wave, gtkwave - waveform analyzer, viewer, and editor
wave
-r record[+record ...] [ options ... ]
gtkwave -r record[+record ...] [ options ... ]
wave can be used to
view the specified WFDB record or records on any display controlled by
an X11 server. gtkwave provides most of the same facilities with a newer
GUI under either Unix or MS-Windows. Both applications include facilities
for interactive annotation editing. The keyboard and mouse are used to control
the display interactively. First-time users should read the WAVE User's Guide.
(One way to do this is by pointing your Web browser to file:///usr/help/html/wug/wug.htm,
or to http://www.physionet.org/physiotools/wug/
for the latest version.)
If
you specify more than one record, a separate wave process is started for
each record. Note that all records to be opened must be listed in a single
command-line argument following -r, with + characters (not spaces) between
the record names. See `Running two or more WAVE processes' below.
Use the
left mouse button to make selections, and the right mouse button to open
menus (indicated by triangular glyphs at the right end of some buttons).
See the Guide or the on-line manual for notes on annotation editing.
Options
are:
- -a annotator
- Open the specified annotation file for the previously
specified record or records.
- -dpi xx[xyy]
- Calibrate wave for use with a display
having a resolution of xx (by yy) dots per inch.
- -f time
- Open the record(s)
beginning at the specified time.
- -g
- Use shades of grey only, even on a color
monitor.
- -H
- Read the signal files in high-resolution mode (default: standard
mode). These modes are identical for ordinary records. For multifrequency
records, the standard decimation of oversampled signals to the frame rate
is suppressed in high-resolution mode (rather, all other signals are resampled
at the highest sampling frequency).
- -m
- Use monochrome (usually black and
white) only, even on a color or greyscale monitor. The line styles selected
by the -m option may be easier to distinguish on some greyscale monitors
than the default shades of grey.
- -O
- Use overlay graphics for maximum speed
and display quality if possible. This is the usual default if the X server
supports a PseudoColor or GrayScale visual. This option exists only to
force use of overlay graphics if a different mode has been chosen as the
default.
- -s signal-list
- Initialize the signal list. By default, the signal
list includes all available signals, in numerical order.
- -S
- Use the standard
(shared) color palette, even if it is possible to modify the palette. Using
this option conserves color resources if you have other applications that
use non-standard colors, at the expense of some speed in redrawing the display.
The -S option may be used in combination with the -g option if desired.
- -Vx
- Set display option x. See `Display Options' below for details.
Note that wave
queries the X server to determine the display capabilities and resolution;
it is not necessary to use the -g, -m, or -S options unless you wish to restrict
wave's use of the available capabilities. Use the -dpi option to override
the server's default resolution if it is incorrect and cannot be changed
otherwise (see comments below under `Resources').
The system on which wave
runs (the ``host'' system) need not be the same as the system to which your
keyboard, mouse and display are connected (the ``local'' system), provided
only that the host and local systems are on the same network. If you wish
to run wave remotely, simply log in to the host using ssh, which normally
handles display redirection automatically. If you use some other method
to log in remotely, such as rlogin (not recommended) or telnet (not recommended),
it is usually necessary to grant permission for the host system to open
windows on the local system's display (generally, this is accomplished using
xhost on the local system; see the documentation for your X server for
details), and to set the DISPLAY environment variable on the host system
appropriately (if the local system runs UNIX, the value of DISPLAY should
be local-hostname:0.0 in most cases; again, consult your X server documentation).
wave uses many environment variables; they are listed in this
section roughly in order of importance. Many of them need not be set at
all, since wave uses reasonable default values in most cases. Those that
are set must be set on the host system.
- DISPLAY
- The name of the X server
and display you are using (see above). If you are using wave locally, or
if you are logged in via ssh, DISPLAY should be set automatically and should
not need to be changed.
- WFDB
- The database path (see setwfdb(1)
). If not
set, wave can find database files only in the builtin WFDB path. If you
edit annotation files and wish to reopen them later, be sure that the current
directory (in which wave writes any edited annotation files) is the first
directory in your database path.
- WFDBCAL
- The WFDB calibration file (see
setwfdb(1)
and wfdbcal(5)
). If not set, wave reads the builtin default
calibration file; if this is not accessible, wave may not scale signals
other than ECGs correctly.
