Graphical pangenomics
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. WebPractical Graphical Pangenomics Pangenomic methods Standard approaches to genome inference and analysis relate sequences to a single linear reference genome. This is …

In the pangenome, we can identify three sets of genes: Core, Shell, and Cloud genome. The Core genome comprises the genes that are present in all genomes analyzed. To avoid dismissing families due to sequencing artifacts some authors consider the softcore (>95% occurrence). See more In the fields of molecular biology and genetics, a pan-genome (pangenome or supragenome) is the entire set of genes from all strains within a clade. More generally, it is the union of all the genomes of a See more Core Is the part of the pangenome that is shared by every genome in the tested set. Some authors have divided the core pangenome in hard core, those families of homologous genes that has at least one copy of the family … See more The pan-genome can be somewhat arbitrarily classified as open or closed based on the alpha value of the Heap law: $${\displaystyle N=kn^{-\alpha }}$$ • $${\displaystyle N}$$ Number of gene families. • $${\displaystyle n}$$ Number of genomes.
