Hello everyone,
I have conducted an event-related fMRI. It's a 2x2 factorial study and I am
interested in the interaction.
In particular I would like to look at the interaction at the second level
statistics taking into account both the HRF and the temporal derivative.
If I use the factorial design at the first level of analysis -as explained in
chapt 27 for 'face data' in spm5 manual- I get the con* files for main effects
and interaction. Can I use then the interaction contrast file to make inference
at second level?
Thank you in advance,
Marzia
