Memory Efficient De Bruijn Graph Construction

Massively parallel DNA sequencing technologies are revolutionizing genomics research. Billions of short reads generated at low costs can be assembled for reconstructing the whole genomes. Unfortunately, the large memory footprint of the existing de novo assembly algorithms makes it challenging to get the assembly done for higher eukaryotes like mammals. In this work, we investigate the memory i...

GPU-Accelerated Bidirected De Bruijn Graph Construction for Genome Assembly

De Bruijn graph construction is a basic component in de novo genome assembly for short reads generated from the second-generation sequencing machines. As this component processes a large amount of data and performs intensive computation, we propose to use the GPU (Graphics Processing Unit) for acceleration. Specifically, we propose a staged algorithm to utilize the GPU for computation over larg...

De Bruijn Graph Homomorphisms and Recursive De Bruijn Sequences

This paper presents a method to find new de Bruijn cycles based on ones of lesser order. This is done by mapping a de Bruijn cycle to several vertex disjoint cycles in a de Bruijn digraph of higher order and connecting these cycles into one full cycle. We characterize homomorphisms between de Bruijn digraphs of different orders that allow this construction. These maps generalize the well-known ...

Construction for de Bruijn Sequences with Large Orders

Sequences generated by maximum-period nonlinear feedback shift registers are known as de Bruijn sequences. The problem of designing de Bruijn sequences has received considerable attention. There is only one full cycle in the state graph of de Bruijn sequences. Most popular algorithms for generating de Bruijn sequences start from a nonsingular linear feedback shift register producing several sho...

A Self-stabilizing General De Bruijn Graph

Searching for other participants is one of the most important operations in a distributed system. We are interested in topologies in which it is possible to route a packet in a fixed number of hops until it arrives at its destination. Given a constant d, this paper introduces a new self-stabilizing protocol for the q-ary d-dimensional de Bruijn graph (q = d √ n) that is able to route any search...
