 # Using the [[Documentation/{{documentation/version}}/Modules/Editor#Change Label|Change Label]] effect, change the background color to black.
 # Once the background label has been changed, look through each slice for leaked pixels.
-# To fix leaked pixels, use the [[Documentation/{{documentation/version}}/Modules/Editor#Paint|Paint]] tool to erase extra pixels from the label map. After looking through each slice for leaked pixels, the label map should accurately represent your tumor.
+# To fix leaked pixels, use the [[Documentation/{{documentation/version}}/Modules/Editor#Paint|Paint]] tool to erase extra pixels from the label map. Another way to edit your label map is to apply the [[Documentation/{{documentation/version}}/Modules/Editor#Undo/Redo|Undo/Redo]] tools. Using the undo, the watershed can be undone and the original label map can be edited. The redo tool can reapply an updated version of the Watershed from Markers effect. After looking through each slice for leaked pixels, the label map should accurately represent your tumor.
