Hi Jan:

Thanks a lot for your reply. It seems working, however the result is not
quite same as running with Fiji UI. Particularly, Runing Analyze Particles
with Fiji UI gives less number of cell counted than using macros, although
they both called
run("Analyze Particles...", "size=0-Infinity circularity=0.00-1.00
show=[Overlay Outlines] display record slice");
I am not sure what the problem is, perhaps some parameter settings that
matter. In Fiji UI mode, I simply clicked "Analyze Particles" -> "Overlay
Outlines -> "size=0-Infinity" -> "circularity=0.00-1.00". I guess I need to
play with it a little more.

The run("Flatten") works perfect!

Thank you so much for your time and advice. I really appreciate it.

Best,
Nick
