Hello Everybody!

I have created a stand alone exe from simulink model. And now i want to control it by GUI. Everything is working fine, i.e the mat file myrtp.mat has all the required parameters and when i tried to run my model as described in ''help rsimgetrtp'' from command prompt it works fine. And when i tried to use the same methodology in the call back function of GUI pushbutton, i am not getting any error but progress bar shows BUSY for sometime and then nothing happens. here is the pushbutton call back code. Can any one tell me what's missing here:

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

if ~isdeployed
    depath=which('Data_Test.xls');
else
    depath=[ctfroot,'\Matlab Work\maabhen\Data_Test.xls'];
end

Inputs;
if ~isdeployed
        npa=which('myrtp.mat');
        cd (fileparts(npa))
        load myrtp.mat
    else
        load ([ctfroot,'\Matlab Work\maabhen\myrtp.mat'])
        
    
if ~isdeployed
        save myrtp.mat rtp;
        exeloc='ADM3.exe';
        runstr = ['!',exeloc,' ','-p',' ',['G:\Master Thesis\Matlab Work\maabhen\myrtp.mat'],' ',...
            '-f',' ','input.mat=input.mat',' ','-f',' ','flowrate.mat=flowrate.mat',...
            ' ','-tf',' ',24];
else
        %curd=pwd;
        cd([ctfroot,'G:\Master Thesis\Matlab Work\maabhen\rtw\'])
        save ('myrtp.mat', 'rtp');
        exeloc='ADM3.exe';
        runstr=['!',exeloc,' ','-p',' ','myrtp.mat',...
            ' ','-f',' ','input.mat=input.mat',' ','-f',' ','flowrate.mat=flowrate.mat',...
            ' ','-tf',' ',num2str(Sim_Time)];
        %cd(curd)
        s=[];
end
load ([ctfroot,'G:\Master Thesis\Matlab Work\maabhen\ADM3.mat'])
end

a hint:
- put a KEYBOARD statement at the beginning of your callback function...
- call it...
- the editor opens the file at the KEYBOARD statement...
- once you're in debug mode, see what happens if you walk through your
  function, eg, examine variables, the flow,etc,...

Ok i know where is the problem now:

if ~isdeployed
        npa=which('myrtp.mat');
        cd (fileparts(npa))
        load myrtp.mat;
    else
        load ([ctfroot,'\Matlab Work\maabhen\myrtp.mat'])
end
        
    ind=rtp.parameters.map(1).ValueIndices;
    ind2=rtp.parameters.map(2).ValueIndices;
    ind3=rtp.parameters.map(3).ValueIndices;
    
    
    rtp.parameters.values(1,ind(1):ind(2))=DIM_D;
    rtp.parameters.values(1,ind2(1):ind2(2))=DIGESTERPAR;
    rtp.parameters.values(1,ind3(1):ind3(2))=DIGESTERINIT;
     
    
if ~isdeployed
        save myrtp.mat rtp;

this is to read in new parameters and save it to old myrtp.mat. but now i am having the following error:

??? Error using ==> save
Variable 'rtp' not found.

Error in ==> MT>pushbuttonModel_Callback at 109
        save myrtp.mat rtp;

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

Error in ==> MT at 42
    gui_mainfcn(gui_State, varargin{:});

Error in ==>
guidemfile>@(hObject,eventdata)MT('pushbuttonModel_Callback',hObject,eventdata,guidata(hObject))


??? Error while evaluating uicontrol Callback

 Am i doing it the wrong way???  Any help would be appreciated.
