Analysis with idSocial. The following idSocial methods have been used to analyze trajectories (from top left to bottom right): Interindividual distance, relative position, turning probability (the probability of turning toward a conspecific), turning probabilities for relative positions, turning probability for groups (the probability of turning toward a specific number of conspecifics in a given configuration), acceleration probability (the probability of speeding up/slowing down depending on the position of a conspecific in front/at the back), acceleration probability for relative positions, probability of having a certain number of close neighbors, and speed and turning angle.
