Thanks for your reply I ended up making the following code, but it does not bring me all the data.Can someone help me?

if true
  % 
[filename pathname]= uigetfile({'*.txt'},'Select .txt file');
              fullpathname = strcat(pathname, filename);
              app.locationFile.Value = fullpathname;
              textLocalization = fopen(fullpathname,'r');
              mesurements = textscan(textLocalization,'%d %d %d %f %d','HeaderLines',3,'Delimiter',' ');
              fclose(textLocalization);
              disp(mesurements)
end
