Hello!
Hoping someone can help, I am new to SPM and am trying to utilize a full factorial design to test the effects of a treatment, using a go nogo task.
I am using SPM5. I have 2 groups and two time points; I want to look at the nogo minus go contrast taking into account the effect of time, group and the group*time interaction.
Can someone please help clarify what needs to get entered into the design and which of the automatic contrasts produced by SPM that I should be looking at.
Thanks!
