Played around a bit, ended up with set(handles.currimage, 'ButtonDownFcn',{@axes1_ButtonDownFcn,handles}); and now it works! I click, it gives coordinates. Now my issue is figuring out what the coordinates mean.. haha... Coordinates from the axes object were much more straightforward. Now I'm getting huge negative numbers.

Now my issue is figuring out what the coordinates mean.. haha... > Coordinates from the axes object were much more straightforward. Now I'm getting huge negative numbers. So it seems my problem is not solved. This method for setting the ButtonDownFcn for the image object doesn't seem to pass the handles correctly to the callback. I can't reference any of my program variables properly from within the callback. Is my syntax correct? set(handles.currimage, 'ButtonDownFcn',{@axes1_ButtonDownFcn,handles}); I tried changing it to set(handles.currimage, 'ButtonDownFcn',{@axes1_ButtonDownFcn,hObject, eventdata, handles}); but then I get the following error: ??? Error using ==> min_analysis>axes1_ButtonDownFcn Too many input arguments. ??? Error while evaluating image ButtonDownFcn I'm confused about this "@" notation and how exactly this function is being passed.
