Set scale problem

[Vladimir Hegyi]

My apologies, problem is solved.
The new macro is as follow:

run("Set Scale...", "distance=99 known=0.05 pixel=1 unit=mm");
run("8-bit");
run("Rename...", "title=Cievy.bmp");
run("Duplicate...", "title=Cievy.bmp-copy");
run("Gaussian Blur...", "sigma=2");
run("Multiply...", "value=2.550");
run("Add...", "value=125");
run("Maximum Entropy Threshold");
run("Set Measurements...", "area perimeter feret's redirect=None decimal=3");
run("Analyze Particles...", "size=0-Infinity circularity=0.00-1.00
show=Outlines display exclude");

Now it works.
Thanks.
Vladimir
