For loop stops after Saving Images

I have a program that goes through a nested for loop after loading parameter's values. The only problem I have right now is that it only goes through the first iteration and after it saves it it just ends.

for TarScale = 0.001:0.100:1
   for JitterAmp = 0:0.33:0.66

$ it does some calculations
$ then it creates the filename which includes the values of the parameters so it should change everytime

if Nbits > 16
  fName = [nameString, '.raw']
  save(fName)
end
cd(oldfolder) $ which contains pathname

if Nbit > 16 
   writeSimData(oldfolder,fName, unint32(F5);
end

end 
end

The simData does this

    fid = fopen([dirName fileName], 'w');

 try 
    fwrite(fid,data','uint16');
 catch
 end

 fclose(fid);

 end

At this point I am just trying for the loop to continue until it goes through all the values.