- WAVEMENU
- The name of the analysis menu file (see
below); if not set, wave uses wavemenu if it exists in the current directory,
or $MENUDIR/wavemenu.def otherwise.
- SHELL
- The command interpreter used within
the Analysis Commands window; if not set, wave uses /bin/sh (the Bourne
shell). Other shell-related variables, such as PATH, are also significant
when wave is running commands within the Analysis Commands window.
- EDITOR
- The name of the text editor to be used for modifying the analysis menu
file and the log file. If not set, wave uses textedit (a simple editor
included with the XView toolkit).
- PRINTER
- The name of a printer to be used
for paper output; if not set, wave uses the default printer.
- PSPRINT
- The
command used to print PostScript data from the standard input; if not
set, wave uses `lpr -P$PRINTER'.
- TEXTPRINT
- The command used to print text from
the standard input; if not set, wave uses `lpr -P$PRINTER'.
- ANNTAB
- The name
of a file that contains custom annotation definitions (see `Resources', below,
for details). If not set, wave uses standard annotation definitions only.
The environment variables below are not needed unless the wave binary distribution,
or XView, has been installed in non-standard directories:
- HELPPATH
- The path
for XView spot help; if not set, wave initializes it to /usr/lib/help.
wave's own spot help is in $HELPDIR/wave, which is appended to the end
of HELPPATH by wave.
- HELPDIR
- The directory in which wave's help directory
is located; if not set, wave uses /usr/local/help.
- MENUDIR
- The name of
the directory that contains the default analysis menu file; if not set,
wave uses /usr/local/lib.
- RESDIR
- The name of the directory in which system-wide
default X11 resource files are kept; if not set, wave uses /usr/lib/X11/app-defaults.
XUSERFILESEARCHPATH, XAPPLRESDIR, and XENVIRONMENT are also used, together
with HOME and USER, to locate resource files (see X(1)
).
You can
control many aspects of wave's appearance and behavior by setting its resources.
If you are not familiar with this concept, refer to an introductory book
on using the X Window System, such as Quercia and O'Reilly's `X Window System
User's Guide'. Since wave is built using the XView toolkit, all of the resources
listed in xview(7)
can be used with wave. In addition, the following wave-specific
resources may also be set:
- Wave.AllowDottedLines
- This resource specifies
if wave is allowed to render dotted lines. wave normally draws annotation
marker bars as dotted lines, and may use dotted lines for other display
elements on black-and-white displays for clarity. Some X servers do not properly
render dotted lines, however; if you observe irregular or missing annotation
marker bars, change the value of this resource from True to False.
- Wave.Anntab
- This resource specifies the name of a file that contains a table of annotation
definitions. The environment variable ANNTAB can also be used to specify
this filename; the resource overrides the environment variable if both
are set. The file contains one-line entries of the form
15 % Funny looking beat
in which the first field specifies the (numeric) annotation code in the
range between 1 and ACMAX inclusive (see /usr/include/wfdb/ecgcodes.h for
a list of predefined codes and for the definition of ACMAX); the second
field (`%' in the example) is a mnemonic (used in annotation display and
entry), and the remainder of the entry is a description of the intended
use of the annotation code (which appears next to the mnemonic in the `Type'
field and menu of `Annotation Template' windows). Lines in the annotation
table that begin with `#' are treated as comments and ignored. It is not
necessary to specify an annotation table when editing an existing annotation
file unless previously undefined annotation types are to be added to it
during the editing process, although it is generally harmless to do so.
- Wave.Dpi
- This resource specifies the display resolution in dots per inch
in the form MMxNN, where MM is the horizontal resolution and NN is the
vertical resolution. Normally, the resolution is known to the X server,
and it is unnecessary to specify this resource. If your X server is misinformed,
wave's calibrated display scales will be incorrect; the best solution is
to specify the resolution using a server option such as the -dpi option
supported by MIT's X11 servers, since this will solve problems common to
any other applications that require calibrated scales as well. Not all
X11 servers support such an option, so this resource is available as a
work-around. The command-line option -dpi overrides the resource if both
are specified. (If you don't know the resolution, use xdpyinfo(1)
to determine
what your X server thinks it is. Then run wave, enable the grid display,
and measure the grid squares with a ruler. If they are larger than 5 mm,
the number of dots per inch returned by xdpyinfo is too large; adjust
the Wave.Dpi resource proportionally, and repeat the process until the grid
squares measure 5 mm in each direction.)
