-Variables named "subject(1-6)" contain measurement results for different subjects. Inside each of the subject's results are cells representing different depths with respect to COST (with value given from -8px to 8px with 2px step). Each of these cells contains structs with measurement descriptions and results (in a similar way to Figure 2 and Figure 3).

-Variable named "frequency_characteristics" contains six rows representing each subject. Two columns contain frequency values (Hz) and average amplitudes of ORG signal (nm) for each subject respectively. There are nine cells for each subject as the signal was calculated at 9 depths (-8px to 8px with 2px step).

o    TimeFromStimulusIn_s: matrix of time vectors (each containing 290 datapoints) for each of the 48 datasets (48x290 double), representing the time from the stimulus in seconds, i.e., the x axis for each of the DeltaROS_vs_time figures.
