Condition slopes in PPI
analysis
Dear SPMers,
We are getting an interesting result with PPI
analysis suggesting that the slope of the relationship between
amygdala and PFC is greater in condition A than condition B. To
properly interpret the result, we would really like to know, for each
subject, what the slope of the relationship is separately for
Condition A and for Condition B, the difference of which forms the PPI
term. Does anyone know how to do this?
Thanks.
