A simple demo of pangenome graph about precise gene comparison in PPanG. (a) The pangenome sequence graph only.
Source sequences are presented on the right and variations are underlined. (b) The pangenome sequence graph with gene features visualized. Two exons are drawn in gray bars over genome tracks according to genome annotations. As the figure shows, the junctions of exon 1 from sequence 1, sequence 2 and sequence 4 are identical, although there is a substitution from “GA” to “CT”. In sequence 3, exon 2 is identical but exon 1 is absent due to the deletion, which represents a gSV. There is not any gray bar in sequence 5, indicating that all gene features are absent due to the large deletion, which represents an absent variation. Notably, the second gray bar of sequence 4 appears longer than the others, but actually exon 2 of sequence 4 is shorter because of the missing node of “ATG…TA”, which may be counterintuitive
