Myotonia Congenita-Associated Mutations in Chloride Channel-1 Affect Zebrafish Body Wave Swimming Kinematics
Figure 1
Illustration of quantitative measurements of zebrafish body waving.
The fish body (blue curve) is characterized at twenty body locations (red dot). L is the body length, T is the distance between the tail and the center of fish body, is the angular change between two consecutive body locations. Given the coordinates of two consecutive body locations [x(i), y(i)] and [x(i+1), y(i+1)], the angular change is defined as
