<a name="intro"> <h2>What is the WFDB Software Package?</h2></a>
<p>
Effective use of PhysioBank data requires specialized software. 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 <a href="https://physionet.org/physiotools/wfdb/COPYING">GPL</a>ed successor to the MIT <a href="https://physionet.org/physiotools/old/">DB Software Package</a>.</p>
<p>
The major components of the WFDB Software Package are the <a href="https://physionet.org/physiotools/wfdb.shtml#library">WFDB library</a>, about 75 <a href="https://physionet.org/physiotools/wfdb.shtml#applications">WFDB
applications</a> for signal processing and automated analysis, and the <a href="https://physionet.org/physiotools/wfdb.shtml#WAVE"><em>WAVE</em></a> software for viewing, annotation, and
interactive analysis of waveform data. A comprehensive collection of <a href="https://physionet.org/physiotools/manuals.shtml">documentation</a>, including tutorials and reference
manuals, is also included in the package.</p>
<p>
The package is frequently updated; a summary of recent changes can be found <a href="https://physionet.org/physiotools/wfdb/NEWS">here</a>. 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.</p>
<a name="library"> <h3>WFDB library</h3></a>
<p>
This is a <a href="https://physionet.org/physiotools/wfdb/lib/">set of functions</a> (subroutines) for
reading and writing files in the formats used by PhysioBank databases
(among others). The WFDB library is <a href="https://physionet.org/physiotools/wfdb/lib/COPYING.LIB">LGPL</a>ed, 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.</p>
<p>
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 <a href="https://physionet.org/physiobank/">PhysioBank</a> 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 <a href="https://physionet.org/physiotools/libwww/"><code>libwww</code></a> package,
or the modern and enhanced alternative, <a href="https://physionet.org/physiotools/libcurl/"><code>libcurl</code></a>.</p>
<p>
The WFDB library is documented by the <em>WFDB Programmer's Guide</em>
(available as <a href="https://physionet.org/physiotools/wpg/wpg.htm">HTML</a> or <a href="https://physionet.org/physiotools/wpg/wpg.pdf">PDF</a>).
Texinfo sources for the <em>WFDB Programmer's Guide</em> are included
in the <a href="https://physionet.org/physiotools/wfdb/doc/"><code>doc</code></a> directory of the WFDB Software
Package.</p>
<a name="applications"> <h3>WFDB applications</h3></a>
<p>
A large set of well-tested, interoperable command-line tools for signal
processing and automated analysis is included in the <a href="https://physionet.org/physiotools/wfdb/app/"><code>app</code></a>, <a href="https://physionet.org/physiotools/wfdb/convert/"><code>convert</code></a>, and <a href="https://physionet.org/physiotools/wfdb/psd/"><code>psd</code></a> directories of the WFDB Software Package.
These applications are described in the <em>WFDB Applications Guide</em>
(available as <a href="https://physionet.org/physiotools/wag/wag.htm">HTML</a> or <a href="https://physionet.org/physiotools/wag/wag.pdf">PDF</a>). The
<code>troff</code> (Unix <code>man</code> page) sources for the <em>WFDB Applications
Guide</em> are included in the <a href="https://physionet.org/physiotools/wfdb/doc/"><code>doc</code></a> directory
of the WFDB Software Package.</p>
<p>
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
<a href="https://physionet.org/physiotools/wag/eval.htm">Evaluating ECG Analyzers</a> in the
<em>WFDB Applications Guide</em>.</p>
<a name="WAVE"> <h3><em>WAVE</em> for GNU/Linux, FreeBSD, Mac OS/X,
MS-Windows, Solaris, and SunOS</h3></a>
<p> <em>WAVE</em> is an extensible interactive graphical environment
for manipulating sets of digitized signals with optional annotations.
<em>WAVE</em> 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. <em>WAVE</em>
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.</p>
<p>
Among <em>WAVE</em>'s capabilities are:</p>
<ul>
<li> fast display of waveforms and annotations at various calibrated scales
</li><li> fast access to any portion of a recording, with caching and `read-ahead'
heuristics to improve efficiency and reduce network traffic
</li><li> forward and backward searches for annotation patterns
</li><li> graphical annotation editing using standard or user-defined annotations
</li><li> variable-speed superimposition display (simulation of triggered
oscilloscope display with persistence; can be run forward or backward)
</li><li> high-resolution printing of user-selected signal segments
</li><li> extremely flexible control of external signal-processing and analysis
programs (menus may be reconfigured by the user while <em>WAVE</em> is
running)
</li><li> `remote' mode: external programs such as Web browsers can control
<em>WAVE</em>'s display
</li><li> on-line `spot' help for all controls, with additional topic-oriented
on-line help
</li></ul>
<p>
A complete set of sources for <em>WAVE</em> is included in the <a href="https://physionet.org/physiotools/wfdb/wave/"><code>wave</code></a> directory of the WFDB Software Package.
