Hi,

i guess you need more or less this kind of code :

for i = 1:5000
    FileToRewrite = ['DatFile_' num2str(i) '.dat'];
      % phase 1 : read the ith dat file
      fid = fopen(FileToRewrite,'r');
      TextDat = textscan(fid,'%s','delimiter','\n');
      fclose(fid);
      % phase 2 : just take from the 4th line (3 headers) until the end-3
      % (3 footers)
      NewTextDat = TextDat{1}(3+1:end-3);
      % phase 3 : rewrite the file with the new data
      fid = fopen(FileToRewrite,'wt');
      fprintf(fid,'%s\n',NewTextDat{:});
      fclose(fid);
  end
