WFDB软件介绍

  

What is the WFDB Software Package?

Effective use of PhysioBank data requires specialized software.

PhysioBank 数据的有效使用需要专门的软件。

 

 We have developed a large collection of such software over the past twenty years, and much of it is contained within the WFDB (WaveForm DataBase) Software Package, the GPLed successor to the MIT DB Software Package.

在过去的20年里，我们开发了一个很大的这样的软件，多数包含在WFDB（波形数据库）软件包中，它是MIT 数据库软件包的GPL协议下的 后继。（DB Software Package是WFDB 的前身）

 

The major components of the WFDB Software Package are the WFDB library, the WFDB applications for signal processing and automated analysis, and the WAVE software for viewing, annotation, and interactive analysis of waveform data.

WFDB 软件包的主要组成是WFDB库，用于信号处理和自动分析的WFDB应用程序，以及用于可视化、注释、波形数据交互式分析的软件WAVE.

 

A comprehensive collection of documentation, including tutorials and reference manuals, is also included in the package.

一个全面的文档集合，包括教程和参考手册，也包含在软件包中

 

The package is frequently updated; a summary of recent changes can be found here.

软件包经常被更新，近期所做更改的汇总可在这里找到

 

The package is written in highly portable C and can be used on all popular platforms, including GNU/Linux, MacOS/X, MS-Windows, and all versions of Unix.

该软件包是用高度可移植的C语言编写的，可以在所有流行的平台上使用，包括GNU/Linux，MacOS/ X，MS-Windows，及Unix的所有版本。

WFDB library

This is a set of functions (subroutines) for reading and writing files in the formats used by PhysioBank databases (among others). The WFDB library is LGPLed, and can be used by programs written in ANSI/ISO C, K&R C, C++, or Fortran, running under any operating system for which an ANSI/ISO or K&R C compiler is available, including all versions of Unix, MS-DOS, MS-Windows, the Macintosh OS, and VMS.

这是一个函数子集（子程序）用来读写 PhysioBank数据库使用格式（以及其它数据库） 文件。WFDB库满足LGPL协议，能够被ANSI/ISO C,K&R C, C++或Fortran语言所写的程序使用，能运行在任何可以使用ANSI/ISO或K&R编译器的操作系统上，包括所有版本的Unix，MS-DOS, MS-Windows, the Macintosh OS,  VMS.

 

Optionally, the WFDB library may be compiled with support for reading input directly from web (HTTP) and FTP servers without the use of a web browser or an FTP client. This optional feature allows applications linked with the WFDB library to view or analyze data such as those available from PhysioBank without the need to download entire records and to store them locally. To enable this feature, you will also need either the World Wide Web Consortium's libwww package, or the modern and enhanced alternative, libcurl.

可供选择地，WFDB库可以被编译成  支持从网络（HTTP）和FTP服务器直接读入，不需要使用网页浏览器或FTP客户端。这个可选特征允许连接了WFDB的应用程序 能够观察或分析 像PhysioBank中那样的 数据 ，不需要下载整个记录并保存它们到本地。要想使用这个特征，你也将需要 万维网联盟的libwww包，或现代强化版的libcurl。

 

Two optional packages provide interfaces between the WFDB library and software written in a variety of other languages, so that such software can have access to the full range of capabilities supported by current and future versions of the WFDB library.

The WFDB Toolbox for Matlab provides this interface for Matlab 7 (R14, 2004) or later, and the wfdb-swig package provides interfaces for software written using Perl, Python, C# (and other .NET languages), and Java. The wfdb-swig package can be readily extended for use with other target languages supported by SWIG, such as PHP, Ruby, TCL, and several versions of Lisp.

两个可选软件包提供WFDB库和 多种其它语言写的软件 的接口，因此这样的软件能使用 当前和未来版本的WFDB库支持的全部功能。

用于Matlab的WFDB工具箱为Matlab 7 （R14，2004）或更高版本 提供这样的接口，wfdb-swig 包 为Perl, Python, C# (其它 .NET 语言),  Java  写的软件 提供接口。wfdb-swig 包能容易地进行扩展，使之用于其它支持SWIG的目标语言，例如PHP, Ruby, TCL, 诸多版本的 Lisp。

 

The WFDB library is documented by the WFDB Programmer's Guide (available as HTML, PostScript, or PDF). Texinfo sources for the WFDB Programmer's Guide are included in the doc directory of the WFDB Software Package.

 WFDB 库配备的文档是WFDB Programmer's Guide（有HTML,PS,PDF格式）。WFDB Programmer's Guide 的 Tex 源码包含在WFDB软件包的doc目录中。

WFDB applications

A large set of well-tested, interoperable command-line tools for signal processing and automated analysis is included in the app, convert, and psd directories of the WFDB Software Package.

一大批经良好测试，交互性的 用于信号处理和自动分析的 命令行工具 包含在WFDB软件包的app，convert，psd目录中。

 

These applications are described in the WFDB Applications Guide (available as HTML, PostScript, or PDF). The troff (Unix man page) sources for the WFDB Applications Guide are included in the doc directory of the WFDB Software Package.

这些应用程序在文档WFDB Applications Guide中有描述（有HTML,PS,PDF格式）。WFDB Applications Guide 的 troff（Unix 主页）源码包含在WFDB软件包的doc目录中。 

 

Two American National Standards, ANSI/AAMI EC38:1998 (Ambulatory Electrocardiographs) and ANSI/AAMI EC57:1998 (Testing and Reporting Performance Results of Cardiac Rhythm and ST Segment Measurement Algorithms) require the use of several of the WFDB applications for evaluation of certain devices and algorithms. For details, see Evaluating ECG Analyzers in the WFDB Applications Guide.

两个美国国家标准， ANSI/AAMI EC38:1998 (动态心电图机) 和 ANSI/AAMI EC57:1998 (测试和报告心脏节律和ST段测量算法的性能结果)要求使用几个WFDB应用程序来评估某些设备和算法。详情请见WFDB Application Guide 中的Evaluating ECG Analyzers（ECG分析器评估）。

WAVE for GNU/Linux, FreeBSD, Mac OS/X, MS-Windows, Solaris, and SunOS

WAVE is an extensible interactive graphical environment for manipulating sets of digitized signals with optional annotations. WAVE is built using the WFDB library developed for physiologic signal processing, so it can be applied to any of a wide variety of data formats supported by the WFDB library. WAVE can run on GNU/Linux or FreeBSD PCs, Mac OS X, MS-Windows PCs, and Sun workstations, or on any other systems to which the open-source XView toolkit has been ported; in addition, it can be accessed remotely using networked PCs, Macintoshes, or other systems for which X11 servers are available.

WAVE  是一个可扩展的交互式图形环境，用来操作带有可选注释的数字信号。WAVE是建立在WFDB库基础上，所以它可以被应用到WFDB库支持的多种数据格式。WAVE 能运行在  GNU/Linux 或 FreeBSD PCs, Mac OS X, MS-Windows PCs,  Sun workstations, 或任意其它移植了开源XView 工具箱的系统。 除此之外，它能被联网的PC，Macintoshes,  或其它可以用X11服务器的系统 远程访问。

 

Among WAVE's capabilities are:
