Using Enlarge function with very large ROI sets

Dear experts,

I'm trying to quantify timelapse images with nuclear fluorescent marker for
segmentation and also take cytoplasmic measurements by enlarging ROIs.
However, because of very large ROI sets (>50,000), my macro ran very slow.

counts=roiManager("count");
for(i=0; i<counts; i++) {
    roiManager(&quot;Select&quot;, i);
    run(&quot;Measure&quot;);
    run(&quot;Enlarge...&quot;, &quot;enlarge=4&quot;);
    run(&quot;Measure&quot;);
}</b>

I've already setBatchMode("true").  It helps a little (save about half
time),  but I was wondering if there is a way to speed up my macro.

Thanks,
Jerry
