Abstract

Throughout the book we mostly assume the genome sequence under study to be known. In this chapter we look at strategies for how to assemble fragments of DNA into longer contiguous blocks, and eventually into chromosomes. This chapter is partitioned into sections roughly following the workflow of a de novo assembly project, namely, error correction, contig assembly, scaffolding, and gap filling. Algorithms working with de Bruijn graphs and overlap graphs are studied.
