Allows to create true diploid de novo assemblies. Supernova can separate homologous chromosomes over long distances, in this sense capturing the true biology of a diploid genome. The Supernova approach is based on seven human samples. These assemblies used identical code, with same parameters as a ‘pushbutton’ process that ran in two days on a single server. The diploid human assemblies from this tool use sequence from the same sample. This approach yields much longer phase blocks than the previous diploid human assemblies. In this case, the diploid human assemblies are the first to be validated using finished sequence from the same sample and the first whose phasing accuracy has been validated using parental sequences
