Evaluation of IBD estimation at different coverages. y-axis shows per-window performance accuracy calculated over 60 simulations with each relatedness case and six different coverages shown on x-axis. The error bars are drawn at 1 standard deviation from the mean. Here, accuracy corresponding to relatedness cases for parent–child and identical individuals is always 1 and overlaps with each other. Accuracy is defined as the proportion of correctly predicted IBD states, when compared to the central position of the window
