Hello
I'm trying to perform my first PPI analysis.
In my block experiment I have two conditions (let's call them A and B) and the Rest.
First, as far as I understand I need to combine all my EV files from my block experiment into one file, is that right?
Then, what I'm interested in, is that I want to:
"show that my ROI interacts with some areas more in condition A than condition B (rather than just showing interaction is greater in condition A than baseline). How do I do that?" http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/PPIFAQ
Unfortunately, I don't understand how should the contrasts look like for
- showing that interaction is greater in A than baseline
- showing that interaction is greater in A than in B.
Could you please tell me how should I set contrast for these?
I will be very grateful for any help.
Best
Piotr
