Hello!

I'm following a video on creating a GUI with GUIDE ( http://www.mathworks.co.uk/videos/matlab/creating-a-gui-with-guide.html).

At 07:50 in the video, the speaker explains about generating or loading the data to be plotted. I'm trying to place a function call to my actual program here but this gives me an error I don't seem to understand.

The error is:

??? Error using ==> guidata at 89
H must be the handle to a figure or figure descendent.
Error in ==>
GUI_calciumDynamics_1>GUI_calciumDynamics_1_OpeningFcn at 80
guidata(hObject, handles);
Error in ==> gui_mainfcn at 221
    feval(gui_State.gui_OpeningFcn, gui_hFigure, [],
    guidata(gui_hFigure), varargin{:});
Error in ==> GUI_calciumDynamics_1 at 42
    gui_mainfcn(gui_State, varargin{:});

Could someone kindly advice me please?

Warm Regards

Amar

Workaround: This error can be avoided by loading the required variables rather than calling the actual function. I saved the variables needed for post-processing in a workspace and then loaded that workspace in the code for the GUI.

Any ideas to be able to use a function call directly in the GUI code are still welcome.
