Query: Selscan: an efficient multi-threaded program to perform EHH-based scans
  for positive selection   Haplotype-based scans to detect natural selection are useful to identify
recent or ongoing positive selection in genomes. As both real and simulated
genomic datasets grow larger, spanning thousands of samples and millions of
markers, there is a need for a fast and efficient implementation of these scans
for general use. Here we present selscan, an efficient multi-threaded
application that implements Extended Haplotype Homozygosity (EHH), Integrated
Haplotype Score (iHS), and Cross-population Extended Haplotype Homozygosity
(XPEHH). selscan accepts phased genotypes in multiple formats, including TPED,
and performs extremely well on both simulated and real data and over an order
of magnitude faster than existing available implementations. It calculates iHS
on chromosome 22 (22,147 loci) across 204 CEU haplotypes in 353s on one thread
(33s on 16 threads) and calculates XPEHH for the same data relative to 210 YRI
haplotypes in 578s on one thread (52s on 16 threads). Source code and binaries
(Windows, OSX and Linux) are available at https://github.com/szpiech/selscan .
