## Introduction
-Minichain is designed to align long reads to pangenome graphs represented as DAGs. It can scale to pangenomes built from several human genome assemblies. We have incorporated a provably-good gap-sensitive co-linear chaining algorithm for filtering anchors (see [paper](#pub) for details). This algorithm enables accurate and fast long read alignments. Minichain uses seeding and base-to-base alignment code from [minigraph][minigraph].

### Sequence mapping
-Minichain can be used for both sequence-to-sequence alignment as well as sequence-to-graph alignment. A graph should be provided in either [GFA][gfa1] or [rGFA][rgfa]format. Users can run quick tests on [sample data](data/) using the following commands. The alignment output is provided in [PAF](https://github.com/lh3/miniasm/blob/master/PAF.md) and [GAF](https://github.com/lh3/gfatools/blob/master/doc/rGFA.md#the-graph-alignment-format-gaf) format respectively.

## Benchmark
-We have compared Minichain (v1.0) with existing sequence to graph aligners to demonstrate scalability and accuracy gains. Our experiments used human pangenome graphs built by using subsets of [94 high quality haplotype assemblies](https://github.com/human-pangenomics/HPP_Year1_Assemblies) provided by the Human Pangenome Reference Consortium, and [CHM13 human genome assembly](https://www.ncbi.nlm.nih.gov/assembly/GCA_009914755.4) provided by the Telomere-to-Telomere consortium. Using a simulated long read dataset with 0.5x coverage, and graphs of three different sizes, Minichain shows superior read mapping precision. For the largest DAG from 95 haplotypes, Minichain used 24 minutes and 25 GB RAM with 32 threads.
