Dear professors,
        when I do the first step, I had some problems with filename error.After I set parameters ande click 'start',MATLAB was reporting that 'Error using fopen The file name contains characters that are not contained in the filesystem encoding.
Certain operations may not work as expected'. 
        I try to change all the filename but it did't work.I use matlab R2018A and  GTG_beta_045.Here are some pictures
with my work.
