This archive contains genotypes in Plink PED format. Alleles are coded the same as in the archived data for Barson et al. (2015) (https://datadryad.org//resource/doi:10.5061/dryad.23h4q) Local_Adapt_QC.ped, Local_Adapt_QC.map: genotypes for the 188 juvenile fish and 198,829 SNPs retained after quality control steps. Bors.ped, Bors.map: genotypes for adult Borselva fish at 198,829 SNPs, from Barson et al. (2015) Teno_mainstem_adults.ped, Teno_mainstem_adults.map: genotypes for adult Teno mainstem fish at 198,829 SNPs, from Barson et al. (2015). Fish population inferred from the Structure results of Aykanat et al (2015) - Pop1, Pop2, or Intermediate - is shown in the first ('family id') column of the .ped file. Allele_conversion.txt: converts A, C, G, T alleles back to 1,2 coding, which relates to raw Axiom genotype codes as follows: Axiom genotype 0 = 1/1; Axiom genotype 1 = 1/2; Axiom genotype 2 = 2/2; Axiom genotype -9 = 0/0.
