I tried this but did not succeeded yet as i get some error messages, but
i will try again.
Actually I wanted to adapt this code taken from :

// ROI Manager Stack Demo
//

  n = roiManager("count");
  for (i=0; i<n; i++) {
      roiManager("select", i);
      getStatistics(area, mean);
      setResult("Area",  i, area);
      setResult("Mean", i, mean);
  }
  updateResults();
  roiManager("deselect");


and instead of making measurements I would rather go for a duplicate
image command I tried different ways but it does not work yet, one of my
macros get stuck to the first ROI and another version only displays the
last particle...
To me the advantage of using the ROI manager is to vizualize the
selected particles and to have the opportunity to discard not relevant
particles.
