Selection_tool trouble

Girault France
Dear all,
 
 
I've a little problem with the creation of selection:
 
I've an object with holes (having the background color) in it, when I create a selection the holes are selected as well as individual objects. I would like to keep only the circle itself.
I've tried:
 
setThreshold(2, 255);
run("Convert to Mask");
run("Fill Holes");
run("Create Selection");
run("Revert");
run("8-bit");
run("Restore Selection");
 
 
The circle is not restored properly, but another selection I've done on a previews image....
If I just run the measurement on the selection (holes and circle), only one of the hole is measured and the rest is removed. I'm interested in measuring the object as a whole, so what is in the circle, not each small hole.
 
Is there another way to go around this problem, did I do something wrong?
 
Any suggestion?
 
Thanks in advance,
 
France

In ImageJ 1.39f, due by the end of this week, the "Revert" command no
longer deletes the selection, making the "Restore Selection"
unnecessary.
