Track workflow: Repair

Sometimes WormLab incorrectly identifies the head as the tail and vice-versa after a worm emerges from an omega bend or fold.

Correcting this problem:

1. Click a worm to select it.
2. Select Entire track OR To end of track.
   • Entire track: Swaps the head and tail in all frames for the selected worm.
   • To end of track: Swaps the head and tail from the current frame displayed until the end of track for the selected worm.
3. Click Swap head/tail.

• Select This frame to remove the detected worms from the current frame.
• Select All frames to remove the detected worms from all frames.

1. Enter the track numbers to join:
   • If the numbers are consecutive, use a dash (ex: 1-20).
   • If the numbers are not consecutive, use commas.
2. Click Join Tracks. WormLab joins the secondary worm track and the original, primary worm track. The newly created worm track is assigned the original, primary track number.

Join Tracks only connects from the end of a track to the beginning of another track.

To connect a track that is interrupted at frame "n" and resumed at frame "n+x" to tracks generated between frame "n" and frame "n+x":
1. Use Split Tracks to "end" the interrupted track 1 at frame "n"
2. Use Join Tracks to connect the interrupted track to the other tracks.

1. Use the slider to navigate to the desired frame.
2. Click a worm to select its track.
3. Click Split Tracks .
4. WormLab splits the original (primary) track and creates a new (secondary) track for the worm.

Click a worm then click the Delete track button to delete a worm model and its data.

Use the Undo button to undo the last operation:

• After deleting a track: Restore the track and the data.
• After joining or splitting: Return to previous state.