The <em>WAVE User's Guide</em> (available as <a href="https://physionet.org/physiotools/wug/wug.htm">HTML</a> or <a href="https://physionet.org/physiotools/wug/wug.pdf">PDF</a>) contains
both tutorial and reference material. The LaTeX source for the <em>WAVE User's
Guide</em> is included in the <a href="https://physionet.org/physiotools/wfdb/doc/"><code>doc</code></a> directory of
the WFDB Software Package.</p>
<p> For convenience, XView sources are available <a href="https://physionet.org/physiotools/xview/">here</a>, as are XView binaries for
GNU/Linux, Mac OS X, and MS-Windows, instructions
for installing them, as well as information about how to find or
create XView libraries for FreeBSD, Solaris, and other
versions of Unix. The source and binary packages contain the
<code>xview</code> and <code>olgx</code> libraries needed by <em>WAVE</em>.</p>
<!--
<p>
Two other viewers for MS-Windows, <a name="GTKWave"><em>GTKWave</em>
and <a name="WVIEW"><em>WVIEW</em>, are no longer under active development;
neither is as capable as <em>WAVE</em>.
<a name="GTKWave"><h4><em>GTKWave</em> (Beta) for GNU/Linux and MS
Windows</h4></a>
<p>
<a href="beta/gtkwave/"><em>GTKWave</em></a> is a reimplementation of the
original <em>WAVE</em> using the Gimp Tool Kit (GTK+) in place of XView.
Unlike XView, GTK+ is maintained and has been ported to a large number of
operating systems, including all popular versions of Unix, MS Windows, and Mac
OS/X. In addition to sources, ready-to-run binaries for GNU/Linux and MS
Windows are available. The current release is still in development and should
be considered usable but potentially unstable.
<a name="WVIEW"><h4><em>WVIEW</em> for MS Windows 3.x (deprecated)</h4></a>
<p>
This program is a browser with display capabilities similar to those of
<em>WAVE</em> (it lacks <em>WAVE</em>'s facilities for annotation editing and
control of external analysis programs, however).
<p>
<a href="beta/gtkwave"><em>GTKWave</em></a> is much more capable than
<em>WVIEW</em>, and is highly recommended for use under 32-bit versions of MS
Windows (9x/NT/2000/ME/XP).
<em>WVIEW</em> is not currently maintained or supported. Sources for
<em>WVIEW</em> are included in the <a href="wfdb/wview/"><code>wview</code></a>
directory of the WFDB Software Package; these will be removed once
<em>GTKWave</em> 1.0 has been released.

<a name="optional"><h2>Related software packages</h2></a>
<p>
The packages described in this section allow use of the WFDB software from
other environments and programming languages. These packages are not
included in the WFDB Software Package; they must be installed separately.</p>
<a name="toolbox"><h3>WFDB Toolbox for MATLAB</h3></a>
<p>
The <a href="https://physionet.org/physiotools/matlab/wfdb-app-matlab/">WFDB Toolbox for MATLAB</a> provides
access from MATLAB to more than 20 of the applications included in the WFDB
Software Package. The toolbox provides MATLAB and Java wrappers for these
applications, and an installer that runs within MATLAB to install both the
toolbox itself and the precompiled WFDB Software Package executables upon which
it relies. The toolbox can be used with 64-bit MATLAB R2010b or later on
GNU/Linux, Mac OS X, and MS-Windows.</p>
<a name="wfdb-swig"><h3>WFDB-SWIG for Java, Perl, Python, and more</h3></a>
<p>
The <a href="https://physionet.org/physiotools/wfdb-swig.shtml">wfdb-swig</a> package provides
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 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 <a href="http://www.swig.org/" target="other">SWIG</a>, such as PHP, Ruby, TCL, and several versions
of Lisp.</p>
