SPM Summary

Specify the specific linear model for your experiment (each design matrix column corresponds with a bi term being estimated in the model equation), including a gCBF correction term.
- Yi = g1ib1 + g2ib2 + ... + gKibK + (Dgi)bg + xi
Specify how each scan contributes to each factor in the linear model with the elements of the design matrix.
Specify your null hypothesis with a contrast.
- e.g., Ho: c1b1 - c2b2 = 0
