I've been having strange problems with imellipse. I'm trying to run it in a loop to draw multiple ROIs but it either breaks out of the loop (with no error message), or gives me the following error, which makes little sense to me.
Operation terminated by user during uiwait (line 82)
In imroi>manageROIWaitMode (line 391)
uiwait(h_fig);
In imroi/wait (line 226)
accepted_pos = manageROIWaitMode(obj);
In imellipse/wait (line 118)
pos = wait@imroi(obj);
I distilled my code down to a very simple program, which still has this error (or does not complete the loops):
clc; close all
figure, imshow('pout.tif');
reps = 10;
positions = cell(1,reps);
for i = 1:reps
disp(i)
h = imellipse;
positions{i} = wait(h);
pause(0.5)
end
Appreciate your help.

Hi Anand, Thanks for your prompt response. I don't know what you mean by "clarify your workflow." On all of my computers, I start up MATLAB, run this code, and try draw ellipses as you did (and double-clicking on them). However, for me, it always just breaks out of the loop or causes an error after the first ellipse.
Do you have any ideas as to what may cause this?

Gerald, did you double-click inside the ellipse, or right click and say "Create mask"? What exactly did you do to "finish off" the ellipse and move on to the next one?

I think I found the culprit -- I recently installed a third-party application (which looks for mouse behavior in the background) that may have been responsible.
