Fig. 4

Error rate (%) of synteny identification in fragmented assemblies. The error rate is defined as the difference between the synteny coverage calculated with the original genome (almost 100%) and that in fragmented assemblies, where the original assembly was used as the reference in both cases. 5% and 2% error rate positions are marked by grey solid and dashed lines, respectively. Different pairs in synteny identification are separated in different panels. The upper panels are self-comparisons, while the bottom are comparisons between closely related species. Note that for a clear visualization of pattern changes, the scales of error rate are different between upper and bottom panels. Colors represent different types of synteny detection programs. The letters a, b, c and d denote the comparisons of C. elegans vs. C. elegans, S. ratti vs. S. ratti, C. elegans vs. C. briggsae, and S. ratti vs. S. stercoralis respectively
