I have a drop down list in my GUI. it consists of 5 axes, from which one main axes displays my selected image. I want to select the image from the drop list and it should be displayed in the first axes for further processing. At first when I was working on my GUI, this worked. But don't know how come this error appeared just when I run my GUI now.
the error is just on this very first statement of the callback:
axes(handles.axes1);
Error:
Struct contents reference from a non-struct array object.
I can't figure out my mistake. Help needed.

Ria3242 - typically, this type of error is due to the GUI not being launched correctly. If you launch the GUI using the fig file, then the variables (such as handles) will not be initialized correctly and you will see this error.
GUIDE-created GUIs can only be launched through the GUIDE editor (press the RUN button), the MATLAB file editor (again, press the RUN button), or by calling the GUI name from the command line. For example, if you have the MyGUI.m and MyGUI.fig files, you would do
>> MyGUI
to launch the GUI.
