Hi all,

I've been creating ROIs using specific coordinates in images, and strangely I see that when I click on the ROI object in the workspace (1x1 Circle) and click on its properties (ex. Radius) there's just a message saying "The variable w.Radius does not exist".

When I call the property in the workspace with a w.Radius command, I get the message:

Invalid or deleted object. Error in images.roi.Circle/get.Radius

What's going on? I get the same message for other properties of the ROI, including Center, which is totally weird, because I actually gave it the coordinates in which it was supposed to position the center of the circle, which it did accurately (looking at the image).

Thanks for sharing your tips and expertise!

Best,

Veena

One can only be guess without seeing the code you used to end up with that error. Can you provide the code you've used so far or something representative of the steps your code implements?
