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);