- Wave.GraphicsMode
- This resource
specifies the graphics mode used by wave; it can be overridden using the
-g, -m, -O, or -S options. The legal values are 1 (monochrome mode), 2 (overlay
greyscale mode), 4 (shared color mode), 6 (shared grey mode), and 8 (overlay
color mode).
- Wave.SignalWindow.{Grey|Color}.Element
- These resources specify
the colors to be used on greyscale or color displays. The `Color.*' resources
are used only if the display is color-capable and neither greyscale nor
monochrome mode has been specified. The defaults are:
Element | Grey | Color |
Background | white | white |
Grid | grey75 | grey90 |
Cursor | grey50 | orange
red |
Annotation | grey25 | yellow green |
Signal | black | blue |
- Wave.SignalWindow.Mono.Background
- In monochrome mode, the background is normally white, and all other display
elements are normally black. The reverse can be obtained by setting this
resource to black. (There is at least one server for which this fails.)
- Wave.Scope.{Grey|Color}.{Foreground|Background}
- These resources specify the
colors to be used in the Scope window on greyscale or color displays. The
Foreground color is used for the waveform and the time display; by default,
it matches the color used for signals in the signal window (see the previous
item). Some X servers do not allow the background color of the Scope window
to be set, because of the color map animation and stippled erasing techniques
used.
- Wave.Scope.Mono.Background
- This resource can be used to invert the foreground
and background of the Scope window when WAVE is running in monochrome mode.
This does not work for all X servers.
- Wave.SignalWindow.{Height_mm|Width_mm}
- These resources specify the preferred dimensions (in millimeters) for the
signal window. The defaults are 120 and 250 respectively.
- Wave.SignalWindow.Font
- This resource specifies the font used to display annotations and time marks
in the signal window. The default is fixed.
- Wave.TextEditor
- This resource
specifies the name of the text editor invoked by wave to permit you to
edit wave's log and analysis menu files. The default is textedit (the OpenLook
visual editor). You may override this resource by using the environment
variable EDITOR, which is also used by many other UNIX applications that
invoke editors.
Initial values for the settings controlled
from wave's View window can be specified using either X resources or command-line
options. Once suitable settings have been selected, use the `Save as new
defaults' button in wave's View window to record them in your .Xdefaults file.
In this section, the X resource name is specified first, and the command-line
option follows.
By default, all of the display options in the first group
are off (False); set any of these X resources to True to enable these options,
or use the command-line options to do so.
- Wave.View.Subtype (-Vs)
- Display annotation
subtyp fields.
- Wave.View.Chan (-Vc)
- Display annotation chan fields.
- Wave.View.Num
(-Vn)
- Display annotation num fields.
- Wave.View.Aux (-Va)
- Display annotation
aux fields.
- Wave.View.Markers (-Vm)
- Display annotation marker bars.
- Wave.View.SignalNames
(-VN)
- Display signal names along the left edge of the signal window.
- Wave.View.Baselines
(-Vb)
- Display baselines for any DC-coupled signals, and label the zero levels
and the units along the right edge of the signal window.
- Wave.View.Level (-Vl)
- While the pointer is in the signal window and any mouse button is depressed,
track the intersections of the marker bar with the signals and draw horizontal
marker bars across the signal window at the levels of these intersections.
The remaining resources and command-line display options correspond to the
menu buttons in wave's View window. The value of each resource, or the numeric
argument that immediately follows the command-line option, should match
the position of the desired menu choice, where the top item on each menu
is in position 0, the one below it is in position 1, etc. For example,
to set the initial amplitude scale to 5 mm/mV (the item at position 2 in
the `Amplitude scale' menu), add -Vv 2 to the command line, or Wave.View.AmplitudeScale:2
to the X11 resource database.
- Wave.View.TimeScale (-Vt)
- Set the time scale
(0: 50 mm/min; 1: 125 mm/min; 2: 250 mm/min; 3: 500 mm/min; 4: 12.5 mm/sec;
5: 25 mm/sec (default); 6: 50 mm/sec; 7: 125 mm/sec; 8: 250 mm/sec).
- Wave.View.AmplitudeScale
(-Vv)
- Set the amplitude scale (0: 1 mm/mV; 1: 2.5 mm/mV; 2: 5 mm/mV; 3: 10
mm/mV (default); 4: 20 mm/mV; 5: 40 mm/mV; 6: 100 mm/mV).
