Structure formatted file containing 1137 SNPs across 232 fish in main analyses

This file is formatted for input into the program STRUCTURE. It contains 1137 SNPs across 232 summer flounder. These were the individuals used in the main analyses, and this file was used to create the input files for BayEnv2. The first column identifies an individual fish. There are two rows for every fish. The second column is a population identifier. Columns 3-1139 are SNPs. Values of 1-4 indicate nucleotides (A = 1, T = 2, G = 3, C = 4). Missing data are indicated by -9
