Example color-coded heatmap and bar plots generated by PySmooth. (a) Color-coded heatmaps of the original genotype file from Fig. 1a. After singletons identification by PySmooth, the heatmap is shown in (b), and after genotype correction, the heatmap is shown in (c). The heatmap in (c) doesn’t contain singletons and missing labels. Each column in the heatmap represents a sample, the rows represent the markers. Corresponding bar plots of original genotype file, after singletons identification, and correction are shown in (d), (e), and (f), respectively. The y-axis represents the percentage of each genotype label in the samples. A, B, H, S, and U represent reference parent homozygous, alternate parent homozygous, heterozygous, singletons, and missing data, respectively
