contrasting parametric modulators
Hi,
I'm running a PPI analysis where I would like to contrast the connectivity of one parametrically modulated condition to another. So I have ConditionA pmodA and ConditionB pmodB, and I'm interested in seeing where those two pmods differentially affect connectivity. I'm unsure how to set up the gPPI analysis to do this. The relevant lines of my code that I have so far are:
P.Tasks={'1','ConditionA','ConditionB'};
P.Contrasts(1).left={'ConditionA'};
P.Contrasts(1).right={'ConditionB'};
P.Contrasts(1).Contrail=?? {'xpmodA^1' 'xpmodB^1}? how do I specify both pmods?
In general, is this the right setup to get what I'm looking for (PPI of task w/parametric modulators)?
Thank you for your help!
