Phylogenetic Tree Reconstruction (PTreeRec) is a web-based tool for automatic phylogeny inferences from whole-genome sequences, which accepts files of DNA sequences in the FASTA format and allows users to save the output tree file, and displays the inferred tree through an applet in a web browser. PTreeRec involves three basic steps. First, regions of maximal segment pairs (MSPs) based on an all-against-all pairwise comparison of genomes are located. Second, a distance matrix is calculated from MSP scores or coverage. Finally, a phylogenetic tree is reconstructed by the neighbor-joining method.
系统发育树重建（PTreeRec）是一种基于网络的工具，用于从全基因组序列中自动推断系统发育，它接受FASTA格式的DNA序列文件，允许用户保存输出的树文件，并通过网页浏览器中的小程序显示推断出的树。PTreeRec包括三个基本步骤。首先，基于基因组的全基因组两两比较定位最大片段对（MSP）区域。其次，根据MSP得分或覆盖率计算距离矩阵。最后，通过邻接法重建系统发育树。
