Selective sweeps should display localized, elevated and linked FST values between populations (Sabeti et al., 2006 ). SNP-wise Weir and Cockerham’s FST values were calculated by vcftools (v0.1.13; Danecek et al., 2011 ). In addition, the FST outlier test implemented in bayescan was conducted (Foll & Gaggiotti, 2008 ) using default settings. Finally, a haplotype based test, hapflk (Fariello, Boitard, Naya, SanCristobal, & Servin, 2013 ), was also used. First, we calculated the Reynolds distance matrix using the thinned data set. No outgroups were defined, 20 local haplotype clusters (K = 20) were specified and the hapflk statistic computed using 20 EM iterations (nfit = 20). Statistical significance was determined though the script “scaling_chi2_hapflk.py”. To adjust for multiple testing, we set the false discovery rate (FDR) level to 5% using qvalue / r (Storey, Bass, Dabney, & Robinson, 2019 ). Samples from the western and southern locations were grouped into their respective groups (South, N = 34 and West, N = 24) in all three tests.
step three.1 Genotyping
The entire genome resequencing research produced all in all, step 3,048 billion reads. Whenever 0.8% of them reads were continued which means thrown away. Of your own leftover checks out from the blended study place (3,024,360,818 checks out), % mapped towards genome, and % was in fact precisely paired. This new suggest breadth of publicity each individual try ?9.16. Continue reading
