Sep 14, 2021 · Gramtools enables multiscale variation analysis with genome graphs. Genome graphs allow very general representations of genetic variation; depending on the model and implementation, variation at different length-scales (single nucleotide polymorphisms (SNPs), structural varian...

Pan-genome graph construction is the process of creating a graph-based representation of the collective genome (the pan-genome) of a species or a group of organisms.

May 10, 2023 · Here we present the Minigraph-Cactus pangenome pipeline, which creates pangenomes directly from whole-genome alignments, and demonstrate its ability to scale to 90 human haplotypes from the...

Genome Graphs is a tool for displaying genome-wide data sets such as the results of genome-wide SNP association studies, linkage studies and homozygosity mapping. This section provides line-by-line descriptions of the controls on this page.

pggb builds pangenome variation graphs from a set of input sequences. A pangenome variation graph is a kind of generic multiple sequence alignment. It lets us understand any kind of sequence variation between a collection of genomes. It shows us similarity where genomes walk through the same parts of the graph, and differences where they do not.

Aug 2, 2019 · Algorithms for building a variant-aware human graph genome enable fast and accurate genotyping without huge memory requirements. The linear sequence of three billion nucleotides that makes up...

Here, we survey various projects underway to build and apply these graph-based structures—which we collectively refer to as genome graphs—and discuss the improvements in read mapping, variant calling, and haplotype determination that genome graphs are expected to …

Sep 24, 2020 · Aligning sequences to genome graphs is key to many applications, including error correction, genome assembly, and genotyping of variants in a pangenome graph. Yet, so far, this step is often prohibitively slow. We present GraphAligner, a …

A graph-based representation of multiple genomes, or a graph pangenome, is replacing the linear reference genome. This means completely rethinking well-established procedures to analyze, store, and access information from genome representations.

Jan 14, 2019 · Here we present a graph genome pipeline for building, augmenting, storing, querying and variant calling from graph genomes composed of a population of genome sequences. We show that graph...
