File Press the right mouse button to bring up the File menu, which
includes:
Load... Select this item to bring up the Load window; change
the `Record' or `Annotator' fields in the Load window
in order to load a different record or annotation file.
The initial values of these fields are obtained from
the -r and -a options on the command line. If the
`Annotator' field is empty, no annotations are loaded.
Save Select this item to force your edits to be written to
disk files. (This is done automatically after every
20 edits, any time the record or annotator is changed,
and upon exiting WAVE.)
Print Select this item to print the contents of the ECG
window in chart recorder format (after saving any
edits). This is accomplished by spawning a `pschart'
process, so you need not wait for the output before
continuing. Output from multiple print requests
appears in the order in which the requests were made.
Analyze... Select this item to bring up the Analyze panel and the
Analysis commands window; use the buttons in the panel
to analyze the record, or type a command directly into
the Analysis commands window. The names of most of the
buttons and their assigned actions are read from a menu
file (by default, /usr/local/lib/wavemenu.def; this
may be overridden by setting the environment variable
WAVEMENU to the name of a different file). The buttons
are usually configured to perform various analysis
functions on the current record; read the default menu
file for details.
Log... Select this item to bring up the Log window. Change
the `Log file name' field to load a log file; enter
text to be recorded in the log file in the
`Description' field. Record an entry by pressing the
`Save' button, or dismiss the window without logging
the entry by pressing `Cancel'. Review the entries
by pressing `Review log'; each entry will be displayed
for 5 seconds unless you press `Pause' (disabled except
while reviewing the log). Each entry contains the
record name, the times shown at the lower left and
right corners of the ECG window, and the contents of
the `Description' field. Log files may be used as
command scripts for `pschart'. You may write to as
many log files in a single session as you choose, and
you may accumulate entries from multiple sessions in a
single log file.
View... Press the left mouse button to bring up the View window, which
includes:
Show: Select one or more of these items in order to enable
or disable optional elements of the ECG display.
Time scale: Press the right mouse button to view the list of
available time scales; drag the pointer to the
desired scale and release the right mouse button.
Amplitude scale:
Press the right mouse button to view the list of
available amplitude scales; drag the pointer to the
desired scale and release the right mouse button.
Draw: Press the right mouse button to select either `all
signals' or `listed signals only'. If you choose
`listed signals only', signals are displayed in the
order specified in the signal list on the `Analyze'
panel, and any signals not included in the list are
not displayed.
Grid: Press the right mouse button to view the list of
available grid types; drag the pointer to the
desired type and release the right mouse button.
Undo changes Select this item to restore the View window indicators
to match the current state of the ECG window.
Redraw Select this item to apply any changes you have made
and to dismiss the View window.
Edit Press the right mouse button to bring up the Edit menu, which
includes:
Allow editing Select this item if you wish to make changes in the
annotation file.
View only Select this item if you do not wish to edit the
annotation file any longer. By default, editing is
disabled when WAVE is started up.
Properties Press the right mouse button to bring up the Properties menu,
which includes:
Signals... Select this item to view information about the ECG
signals in the current record.
Annotations... Select this item to view a summary of the contents of
the current annotation file.
About WAVE... Select this item to view information about the version
number and installation date of this version of WAVE.
< Search Search backwards, beginning with the annotation that
immediately precedes the earliest annotation currently
displayed, for an annotation that matches the entry in the
"Search for" field of the Find window (see below). The display
is redrawn, roughly centered on the matching annotation.
<< Skip backwards by an amount equal to the duration of the
signals currently displayed (i.e., a full screen).
< Skip backwards by one-half screen.
Find... Press the left mouse button to bring up the Find window, which
includes:
Start time: The value of this item is the time shown in the lower
left corner of the ECG window. Change it in order to
view another part of the record. (Time can be entered
in h:m:s format, with hours or hours and minutes
omitted, or in sNNNNN format, in which NNNNN is a
number of sample intervals from the beginning of the
record. Time is always rounded down to an even
multiple of one second, and is displayed in m:s or
h:m:s format irrespective of the input format once the
display is refreshed.)
End time: Similarly, this item's value is the time shown in the
lower right corner of the ECG window. Change it in
order to view another part of the record. If you
change both the Start time and the End time fields
without pressing RETURN in between, only the last
change is effective. To change the duration of the
ECG window, select the View window (see above) and
change the time scale.
Search for: This entry is initially empty. Enter a string to
specify a search target for the "< Search" and
"Search >" buttons. The string should match an
annotation or marker mnemonic, signal quality code,
rhythm, comment, or other text string, or one of:
*v to match any ventricular ectopic beat
*s to match any supraventricular ectopic beat
*n to match any other beat type
* to match any annotation or marker
. to match a deletion made during this edit
> Skip forwards by one-half screen.
>> Skip forwards by a full screen.
Search > Search forwards, beginning with the annotation that
immediately follows the last annotation currently displayed,
for an annotation that matches the entry in the "Search for"
field of the Find window (see above). The display is redrawn,
roughly centered on the matching annotation.
Help This button pops up a panel containing buttons that name
several topics for which extensive on-line help is available.
Choosing a topic allows you to browse through the associated
help file in a scrollable text window.
Quit WAVE exits when you press this button, after saving your edits
if any. If your input file would be overwritten as a result of
saving your edits, it is first renamed by appending a `~' to
the annotator name. If you have entered annotations but have
not specified an annotator, the name by which you invoked this
program (normally, `wave') is used for the annotator name.
