Ramon,

in the loop you may try:

open(dir1+listOD[i]);
img1 = getImageID();
open(dir2+listOC[i]);
img2 = getImageID();
imageCalculator("Subtract", img1, img2);
selectImage(img1);
save(getDirectory("imagej")+"/"+newDir+"/"+(i+1)+".tif");
close();
close();

... and perhaps you should use
    setBatchMode(false);
at the end of your macro.

... and as far as I know
    showProgress();
doesn't work this way. Read the manual!
