Analysis 1: Power spectral density (PSD) analysis across trials of a Reach2Grasp recording session. The PSD was computed and plotted (0–100 Hz range) for each trial available in the i140703-001 session and saved in a PNG file named after the trial ID number. The three versions of the analysis script (i.e., Analysis 1.1, 1.2, and 1.3) store the results in a specific root folder, identified by different colors in the figure. The versions use distinct methods and toolboxes to estimate the PSD: Elephant toolbox with the Welch method (blue), Elephant toolbox with the multitaper method (green), or SciPy using the Welch method (red). Overall, all 160 files are stored in each main output folder for this analysis (trial 142 is ignored). Plots of the same trial across the versions (shown here: trial 35) show that the outputs from the two analyses using the Welch method are visually indistinguishable, contrasting with the multitaper method.
