In this paper we present a method for de novo genome assembly that splits the process into three stages: quasicontig assembly; contig assembly from quasicontigs; contig postprocessing with microassembly. The first stage uses de Bruijn graph, the second one uses overlap graph. We have carried out experiments of assembling the E. Coli genome (size ≈4.5 Mbp) andMaylandia zebra genome (size ≈1 Gbp). Advantage of proposed method is a low memory consumption.
