Dear SPM experts,
In a DCM - RS analysis to a single subject I've specified and estimated a full model with 4 nodes (PCC, mPFC, LIPC and RIPC), but it´s not clear to me:
1. How could I get the 64 possible models (2^n(n-1)/2) from the full model? Should I specify them one by one?
2. How to reduce the number of models (Bayesian model reduction) at SPM in order to compare them?
I really appreciate any help you can provide.
