Analysis Functions 193Chapter 13 Edit menu commandsOne of the most useful features in the Biopac PRO software is the ability to edit and work with data by cuttingsections and copying sections from one window to another. The Edit menu contains options that allow you to workwith data much as a word processor lets you work with text.UndoWith some exceptions, the Undo command will undo the last command carried out by Biopac Student Lab PROsoftware. This allows you to restore data that was unintentionally deleted or modified. The Undo command appliesnot only to editing commands, but also to transformations (such as digital filtering and mathematical operations).When Undo is enabled, it will list the command it can undo, such as “Undo Paste.” When a command can’t bereversed, the Undo option will read Can’t undo.Can’t UndoThere are some exceptions to the Undo command, and you should be aware of them before you choose to use anycommand. The following commands cannot be undone:‣ Display options (i.e., changing the horizontal scale or changing the color of a waveform) cannot beundone, since they are easier to manipulate and less drastic than cutting data out of a waveform. Ifyou modify the screen scale (or other display parameters) you will still be able to undo your latestdata modification, which is much more difficult to recover than a screen parameter change.‣ Clear All cannot be undone. It is a good idea to make backup files before performing any editing,especially when using this command.‣ Remove Waveform cannot be undone. It is a good idea to make backup files before performing anyediting, especially when using this command.‣ Insert Waveform cannot be undone, but selecting the inserted channel and choosing RemoveWaveform from the Edit menu effectively undoes this operation.‣ Rewind button cannot be undone. TIP If you accidentally remove a waveform or choose clear all, one way to recover the datais to close the file without saving the changes. The data file can then be reopened as it waswhen it was last saved; any changes made since it was last saved will be lost.
