Define Counting Frame

This command allows you to define the XY size of the counting frame used with the Fractionator, and Optical Fractionator probes. The counting frame disappears immediately after it has been defined. It is only displayed during the execution of the probes that use it.

 

If the counting frame is not visible in your tracing window, it may be larger than the current field of view.

  • Enter new values for Size (side length for the square shape) or for X and Y (for the rectangle shape).

OR

  • Drag the sides of the frame with the mouse. The dimensions are updated in the Define Counting Frame window.
ClosedChanging the shape from a square (default) to a rectangle
  • Place the mouse over the frame, right-click and select Force Square.
