Description of the four stages of the persistent homology and homological scaffolds analysis workflow. The data consist of a fully connected weighted network. The filtration is produced using the weight clique rank filtration. The persistent homology of the filtration is computed, and each cycle (or “hole”) is endowed with a birth and death time. The homological scaffolds are generated using the information from persistent homology.
