Dear FSL expert,
I have a question for you. I have never used ANOVA in Randomise by also using the F-test. The problem is that I have always errors.
My example is:
I have three group (A B C) and 10 subjects. Moreover, I also have age and disability score as covariates
My design.mat is this:
A B C age score
1 0 0 23 5
1 0 0 22 5
1 0 0 55 1
1 0 0 33 2
0 1 0 24 2
0 1 0 43 1
0 1 0 41 2
0 0 1 23 0
0 0 1 22 1
0 0 1 55 1
In theory, it should be correct. Right?
My design.com is:
1 -1 0 0 0 (A>B)
1 0 -1 0 0 (A>C)
0 1 -1 0 0 (B>C)
Is it correct?
Then, I have problem to create the design.fts.
I created it in this way:
1 1 1
is it correct? because I also have errors:
An exception has been thrown
Error: This (f)contrast appears to be rank defficient, please check your design.
Do I also need the grp file?
Thanks in advance for your help.
Mike.
