
0 1 -1 0 0
1 0 -1 0 0
-1 0 1 0 0
Now I want to perform F-test followed by pairwise t-test.
How do I construct my fts file like "design.fts" and contrast file like "design.con" to achieve this ????
Which statistical procedure is more robust just doing individual t-test as I did eariler or doing F-test followed by pairwise t-test?
It would be nice if I could get some feedback on this issue
