Indexing Graphs for Path Queries with Applications in Genome Research
Abstract
We propose a generic approach to replace the canonical sequence representation of genomes with graph representations, and study several applications of such extensions. We extend the Burrows-Wheeler transform (BWT) of strings to acyclic directed labeled graphs, to support path queries as an extension to substring searching. We develop, apply, and tailor this technique to a) read alignment on an extended BWT index of a graph representing pan-genome, i.e., reference genome and known variants of it; and b) split-read alignment on an extended BWT index of a splicing graph. Other possible applications include probe/primer design, alignments to assembly graphs, and alignments to phylogenetic tree of partial-order graphs. We report several experiments on the feasibility and applicability of the approach. Especially on highly-polymorphic genome regions our pan-genome index is making a significant improvement in alignment accuracy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
