Matching reads to many genomes with the $r$-index

Data Structures and Algorithms 2019-08-06 v1 Genomics

Abstract

The rr-index is a tool for compressed indexing of genomic databases for exact pattern matching, which can be used to completely align reads that perfectly match some part of a genome in the database or to find seeds for reads that do not. This paper shows how to download and install the programs ri-buildfasta and ri-align; how to call ri-buildfasta on a FASTA file to build an rr-index for that file; and how to query that index with ri-align. Availability: The source code for these programs is released under GPLv3 and available at https://github.com/alshai/r-index .
