Hi,

I recently made a gui for manually scanning images and annotating them. It was running Ok (i.e from guide or openfig). I had done some initializations in the opening_fcn. But for some reason now when a try to open it, the initialization do not occur (i put in test strings in it) and the gui is giving me error because of undefined variables. I tried running on another machine, the same problem. If I run in debug mode then it goes through the opening_fcn and displays the string. I don't understand whats going on ??

please help

Paulo's guess about you having renamed something is reasonable. I would, however, first suspect something more simple.

You cannot run a .fig file by opening it or using openfig. You must run the gui program by name; it will open the .fig file.

thanksa lot. simply running by typing the filename works ! but I still wonder I was doing it the guide/openfig all along....

one more problem though. guide is erratic in putting callback functions automatically, for any new functionality I add to the gui. I even tried naming the callback and putting the entry in the .m file manually but it does not work. for example I have a button with tag 'jumpfile' guide did not insert the callback, so I inserted the jumpfile_Callback in the file. also added test string to the code (see below)

function jumpfile_Callback(hObject, eventdata, handles) % hObject handle to Untitled_1 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) 'teststring'

but when I press that button i get the error

??? Undefined function or variable 'jumpfile_callback'.

??? Error while evaluating uicontrol Callback

Sorry, I have no idea why the callbacks are not being added, unless you have renamed your gui.

With respect to having added your own routine: notice that you defined a routine with a capital-C in "Callback", but it is looking for a routine with a lower-case-c "callback"
