Hi Kees,

The code works just fine. I will work on it further.

Thanks for all the help.

Dear Rohitesh,

The below macro code is doing more or less what you want on the image you submitted. No idea if it will work on other images you have but give it a go

title = getTitle();
run("Duplicate...", " ");
run("8-bit");
run("Bandpass Filter...", "filter_large=40 filter_small=3 suppress=None tolerance=5 autoscale saturate"); run("Find Edges"); run("Find Edges"); run("Find Edges"); run("Auto Local Threshold", "method=Contrast radius=15 parameter_1=0 parameter_2=0 white"); run("Select All"); run("Enlarge...", "enlarge=-1"); run("Crop"); run("Analyze Particles...", "size=25000-Infinity add"); selectWindow(title); roiManager("Show All without labels");

Best wishes

Kees
