Help needed to write a macro to merge several polygon regions into one

[Dilip Baluguri]

Hi,
   I need a macro to merge several polygon regions into one region.
Initially I have one selected region and after every iteration of for loop
I get a new region. By the end of this for loop I should have only one
polygon which combines all those polygons

Dilip,
As you're creating new ROIs, add them to the ROI Manager.
At the end of the loop, use the Combine command. Also check the other
roiManager() functions at:

This example creates 2 ROIs and combines them.

run("Blobs (25K)");
makeRectangle(7, 21, 56, 49);
roiManager("Add");
makeRectangle(113, 47, 56, 49);
roiManager("Add");
roiManager("Combine");
