I would like to plot the contrast estimate and 90% C.I. for the areas that activated for a contrast of interest.
For anova, our lab created and used a f-contrast to plot the contrast estimate (which shows the effect size for each condition for coordinates at activation).
I do not know which contrast that I need to create which can be used to plot the contrast estimate. In other words, what contrast should I put when the SPM interface asks me after choosing to 'plot' and then 'Contrast estimates and 90% C.I.'...My aim is to look at the effect size for each condition for each group (compared to the 'baseline').
It was a two samples t test done. I have attached the graphics that may help.
Hope my explanations are clear...
