WAVE logs are text files, in the format used by `pschart' and `psfd' script files. Typically, logs contain notes about interesting sections of one or more records. Each entry (line) in a WAVE log contains a record name, a time reference, and a comment. Using the `Log ...' window (accessed from the `File' menu of WAVE's main control panel), you may create or review logs, and add, modify, or delete entries in them. Within the WAVE menu, the name of the current log file can be represented as `$LOG'; this feature may be used to write WAVE extensions that extract or print segments of interest. When the log panel is first opened, most of its controls are disabled. You must specify a name for the log before you can use any of these controls. Do so by typing the name into the `File:' field; press RETURN to tell WAVE to accept the name. If the log exists already, WAVE reads its contents and shows you its first entry. If the log does not exist, WAVE creates an empty log with the name you have chosen. The other controls are enabled as appropriate (for example, the `Delete' button is not enabled unless there is an entry to delete). The `Description:' field contains the description associated with the current log entry. The buttons of the log panel are: Load WAVE reads the log file into memory, after saving the current contents as a backup file if any changes were made since it was most recently loaded. Use this button to read a log file generated by another process, such as a WAVE analysis menu button. Add WAVE adds an entry containing the record name and the contents of the description field to the log file. If an annotation or marker within the signal window has been selected (i.e., if it is shown marked with a box), WAVE records the time of that annotation in the log entry; when the entry is redisplayed, WAVE selects the same annotation again. Otherwise, WAVE records the times in the lower left and right corners of the signal window. Replace WAVE replaces the description attached to the current log entry with the current contents of the description field. It does not create a new entry (use the `Add' button for that purpose). Delete WAVE deletes the current entry from the log, and displays the next entry if it exists. Edit This button is currently non-functional. |< WAVE shows the first log entry. << WAVE reviews each entry in the log file in reverse order, pausing 5 seconds between entries. While a review is in progress, only the Pause button is enabled. < WAVE shows the previous log entry. Pause WAVE stops the log review that was begun by the `<<' or `>>' button. This button is disabled unless a review is in progress. > WAVE shows the next log entry. >> WAVE reviews each entry in the log file, pausing 5 seconds between entries.
