Experimental data and code from "<b>Closed-loop real–virtual interactions validate 3D </b><b>model of social coordination in fish</b>", with authors Ramón Escobedo, Justine Reynaud, Renaud Bastien, Stéphane Sanchez, Clément Sire, Guy Theraulaz.<b>** DATA:</b>Experimental data of three-dimensional trajectories of pairs of fish (<i>Hemigram</i><i>mus rhodostomus</i>) swimming freely in a hemispherical bowl, and of a single fish swimming in a closed-loop virtual reality system allowing it to interact in real time with a virtual conspecific whose movements are governed by a fully three-dimensional, data-driven model.Data sets have the same structure of <b>9 columns</b> containing the following information, in columns:#1: Experiment_ID<br>#2: Index of time interval with continuous time.<br>#3: Time (in seconds), with time step = 1/30 s.<br>#4, #5, #6: x, y, and z coordinates of individual 1, in meters.<br>#7, #8, #9: x, y, and z coordinates of individual 2, in meters.<br>The origin of coordinates is located at the center of the water surface. The vertical coordinate z denotes the <b>depth</b>, 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.In file <b>2R</b><b>-TwoRealFish.dat</b>, both individuals are <b>real fish</b>.In the files corresponding to Conditions C1, C2, and C3, <b>Cx</b><b>-OneReal+OneVirtual.dat</b> (x = 1,2,3), individual 1 is the <b>real fish</b> and individual 2 is the <b>virtual one</b>.Time is continuous in each interval, but not between intervals, so positions experiment a jump from one time interval to another.<b>** CODE:</b><b>Model3D-VR.py:</b> Python code to produce the numerical simulations of Conditions C1, C2, and C3 (among others).INPUT:<br>- <b>Parameters-Input.txt:</b> External parameter file containing all interaction coefficients<br>Format: space-separated values with parameter names and values (110 lines)<br><br>OUTPUT:<br>- <b>PDF/Model_3D_PDF_*.dat:</b> Probability distribution files containing:<br>* Velocity distributions (v, dv, v_z)<br>* Spatial distributions (r_w, r, z)<br>* Angular distributions (theta_w, chi, psi, Dphi)<br>* Distance distributions (d, d_z)<br><br>- <b>Trajectories/Model_3D_*_traj_*.dat:</b> Trajectory files with:<br>* Time series of x,y,z positions for all agents<br>* Saved at specified time intervals<br>
