Error while using a GUI

Hi MATLAB experts,

I've been getting these errors notifications when trying using a toolbox GUI (the m.file is attached):

>> MCMxxxVI_RGBExplorer
Undefined function or variable 'file'.

Error in MCMxxxVI_RGBExplorer>pushbutton1_Callback (line 116)
    [pathstr,name,ext]=fileparts(fullfile(pathname,file));

Error in gui_mainfcn (line 95)
        feval(varargin{:});

Error in MCMxxxVI_RGBExplorer (line 64)
    gui_mainfcn(gui_State, varargin{:});

Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)MCMxxxVI_RGBExplorer('pushbutton1_Callback',hObject,eventdata,guidata(hObject)) 
Error while evaluating UIControl Callback.

Would very appreciate any advice,

Tamir

MCMxxxVI_RGBExplorer.fig does not exist. Please share all necessary files to run the GUI and reproduce your error again.

There is no variable 'file' in your callback. However there is a variable 'file1'.

Hi Tamir,

Just change line 116 as follows, definetely it will work:

[pathstr,name,ext]=fileparts(fullfile(pathname,file1));
