The folder includes 4 files in Structure format

1. noMAF_TBMU.structure.tsv
This files includes all SNPs genotyped in thick-billed murres only with no minor allele frequency (MAF) filter
2. MAF_TBMU.structure.tsv
This files includes all SNPs genotyped in thick-billed murres only with MAF < 0.05
3. MAF_TBMU_outliers_lositan.structure.tsv
This files includes only outlier SNPs (as identified by Lositan) genotyped in thick-billed murres only with MAF < 0.05
4. COMUandTBMU_firstSNP.structure.tsv
This file was used to test for presence of hybrids in the dataset and includes SNPs (only the first SNP for each locus) genotyped in common and thick-billed murres. No MAF filter applied.
