This README file relates to RADseq data used in the paper: Shipham, A., Joseph, L., Schmidt, D.J., Drew, A., Mason, I., Hughes, J.M. (2018ms). Dissection by genomic and plumage variation of a geographically complex hybrid zone between two Australian non-sister parrot species, Platycercus adscitus and P. eximius Dataset Title: INTROGRESS_Data_77Individuals Dataset Description: RADseq data used for analyses in the Introgress R package. This file contains data from 77 rosellas and 152 loci shown to display interspecific alele frequency differentials greater than or equal to 0.8. The file is a modification of the 'haplotypes.tsv' file generated by STACKS. Rows: Row 1: Contains column headings Row 2: Data begins Columns: Column 1: Catalogue/Locus ID Column 2: Data type (C = Co-dominant) Column 3: Individual haplotype data begins Missing Data Value: NA Data values: Data is represented by SNP haplotypes. Using data in introgress: The data within this file was divided into 4 text files that were then entered into R using the 'read.table' function. Files were as follows: (1) Locus data: Includes columns 1 & 2 [Relevant introgress argument = 'loci.data']. (2) Eastern rosella group: Includes individuals with the following ID: B31672,B32358,B34044,B34057,B34138,B34280, B34906,B44997,B45068,B45069,B45110,B45111,B49163,B49176,B49215,B49216,B55664,B55665, B55672,B55731,B55740 [Relevant introgress argument = 'parental2'] (3) Hybrid rosella group: Includes individuals with the following ID: B41904,B44815,B44816,B47116,B49299,B49318, B51264,B55538,B55561,B55674,B55676,B55681,B55692,B55693,B55699,B55700 [Relevant introgress argument = 'admix.gen'] (4) Pale-headed rosella group: Includes individuals with the following ID: 20528,B29709,B29824,B29911,B29913,B31163, B31596,B32256,B34097,B41376,B41583,B41584,B41892,B43073,B43138,B43143,B43145,B43414, B43415,B43804,B43843,B44160,B49055,B49085,B51486,B51746,B55500,B55741,B55760,B55780, B55785,B55786,B55813,B55815,B55816,B55818,B55852,B55853,B55865,B55866 [Relevant introgress argument = 'parental1'] For further information contact: ashlee.shipham@griffithuni.edu.au [Ashlee Shipham]
