Hi Jerome,

Thank you for the suggestion.  It works well for placing the 12x12 ROIs, but it doesn't allow me to click and drag to change size...

Hi Andrew,

I suggest something like this for now:

macro "increase size[1]"{
run("Enlarge...", "enlarge=5");
roiManager("Update");
}

macro "decrease size[2]"{
run("Enlarge...", "enlarge=-5");
roiManager("Update");
}

With these macros installed, you would press "1" to increase the radius of your currently selected ROI by 5, and "2" to decrease the radius of your currently selected ROI by 5. Try this with different numbers if you like.
