Schematic overview of the sequence assembly. Schematic overview of the genome assembly steps. Illumina reads were assembled into contigs with Velvet. Unused reads were extracted and used for a second Velvet assembly with a different kmer length. 454 reads were assembled with CELERA. The 454-assembly was then subjected to homopolymer error correction with Illumina reads. The Illumina and 454 assemblies were merged into a non-redundant assembly using the Zorro pipeline. The assembly was then subjected to scaffolding using SSPACE and physical distance information. The final step involved gap closure with the IMAGE pipeline.
