MaSuRCA assembler

MaSuRCA is whole genome assembly software. It combines the efficiency of the de Bruijn graph and Overlap-Layout-Consensus (OLC) approaches. MaSuRCA can assemble data sets containing only short reads from Illumina sequencing or a mixture of short reads and long reads (Sanger, 454, Pacbio and Nanopore).
If you use MaSuRCA in your work, please cite our paper:

Zimin, A. et al. The MaSuRCA genome Assembler. Bioinformatics (2013). doi:10.1093/bioinformatics/btt476

UPDATE (July 2016): the MaSuRCA system now includes a new module to build mega-reads for hybrid Pacbio (or Nanopore) + Illumina de novo assembly, which is described in a forthcoming paper.
One can supply either Pacbio or Nanopore reads (not both) as PACBIO=file.fa or NANOPORE=file.fa in the configuration file. All Pacbio or Nanopore reads must be in a single fasta file! To obtain the latest SOURCE CODE of MaSuRCA and compilation instructions, see this page. BINARIES for various Linux distributions are NOT YET AVAILABLE and they are coming soon. Please check out the MaSuRCA blog at From now on all development and release announcements will be posted there.
