Parameter selection for moving average smoothing (A) A $4$-s piece of an example trajectory for a fish of age $21$ dpf for a moving average window width of 1, 5, 10, 60, and 100 frames. The blue arrow indicates the direction of movement of the animal, and yellow arrows indicate the direction of total acceleration for some selected frames. Gray dots show the coordinates of the original trajectory. (B) Probability of focal animal turning to the right when second animal is in different positions in space for the corresponding values of the smoothing parameter (results are obtained from the full trajectory). (C) Same as B but for randomized control data.
