Dear FSL users,
I'm quite new to FSL and I stumbled upon a problem that I can not seem to figure out. I'm doing an analysis with three groups, let's say A, B and C. Over these three groups I want to do an F-test. In the same analysis I want to do a between-group analysis. So my matrix looks like this:
A 1 0 0
B 0 1 0
C 0 0 1
A>B 1 -1 0
A>C 1 0 -1
B>A -1 1 0
B>C 0 1 -1
C>A -1 0 1
C>B 0 -1 1
Now my question is this: are these t-contrasts t-tests or post-hoc tests? Since if these are t-tests, I probably would have to correct the p-value and if they are post-hoc tests the p-value would already have been corrected right?
