Scrm, efficiently simulating long sequences using the approximated coalescent with recombination
Motivation: Coalescent based simulation software for genomic sequences allows the efficient in silico generation of short and medium-sized genetic sequences. However, the simulation of genome-size data sets as produced by Next-Generation sequencing (NGS) is currently only possible using fairly crude approximations.
Results: We present the Sequential Coalescent with Recombination Model (SCRM), a new method that efficiently and accurately approximates the coalescent with recombination, closing the gap between current approximations and the exact model. We present an efficient implementation and show that it can simulate genomic-scale data sets with an essentially correct linkage structure.
