Nexus是一种文件格式，旨在包含用于计算机程序的系统数据。格式的目标是允许将来的扩展，包括各种信息，独立于特定的计算机操作系统，并通过程序轻松处理。为此，格式是模块化的，其中一个由单独的块组成的文件，每个块包含一种特定的信息，以及由标准化命令组成。公共区块（包含多个程序使用的信息）内部有关分类单元，形态和分子特征，距离，遗传代码，假设，集合，树木等的信息；私人块包含与单个程序相关的信息。给出了公共区块中命令的详细说明。提供了用于阅读和编写Nexus文件和扩展格式的准则。
NEXUS is a file format designed to contain systematic data for use by computer programs. The goals of the format are to allow future expansion, to include diverse kinds of information, to be independent of particular computer operating systems, and to be easily processed by a program. To this end, the format is modular, with a file consisting of separate blocks, each containing one particular kind of information, and consisting of standardized commands. Public blocks (those containing information utilized by several programs) house information about taxa, morphological and molecular characters, distances, genetic codes, assumptions, sets, trees, etc.; private blocks contain information of relevance to single programs. A detailed description of commands in public blocks is given. Guidelines are provided for reading and writing NEXUS files and for extending the format.
