annotations in the center of the signal window.
If you select `attached to signals', each
annotation appears near the signal specified by
its `chan' field.  If you select `as a signal',
WAVE draws a signal derived from the `num' fields
of any annotations in the window, in place of the
standard annotation display.  Changes are not
effective until the signal window is redrawn.
#

:view.overlap
Use this menu button to control the display of
long annotation text.  By default, WAVE will
truncate the display of annotation text that is
longer than 3 characters, if it would overlap
the display of another annotation.  Choose
`allow overlap' if you wish to have WAVE display
as much of the text as will fit in the screen
(text may still be truncated at the right edge
of the signal window).  Changes are not effective
until the signal window is redrawn.

The full text (up to 80 characters) of the
currently selected annotation, if any, appears in
the footer of the signal window (at left).  Move
the pointer just to the left (or right) of an
annotation and click right (or left) to select
it.
#

:view.time_display
By default, WAVE displays elapsed time from the
beginning of the record in hh:mm:ss format.
Use this control to select display of absolute
time (if defined for the record), or to display
time in sample intervals.  If you select absolute
time display, you may enter absolute times in
the Find and Analyze panels.  Changes are not
effective until the signal window is redrawn.
#

:view.grid
Use this menu button to select a grid style.
Changes are not effective until the signal window
is redrawn.
#

:view.undo
This button cancels any changes you have made to
the View window settings and restores the
indicators to reflect the current settings.
#

:view.redraw
This button causes WAVE to accept any changes
you have made in the View panel.  Pressing
the `Redraw' button dismisses the View window
and refreshes the signal window.
#

:view.save_as_new_defaults:%sec:resources%
This button causes WAVE to record the current
View panel settings in your .Xdefaults file
(at the same time erasing any comments in
that file).  These settings become the new
defaults for your future WAVE sessions.

:edit:%sec:edit-menu%
This button brings up the Edit menu, which
allows you to specify if annotation editing
is to be allowed or forbidden.  By default,
editing is forbidden when WAVE starts up.
#

:edit.allow_editing
This selection allows you to make changes to the
annotation buffer.  By default, editing is
forbidden when WAVE starts up.
#

:edit.view_only
This selection disallows annotation editing.
You may still edit `<', `:', and `>' markers.
#

:prop:%sec:prop-menu%
This button brings up the Properties menu,
with selections for obtaining information
about the current signal and annotation files
and about this version of WAVE.
#

:prop.signals:url_view /usr/local/help/html/wag/wfdbde-1.htm
This selection pops up a window containing
information about the signals of the current
record, obtained by running `wfdbdesc'.
#

:prop.annotations:url_view /usr/local/help/html/wag/sumann-1.htm
This selection pops up a window containing
a summary of the contents of the annotation
buffer, obtained by running `sumann' (after
saving any edits).
#

:prop.wave
This selection pops up a window containing
the version number and installation date of
this version of WAVE.  This window may also
contain news about recent changes in WAVE.
#

:<search
This button recenters the signal window on the
previous occurrence of an annotation or marker
that matches the entry in the `Search for' field
of the Find window, if any.  If no match is found,
a notice is posted, but the signal window is not
recentered.

If the `Search for' field is empty, any annotation
or marker will be counted as a match.
#

:<<
This button scrolls the signal window towards the
beginning of the record, by an amount equal to the
width of the signal window (i.e., a full screen).
#

:<
This button scrolls the signal window towards the
beginning of the record, by an amount equal to
half of the width of the signal window.
#

:find:%sec:find-window%
This button opens a window that allows you to
specify what portion of the current record should
be displayed next.  You may set a specific start
or end time, or you may specify an annotation to
be searched for by the "< Search" and "Search >"
buttons.
#

:find.start_time
Specifies the time of the sample shown at the left
edge of the signal window, in the format specified
by the `Time display' item in the View window.  Go
to any other part of the record by entering the
time in this field.

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.
#

:find.end_time
Specifies the elapsed time from the beginning of
the record to the sample shown at the right edge
of the signal window, in hours, minutes,
and seconds.  Go to any other part of the record
by entering the time in this field.

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.
#

:find.search_for
Specifies a target for the "< Search" and "Search
>" buttons.  Changing this field causes an
immediate forward search.  The contents of this
field should match an annotation or marker
mnemonic, signal quality code, rhythm, comment, or
other text string, or one of the following:

  *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
#

:find.more_options:%sec:search-template-window%
This button clears the contents of the "Search for"
field and opens the Search Template window.
#

:>
This button scrolls the signal window towards the end
of the record, by an amount equal to half of the

of the record, by an amount equal to the width of
the signal window (i.e., a full screen).
#

:search>
This button recenters the signal window on the next
occurrence of an annotation or marker that
matches the entry in the `Search for' field of the
Find window, if any.  If no match is found, a
notice is posted, but the signal window is not
recentered.

