Experimental and simulated data from "Swimming speed of schooling fish controls social interaction strength in open-loop immersive virtual reality"

Experimental data and data from numerical simulations from "Swimming speed of schooling fish controls social interaction strength in open-loop immersive virtual reality", with authors Ramón Escobedo, Justine Reynaud, Stéphane Sanchez, Clément Sire, Guy Theraulaz.** DATA:Experimental data of three-dimensional trajectories of a single fish (Hemigrammus rhodostomus) swimming freely in a hemispherical bowl in company of a virtual conspecific describing fixed circular trajectories with different speeds in a open-loop virtual reality system. A fully three-dimensional, data-driven model is used to produce fish trajectories in the same conditions.Data sets have the same structure of 9 columns containing the following information, in columns:#1: Experiment_ID#2: Index of time interval with continuous time.#3: Time (in seconds), with time step = 1/30 s.#4, #5, #6: x, y, and z coordinates of the real fish, in meters.#7, #8, #9: x, y, and z coordinates of the virtual fish, in meters.The origin of coordinates is located at the center of the water surface. The vertical coordinate z denotes the depth, which is zero at the surface and increases positively downward. The line (0,0,z) corresponds to the vertical axis of the sphere in which the bowl is inscribed.The files K1.dat to K6.dat correspond to the experimental conditions where the speed of the virtual fish is fixed at a constant value, v = 5, 7.5, 10, 11.67, 13.33, and 15 cm/s respectively.The files S1.dat to S6.dat are the numerical simulations corresponding to the respective experimental condition.In the experimental data, time is continuous in each interval, but not between intervals, so positions experiment a jump from one time interval to another. There are no jumps in the simulated data.** CODE:Model3D-VR.py: Python code to produce the numerical simulations of Conditions C1, C2, and C3 (among others).INPUT:- Parameters-Input.txt: External parameter file containing all interaction coefficientsFormat: space-separated values with parameter names and values (110 lines)OUTPUT:- PDF/Model_3D_PDF_*.dat: Probability distribution files containing:* Velocity distributions (v, dv, v_z)* Spatial distributions (r_w, r, z)* Angular distributions (theta_w, chi, psi, Dphi)* Distance distributions (d, d_z)- Trajectories/Model_3D_*_traj_*.dat: Trajectory files with:* Time series of x,y,z positions for all agents* Saved at specified time intervals
