This step-by-step guide accompanies a pair of tutorial papers on group effective connectivity analysis, published in NeuroImage (see below). The guide walks through a DCM for fMRI analysis and testing hypotheses at the group level using PEB.
You may wish to start with the theory papers, which explain how each step in the analysis works:
1. A guide to group effective connectivity analysis, part 1: first level analysis with DCM for fMRI
2. A guide to group effective connectivity analysis, part 2: second level analysis with PEB
