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.
