$r$-indexing Wheeler graphs

no code implementations29 Jan 2021 Travis Gagie

Let $G$ be a Wheeler graph and $r$ be the number of runs in a Burrows-Wheeler Transform of $G$, and suppose $G$ can be decomposed into $\upsilon$ edge-disjoint directed paths whose internal vertices each have in- and out-degree exactly 1.

Compressing and Indexing Aligned Readsets

no code implementations19 Sep 2018 Travis Gagie, Garance Gourdel, Giovanni Manzini

Specifically, we build a labelled tree by taking the assembled genome as a trunk and grafting onto it the reads that align to it, at the starting positions of their alignments.

Using Minimum Path Cover to Boost Dynamic Programming on DAGs: Co-Linear Chaining Extended

1 code implementation24 May 2017 Anna Kuosmanen, Topi Paavilainen, Travis Gagie, Rayan Chikhi, Alexandru I. Tomescu, Veli Mäkinen

Here we extend the approach so that one of the inputs can be a directed acyclic graph (DAGs), e. g. a splicing graph in transcriptomics or a variant graph in pan-genomics.

Range Quantile Queries: Another Virtue of Wavelet Trees

1 code implementation27 Mar 2009 Travis Gagie, Simon J. Puglisi, Andrew Turpin

A range quantile query takes a rank and the endpoints of a sublist and returns the number with that rank in that sublist.
