Track workflow: Detection

Procedure

  1. Click a few worms to define a size range. The worms are displayed with an overlay model.
  2. The detection parameters are set by example based on the worms you clicked. See The Detection panel to learn about the parameters.
  3. Click the button to obtain a preview of the detected worms in the window.
    • If you're not satisfied with the results, click more worms in the window to modify the parameters.
    • If you're satisfied, start tracking.
ClosedRemoving the model of a worm that you don't want to track
  1. Select the icon in the toolbar.
  2. Click the unwanted worm to select it.
  3. Press the Delete key.
ClosedManually adding a worm that wasn't detected

Sometimes a worm fails detection because its shape does not conform to the detection parameters or it is overlapping itself.

Rather than reset the parameters, trace the worm manually:

  1. Click the icon
  2. Click along the worm's centerline from head to tail to draw the worm.
  3. Right-click at the tail to end the drawing. An green overlay model is placed over the worm.

If you right-click away from the worm, even slightly, the model will be incorrect. See an example of an incorrect model here:
