+function [data, all_strings] = get_all_data_from_level_h5_rec(filename, str, data, all_strings)
+% This function recursively reads data from an HDF5 file.
+%
+% INPUT:
+%   filename: A string that identifies the HDF5 file from which to extract data.
+%   str: The group from which to start extracting data.
+%   data: A cell array to add and store the extracted data.
+%   all_strings: A cell array to add and store the paths of the extracted
+%   datasets (for control)
+%
+% OUTPUT:
+%   data: A cell array containing the extracted data for each dataset.
+%   all_strings: A cell array containing the paths of the extracted datasets.