- Wave.View.SignalMode
(-VS)
- Set the choice on the `Draw' menu (0: all signals (default); 1: listed
signals only).
- Wave.View.AnnotationMode (-VA)
- Set the choice on the `Show annotations'
menu (0: centered (default); 1: attached to signals; 2: as a signal).
- Wave.View.TimeMode
(-VT)
- Set the choice on the `Time display' menu (0: elapsed (default); 1:
absolute; 2: in sample intervals).
- Wave.View.GridMode (-VG)
- Set the choice
on the `Grid' menu (0: none; 1: 0.2 s; 2: 0.5 mV; 3: 0.2s x 0.5 mV (default)).
In addition to the usual ways of setting X resources, it is possible to
set any of those listed above, as well as any of the generic XView resources,
by using the -xrm or -default options on the command line when starting wave.
For example, you can set the background color of the signal window using
a command such as
wave -r 100s -xrm Wave.SignalWindow.Color.Background:lightblue
By specifying two or more record names,
separated by `+' characters, in the command-line argument that follows `-r' (see
above), you may open separate WAVE signal windows (processes) for each
record. These processes are almost completely independent: from any signal
window, you may navigate within the record, change display settings, edit
annotations, run external analysis programs, quit the process, etc., without
affecting any other signal windows.
For example, you may open two signal
windows for the same record by:
wave -r 100+100 -a atr
You can now move about the record freely in either window. This facility
makes it easy to compare different segments of the record. Note that whenever
two or more windows are displaying the same set of annotations, as in this
case, only one should be editing the annotations at any given time.
The
window associated with the last record named on the command line has a
special status: it is designated the master signal window, and an extra
button (labelled `Sync') appears at the top of this window. Clicking on this
button causes all of the other signal windows to be redrawn so that the
times shown in their lower left corners match that in the master signal
window. (Note, however, that if you have quit a signal window from the
middle of the list, any signal windows from earlier in the list will no
longer respond to sync requests.)
By default, all command-line arguments
apply to all signal windows. You may specify an argument that is to apply
to only one signal window, however, by prefixing the argument with `+n/',
where n is the signal window number. (The first signal window, corresponding
to the first record named on the command line, is signal window number
0; the next is number 1, etc.)
This facility has many applications. For
example, you may wish to open two copies of the same record, with two different
annotators:
wave -r 100+100 -a +0/atr +1/qrs
In this case, record 100 is opened in two windows, with annotator `atr' in
window 0 and annotator `qrs' in window 1. (The `-a' option applies to both windows
since it does not have a `+n/' prefix.)
As another example, you may wish to
discuss a record with colleagues at other locations:
wave -r 200+200+200 -a qrs +0/-display +0/atlantic.bigu.edu:0 \
+1/-display +1/pacific.widget.com:0
Here, record 200 is opened in three windows. Window 0 is opened on display
0 of atlantic.bigu.edu, window 1 on display 0 of pacific.widget.com, and window
2 (the master window) on the local display. (For this to work, your colleagues
must first allow your computer to open windows on their displays, typically
using xhost. See xview(7)
for information about the -display option. Notice
that the `+n/' prefix must be attached to both the `-display' option and to
its argument in order to apply both of these arguments to the same signal
window.) Your colleagues can freely move about the record, but you can direct
the discussion at any time by using the Sync button in your signal window.
In a case such as this one, anyone can enable editing; you should do so
only after making sure that no one else has. Once you have saved your work
(by selecting `Save' from the File menu), your changes become visible to
your colleagues if they reload the annotations (by clicking on `Reload' from
the Load window).
As a final example, the MIMIC Database includes both high-resolution
waveform records and medium-resolution (roughly 1 sample per second) computed
measurement records. You may view both of these at the same time using
a command such as:
wave -r 237+237n -a all
Typically, you will wish to view the high-resolution and low-resolution data
at different time scales. Although wave attempts to choose reasonable defaults,
you can adjust the scales independently if you wish:
wave -r 237+237n -a all +1/-Vt +1/2
If you use wavescript or wave-remote to control the master signal window
(this happens by default unless you use the -pid option of these programs
to control a different signal window), the other signal windows are kept
synchronized with the master window.
