Table 1. Motility parameters by quadrant.

Quadrant 1:Velocity is high Meandering Index is low “Active migration, returns to origin”	Quadrant 2: Velocity is high Meandering Index is high “Directional, sustained motility”
Quadrant 3: Velocity is low Meandering Index is low “Low motility”	Quadrant 4: Velocity is low Meandering Index is high “Non-sustained motility”
