Dear Guillaume,
My experimental design is very similar to Gustavo's (2-way ANOVA within subject), however I have a factor that was manipulated in different sessions (scans) on the same day. I want to implement the first option that Gustavo suggested, but in the SPM interface it is only possible to apply this on factors that are in the same session and not between sessions.
Is there a way to do a first level 2-way ANOVA on two factors that one is within session and the other is between? Or does it mean that my only option is to apply the second approach, and if so is that a valid option?
Thanks in advance,
Ayam Greental