Note that you cannot increase the number
of signal windows in a group once you have started a wave process group,
although you can run more than one process group at a time if you wish.
wave uses a simple menu file to allow you to set up analysis
options. Each line in the file corresponds to a button in the Analyze window
(except for empty lines and lines that begin with `#', which are ignored).
Within each line, the syntax is label<tab>action, where <tab> is one or more
tab characters. The label field is used to identify a command button in
the Analyze window, and the action field is any command acceptable to your
shell. button-label and action may include spaces if needed; if necessary,
a `\' may be used at the end of a line to indicate that it is continued on
the next line. Before the command is executed, wave replaces certain tokens
with appropriate strings; these include:
- $RECORD
- The name of the current
record.
- $ANNOTATOR
- The name of the current input annotator.
- $START
- The currently
selected `start analysis' time.
- $END
- The currently selected `end analysis' time.
- $DURATION
- The time interval between $END and $START.
- $LEFT
- The time corresponding
to the left edge of the signal window.
- $RIGHT
- The time corresponding to
the right edge of the signal window.
- $WIDTH
- The time interval between $RIGHT
and LEFT.
- $SIGNAL
- The currently selected signal number (as shown in the
Analyze window).
- $SIGNALS
- The current signal list (as shown in the Analyze
window).
- $LOG
- The name of the current log file (as shown in the Log window).
- $WFDB
- The WFDB path (from the Load window).
- $WFDBCAL
- The name of the WFDB
calibration file (from the Load window).
- $TSCALE
- The time scale, in mm/sec.
- $VSCALE
- The amplitude scale, in mm/mV.
- $DISPMODE
- The annotation display
mode (0: annotations displayed in center, no marker bars; 1: annotations
displayed in center, long marker bars; 2: annotations attached to signals,
no bars; 3: annotations attached to signals, short bars; 4: annotations
displayed as a signal, no bars; 5: annotations displayed as a signal, long
bars)
- $PSPRINT
- The command for printing PostScript data from the standard
input, as specified in the Print Setup window.
- $TEXTPRINT
- The command for
printing text from the standard input, as specified in the Print Setup
window.
- $URL
- The URL specified by the most recently selected link.
Other
tokens that begin with `$' are passed to the shell unchanged.
The default
menu file includes the following lines (among others):
Mark QRS complexes | sqrs -r $RECORD -f $START -t $END -s $SIGNAL |
Calibrate | calsig
-r $RECORD -f $START -t $END -s $SIGNALS |
Extract segment | snip -i $RECORD -f $START
-t $END -n n_$RECORD \ |
| -a $ANNOTATOR |
List annotations | rdann -r $RECORD -a $ANNOTATOR
-f $START -t $END |
List samples | rdsamp -r $RECORD -f $START -t $END -s $SIGNALS |
Print chart | echo $RECORD $START-$END | \ |
| pschart -a $ANNOTATOR -g -l -R -s $SIGNALS
- | $PSPRINT |
Print full disclosure | echo $RECORD $START-$END | \ |
| psfd -a $ANNOTATOR
-g -l -R -s $SIGNALS - | $PSPRINT |
Whenever the pointer is in
the signal window, the normal arrow pointer is replaced by a crosshair
pointer. At these times, the numeric keypad and several of the function
keys may be used for many annotation editing and display operations, and
the normal alphanumeric and punctuation keys can be used to select single-character
annotation mnemonics (displayed in the Annotation Template window). `Num
Lock' must be off if you wish to use the keypad for editing operations.
Some of the function and numeric keypad commands work on Sun keyboards
only; in these cases, alternate keyboard commands for use with PC and
other keyboards are shown in parentheses. Most of these alternate commands
also work on Sun keyboards.
- <Help> (<F1>)
- Open XView spot help for the item
under the pointer. (Unlike most of the other keyboard commands, this command
is available at any time, not only when the pointer is in the signal window.)
- <left arrow>
- Select the annotation to the left of the pointer. (Click left
to do this using the mouse. These actions also work when the pointer is
in the scope window.)
- <right arrow>
- Select the annotation to the right of
the pointer. (Click right to do this using the mouse. These actions also
work when the pointer is in the scope window.)
- <up arrow> Move the selected
annotation up one signal (i.e.,
- decrement its chan field). This command works
in multi-edit mode only (enter multi-edit mode by choosing `attached to signals'
from the `Show annotations' menu in wave's View window).
