Why can't I open this .TRA file?

Hello everyone,

I do not know why I cannot open this file in MatLab. Can anyone help me?

fileID = fopen('Test_Zugversuche_PDMS_Probe 10.8_charge3.TRA');
file_data = textscan(fileID,'%f64 %f64 %f64 %f64','Delimiter','; ','HeaderLines',8);

Error using textscan
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in Young_Mod (line 56)
  file_data = textscan(fileID,'%f64 %f64 %f64 %f64','Delimiter','; ','HeaderLines',8);

filename = 'Test_Zugversuche_PDMS_Probe 10.8_charge3.TRA';
[fileID, message] = fopen(filename, 'r');
if fileID < 0
  error('Failed to open file "%s" because "%s"', filename, message);
end

My guess would be that the file is not in your current directory or anywhere along the MATLAB path.

Thanks! That was the problem.
