After loading the MAT file (as in MATLAB with the load function), there are three variables (matrices): amplitude_complex_T1, amplitude_complex_T2, and amplitude_complex_info.

The headers of the data are stored in the amplitude_complex_info variable. Each row (with a length of 48) represents the data header of a pulse echo, with each position in the row representing a specific meaning as shown in the table. Each row of the amplitude_complex_info variable corresponds to each row in the amplitude_complex_T1 and amplitude_complex_T2 variables.
