Webb16 dec. 2008 · Background We have developed a new computational algorithm, Shape-IT, to infer haplotypes under the genetic model of coalescence with recombination developed by Stephens et al in Phase v2.1. It runs much faster than Phase v2.1 while exhibiting the same accuracy. The major algorithmic improvements rely on the use of binary trees to … Webb28 feb. 2013 · Samples (505,859 SNPs) were phased with SHAPEIT using as a reference the HapMap3 genetic maps . A coancestry matrix was constructed using ChromoPainter [16] with the default settings. FineSTRUCTURE [16] was used to perform an MCMC iteration on the coancestry matrix generated by ChromoPainter using 10,000,000 burnin and … incandie mouawad cultura
Phasing with SHAPEIT
WebbSHAPEIT3 commands are very similar to SHAPEIT2, with a few additional arguments to enable its fast scaling. Simply enabling the --fast flag should be sufficient for most … WebbSHAPEIT is a fast and accurate method for estimation of haplotypes (aka phasing) from genotype or sequencing data. SHAPEIT has several notable features: Linear complexity with the number of SNPs and conditioning haplotypes. Whole chromosome GWAS scale datasets can be phased in a single run. Phasing individuals with any level of relatedness WebbSHAPEIT3 commands are very similar to SHAPEIT2, with a few additional arguments to enable its fast scaling. Simply enabling the --fast flag should be sufficient for most users: shapeit3 -B example/gwas -M genetic_map.txt -O out --threads 2 --cluster-size 500 A full list of arguments are listed below. incandescent watts to led watts calculator
