Assembly metrics for H. volcanii DS2.

Reference-based assembly metrics on ten assemblies of H. volcanii DS2 (Volc) dataset. “scaf” indicates an assembly that has been scaffolded, while “ctg” indicates no scaffolding. Labels “-CDS”, “-N50”, and “-LCB” indicate SOAPdenovo assemblies run with parameter combinations that minimized broken coding sequences, maximized scaffold N50, and minimized LCB (Locally Collinear Block) count, respectively. For A5, assembly “scaf-QC” has been broken using the A5QC algorithm and rescaffolded using SSPACE. The DCJ Distance is the Double-Cut-and-Join distance [35], a measure of the minimum number of rearrangement operations required to transform one genome assembly into another.
