Graphical pangenomics
WebPPanGGOLiN builds pangenomes through a graphical model and a statistical method to partition gene families in persistent, shell and cloud genomes. It integrates both information on protein-coding genes and their genomic neighborhood to build a graph of gene families where each node is a gene family and each edge is a relation of genetic contiguity.

These models offer the opportunity to study the entire genomic diversity of a population, including structurally complex regions.
WebTo do so I formalize the concept of a variation graph to link genomes to a graphical model of their mutual alignment that is capable of representing any kind of genomic variation, both small and large. As this model combines both sequence and variation information in one structure it serves as a natural basis for resequencing.