- <down arrow>
- Move the
selected annotation down one signal (i.e., increment its chan field). This
command works in multi-edit mode only.
- keypad <5> (<F2>)
- Insert an annotation
at the current position of the pointer. (Click the middle button to do
this using the mouse. Annotation editing must be enabled for this action
to be successful.)
- keypad <=> (<F3>)
- Move the pointer toward the left.
- keypad
<*> (<F4>)
- Move the pointer toward the right.
- <Copy> (<F6>)
- Copy the selected annotation
to the Annotation Template.
- <Find> (<F9>)
- Search forward.
- <ctrl><Find> (<ctrl><F9>)
- Search
backward.
- <End> (<shift><F9>)
- Advance to the end of the record.
- <Home> (<ctrl><shift><F9>)
- Move to the beginning of the record.
- <PgDn> (<F10>)
- Advance half a screen.
- <ctrl><PgDn>
(<ctrl><F10>)
- Advance a full screen.
- <PgUp> (<shift><F10>)
- Move back half a screen.
- <ctrl><PgUp> (<ctrl><shift><F10>)
- Move back a full screen.
- <Enter> (<Return>)
- (Only if
a link annotation has been selected.) Show the external data specified
by the link using a Web browser; start the Web browser first if necessary.
Under SunOS, once you have opened the Analyze window or have selected
Print from the File menu, do not attempt to suspend wave (for example,
by typing control-Z in the controlling terminal window). Under these circumstances,
wave may exit immediately (without quit confirmation) and any unsaved edits
may be lost. This problem is the result of a bug in the XView termsw package
used for the Analysis Commands window. To avoid this bug, always run wave
in the background under SunOS. The Solaris 2.x and Linux versions of the
XView library do not have this bug.
If wave opens with an empty signal window,
this may mean that the X server's backing store is disabled. If possible,
enable backing store and restart the X server. (Using XFree86 4.x, backing
store can be enabled by inserting the line `Option "backingstore"' in the
`Device' section(s) of the XF86Config-4 file. If the X server is normally
started by a display manager such as xdm, close all windows and restart
the server with <ctrl><alt><backspace>. Otherwise, log out, log in, and restart
the X server manually if necessary.)
If this doesn't solve the problem, use
any of wave's navigation controls, or resize the signal window, to make
the signals visible. On some 24-bit displays, this problem may be the result
of an X server bug, and these methods will work around the problem. On
some of these displays, text in the signal window may be invisible using
overlay graphics mode; if this happens, use the -S option.
No more than one
piped record (see the WFDB Programmer's Guide) can be viewed in a single
invocation of wave. If the signal file is a pipe, it is possible only to
search forward through it (although wave caches several of the most recently
displayed windows, which can be reviewed in any case). Using the `>' button
to move by half a frame does not work properly with piped input, nor does
changing the display scales, since these actions require rereading the
signals.
There appears to be a subtle incompatibility between XView-based
applications such as wave and at least some X servers. The symptom of this
problem is that wave's View panel may be blank, and many warning messages
from the notifier may appear in the controlling terminal window. This problem
appears to occur only when all of the following are true: the X server
is running on a multi-head display with Xinerama enabled, the user does
not have root privileges, a .Xdefaults file exists, and wave or another
XView application has run at least once since the X server was started.

WAVE User's Guide
wave currently runs under Linux, Solaris,
and SunOS. It should be easily portable to any POSIX-compliant OS that can
support X11 and XView. If you would like to use wave on a system other than
those listed above, you will need to port XView to your system first (or
purchase a commercial port if one is available). Sources for XView are
supplied on our CD-ROMs that include wave, and are also available from PhysioNet
(www.physionet.org, where the sources for wave itself are also available),
metalab.unc.edu, tsx-11.mit.edu, and their mirrors. We cannot offer assistance
in porting XView; if you wish to try this, you are on your own. If you successfully
port the cmdtool terminal emulator application included in the XView sources,
we will assist you in porting wave (this is much simpler than the XView
port).
The second edition of the MIT-BIH Arrhythmia Database CD-ROM contained
an earlier version of wave (for Sparc SunOS only) that lacked many of the
features described here. Refer to the documentation included on that CD-ROM
for details.
Beta (test) versions of gtkwave are available for Linux and
MS-Windows. It should be straightforward to recompile gtkwave sources for
any other environment in which the GTK+ toolkit and the WFDB library are
available.