If the `Search for' field is empty, any annotation
or marker will be counted as a match.
#

`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 tilde
(`~') to its 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.
#

:main_panel
This is the main control panel of WAVE.
Move the pointer onto any of the controls
and press the HELP key for further
information.
#

:canvas
This is the signal window, in which signals and
annotations are displayed.  For information
about using the mouse in this window, press
the `Help' button and select the `Annotation
Editing' topic from the Help window.
#

:annot.type:%fig:annotation-template%
This field specifies the type of annotation
to be inserted.  It may be changed by selecting
a new value from the pull-down menu, by typing
the mnemonic while the pointer is within the
signal window, or by selecting an existing
annotation and pressing the <Copy> or <F6>
keys.
#

:annot.text
This field specifies the contents of the
optional annotation `aux' field.  It may be
changed by typing into it directly or by
selecting an existing annotation and pressing
the <Copy> or <F6> keys.  In most cases, it
should be empty, but it must be filled in for
rhythm and certain other non-beat annotations.
When the annotation is written, WAVE prefixes
the required byte count to this field before
transferring it to the `aux' field.
#

:annot.subtype
This field specifies the contents of the
annotation `subtyp' field.  In most cases,
it should be 0; legal values range from
-128 to +127.

This field specifies the contents of the
annotation `chan' field.  In most cases,
it should be 0; legal values range from
-128 to +127.
#

:annot.num
This field specifies the contents of the
annotation `num' field.  In most cases,
it should be 0; legal values range from
-128 to +127.
#

:annot.change
This button changes all annotations between
the `<' and `>' markers (the Start and End
times on the Analyze panel) to match the
annotation template.
#

:annot.dismiss
This button makes the Annotation Template
window disappear (until the left mouse
button is pressed while the pointer is
within the signal window).
#

:level.show
Choose how time and signal levels are
displayed in the Level window using this
menu.  Physical units are seconds (time)
and units defined in the record's header
file for each signal.  WFDB units are
sample intervals and analog-to-digital
converter units (adu).  In relative mode,
all measurements are shown as differences
between the current location and the
reference location.
#

:level.time
This area shows either the time of the
measurements shown in the rest of the
window (if absolute mode is selected),
or the time interval from the reference
mark (if relative mode is selected).
#

:level.signame
The names of the signals appear in the
left column of the Level window.
#

:level.value
The levels of the signals at the chosen
time are indicated in the center column.
#

:level.units
The third column indicates the physical
units of each signal.  If an asterisk
(*) appears next to any units, this
indicates that the signal has not been
calibrated.
#

:level.dismiss
This button closes the Level window.
#

:scope_panel:%sec:scope-window%
This panel contains controls for the
Scope window, which displays the signal
indicated by the Signal control in the
Analyze window.
#

:scope_panel.speed
This slider controls the playback speed.
Click left on the slider and drag it
to the desired position -- lower to
reduce speed, higher to increase speed.
#

:scope_panel.dt
This field specifies the interval
from the left edge of the scope window
to the annotated sample, in seconds.
Negative values may be used to shift the
left edge of the scope window past the
annotated sample.

Drag the resize corners to change the
interval between the left and right
edges of the scope window.
#

:scope_panel.<<
This button displays frames
continuously in reverse order.
Use the Pause button to interrupt
the display.  The display stops when it
reaches the beginning of the record,
an index mark (`:'), or the `<' marker.
#

:scope_panel.<
This button displays the previous
frame.
#

:scope_panel.pause
This button freezes the scope display.
It also forces the signal window to be
redrawn, roughly centered on the time
shown at the bottom of the scope window.
#

:scope_panel.>
This button displays the next frame.
#

:scope_panel.>>
This button displays frames
continuously in normal order.
Use the Pause button to interrupt
the display.  The display stops when it
reaches the end of the record,
an index mark (`:'), or the `>' marker.
#

:scope_canvas:%sec:scope-window%
This is the scope window, which displays the
signal indicated on the Analyze panel.  The
scales match those in the signal window (use
the controls in the View panel to set them).
Annotations trigger the scope. If annotations
in the signal window are attached to signals,
only those attached to the selected signal
trigger the scope. Click left or right to
single-step, middle to interrupt, ctrl+left
or ctrl+right to resume continuous display.
Change dt by ctrl+middle while pointing to
the desired location of the trigger point
within the window.  The left, up, and right
arrows on the numeric keypad emulate the
mouse buttons.
