Error in detecting simulated introgression tracts of different lengths in simulated hybrids. RMSE was calculated between the true dosage and ELAI dosages of the simulated hybrids, for different homozygous introgressed segment lengths (0.05, 0.5, 1, 2, and 5 Mb). Each panel shows, for each tested length, the RMSE values (y-axis) for ELAI runs with the numbers of lower clusters (c = 5), different numbers of generations (mg = 5, 10, 20, and 30) on the x-axis, and four different SNP sets (10 K SNPs, 100 K SNPs, evenly distributed SNPs—1 SNP/5 kb, and all SNPs—1 M SNPs).
