WebAug 6, 2016 · We present a generalization of the Positional Burrows-Wheeler Transform, or PBWT, to genome graphs, which we call the gPBWT. A genome graph is a collapsed representation of a set of genomes described as a graph. In a genome graph, a haplotype corresponds to a restricted form of walk. WebThe transformation was originally discovered by David Wheeler in 1983, and was published by Michael Burrows and David Wheeler in 1994 [1]. The BWT has two main applications: compression and indexing. We will discuss both. First we discuss the transformation from T to BWT(T). 1.1 BWT via the BWM
