tree topology of the simulated data

tree topology used to simulate sequence Folder tree structuredata/trees/tips_num/ asymmetric_0.5.unroot.tree asymmetric_1.0.unroot.tree asymmetric_2.0.unroot.tree where asymmetric_0.5.unroot.tree is used in the paper Credit by Gblocks and trimAl本数据集采用用于模拟序列的树拓扑结构，其文件夹树结构的数据存储路径为data/trees/tips_num/，包含asymmetric_0.5.unroot.tree、asymmetric_1.0.unroot.tree与asymmetric_2.0.unroot.tree三类文件；其中asymmetric_0.5.unroot.tree被该论文采用，相关分析方法归功于Gblocks与trimAl。
