Data from: Selective social interactions and speed-induced leadership in schooling fish

Experimental datasets for the manuscript: Puy, A., Gimeno, E., Torrents, J., Bartashevich, P., Miguel, M. C., Pastor-Satorras, R., & Romanczuk, P. (2024). Selective social interactions and speed-induced leadership in schooling fish. Proceedings of the National Academy of Sciences, 121(18), e2309733121. The datasets provide trajectories of fish. There are 2 recordings with N=39 fish (60 minutes duration) and 6 recordings with N=8 fish (30 minutes duration). The columns are as follows: Time [frame]: Time of the trajectory in frames. X_0 [px]: Position in the x-coordinate in pixels of the trajectory of individual 0. Y_0 [px]: Position in the y-coordinate in pixels of the trajectory of individual 0. X_1 [px]: Position in the x-coordinate in pixels of the trajectory of individual 1. Y_1 [px]: Position in the y-coordinate in pixels of the trajectory of individual 1. ...
