Hi,
I'm having trouble with Roi.setProperty (or Roi.getProperty). The following
code requires an image to be open and requires one ROI to be added to the
ROI manager:

roiManager("select", 0);
Roi.setProperty("narrow",1);
print(Roi.getProperty("narrow"));

print("Property before re-select=" + Roi.getProperty("narrow"));

roiManager("select", 0);
print("Property after re-select=" + Roi.getProperty("narrow"));

When I run these lines of code, I get the following output:

1
Property before re-select=1
Property after re-select=

Why can't I select the ROI from the ROI manager again and get the property?

Thank you,
Avital
