Dear SPMers, I am confused about the adjustment in eigenvariate extraction from a VOI. Suppose an experiment that consists of three conditions C1, C2, and C3. My question is: Can I get an eigenvariate of time series data that removes contribution from C3 if I compute with adjustment with an F contrast [1 0 0 ;0 1 0; 0 0 0] ? Thank you!
