Nonetheless, contiguity is difficult to obtain if only low coverage data and/or only distantly related reference genome assemblies are available. Findings In order to improve genome contiguity, we have developed Cross-Species Scaffolding—a new pipeline that imports long-range distance information directly into the de novo assembly process by constructing mate-pair libraries in silico. Conclusions We show how genome assembly metrics and gene prediction dramatically improve with our pipeline by assembling two primate genomes solely based on ∼30x coverage of shotgun sequencing data.}, language = {en} } @misc{GrauHacklKoepflietal.2018, author = {Grau, Jos{\´e} Horacio and Hackl, Thomas and Koepfli, Klaus-Peter and Hofreiter, Michael}, title = {Improving draft genome contiguity with reference-derived in silico mate-pair libraries}, series = {GigaScience}, journal = {GigaScience}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-419225}, pages = {6}, year = {2018}, abstract = {Background Contiguous genome assemblies are a highly valued biological resource because of the higher number of completely annotated genes and genomic elements that are usable compared to fragmented draft genomes.

In this chapter, we discuss the possibilities to retrieve the necessary DNA sequence information from paleogenomic data obtained from fossil specimens, which can then be used to express and subsequently analyze the protein of interest. We discuss the problems specific to ancient DNA, including mis-coding lesions, short read length and incomplete paleogenome assemblies. Finally, we discuss an alternative, but currently rarely used approach, direct PCR amplification, which is especially useful for comparatively short proteins.}, language = {en} }
