WebApr 11, 2024 · Widely used genotyping methods for sequencing data 16,17,18,19,20 are based on short-read alignments to a reference genome or pangenome graphs, which include possible alternative alleles 21,22,23 ... WebApr 5, 2024 · vcf: A standard text-based format that represents a pangenome graph as sites of variation along a reference. VCFs exported from the graph are nested, and by default vcfbub is used to flatten them. vg : vg 's native packed-graph format, can be read and written by vg but does not scale well with the number of paths.
