Hello,

I am having difficulty understanding the "Combine" operation for the
RoiManager.  Here is an example...

(1) run the "RoiManagerAddParticles.txt" example macro availbale at

http://rsb.info.nih.gov/ij/macros/RoiManagerAddParticles.txt


(2) select the first and second ROIs by shift-clicking on...

        0005-0063
        0014-0108

(3) press the "Combine" button (both ROIs are highlighted)

(4) then press the "Measure" button

At this point two measurements are added - identical to the originals.
I expected a single measurement.  Is there a way to have ImageJ treat
the two as a single ROI?

Thanks and cheers,
Ben
