有人看了WEGENE最新出的论文吗?

由于是英文版，我英语不大好。
为什么这图2的CD两张图会不一样。
The most populated 1st-level (a), 2nd-level (b), and 3rd-level (c) cluster in each prefecture. d. The 3rd-level cluster with the largest odds ratio in each prefecture. e. The spatial distribution of the 3rd-level subclusters in Jiangsu province is accompanying the linguistic-cultural division. The most populated clusters were shown. f. Three major clans in Guangdong, Canton, Hakka (falling into two clusters), and Min-Chaoshan, can be distinguished from the haplotype network clusters. The clusters with the largest odds ratio were shown. g-h. The paths of the Zou Xikou (g) and Chuang Guandong (h) migration waves. In panels a-d, 50% transparency was applied to the prefectures with small sample sizes (n < 10), and prefectures with no valid samples were left blank.
按论文描述图C应该是以“三级”分类prefecture我理解为地级市，占比最大的做的图。
可是图D确在细节处有很大的不同，比如胶东地区，福建。
在二级分类的情况下，赣州汉与东南的闽客浙南一组，但继续细分，三级下赣州和中南组归为一类图C，但图D又归入珠江流域的客家组。
还没完，继续细分，四级分类下，赣州与梅州龙岩汕尾聚成一组，脱离珠江流域的客家组。
还有论文给出了闽粤三个族群与二级下的北方组的关系，却没有给出闽粤与华中和华东和西南组的关系。我想知道邻近的中南组合和二级下的华北组IBDshareing能透露一下吗。
有微基因的大佬知道原因吗？
