计算机程序TNT的1.5版本将标志点数据完全整合到系统发育分析中。标志点数据由末端分类单元的坐标（二维或三维）组成；TNT为内部节点重建形状，使得所有树枝的祖先形状和后代形状之间的差异总和达到最小；这个总和被用作树的分值。标志点数据可以单独分析，也可以与标准性状结合分析；在读取标志点数据集之后，TNT中所有适用的命令和选项都可以透明地使用。该程序继续实现以前版本中的所有类型的分析，包括离散性状和连续性状（现在可以以任何尺度读取，并由TNT自动重新调整尺度）。使用本文中描述的算法，对标志点数据的搜索可以比以前快数十到数百倍（快T到3T倍，其中T是分类单元的数量），从而使得即使在标准个人计算机上对标志点进行系统发育分析也是可行的。
Version 1.5 of the computer program TNT completely integrates landmark data into phylogenetic analysis. Landmark data consist of coordinates (in two or three dimensions) for the terminal taxa; TNT reconstructs shapes for the internal nodes such that the difference between ancestor and descendant shapes for all tree branches sums up to a minimum; this sum is used as tree score. Landmark data can be analysed alone or in combination with standard characters; all the applicable commands and options in TNT can be used transparently after reading a landmark data set. The program continues implementing all the types of analyses in former versions, including discrete and continuous characters (which can now be read at any scale, and automatically rescaled by TNT). Using algorithms described in this paper, searches for landmark data can be made tens to hundreds of times faster than it was possible before (from T to 3T times faster, where T is the number of taxa), thus making phylogenetic analysis of landmarks feasible even on standard personal computers.
