can u help me to solve this code error ?

function varargout = untitled(varargin)
% UNTITLED M-file for untitled.fig
%      UNTITLED, by itself, creates a new UNTITLED or raises the existing

%
%      H = UNTITLED returns the handle to a new UNTITLED or the handle to

WHAT CODE ERROR?

Do you intend for us to run your code, figure out what this undocumented code is supposed to do, figure out what does not work?

Provide the error message. If you want help, then make it possible for someone to help you. Add the COMPLETE error text.

Mohmd - you have two push button callbacks as follows

 function pushbutton1_Callback(hObject, eventdata, handles)
 humanHEXA = getgenbank('NM_000520')
 humanProtein = nt2aa(humanHEXA.Sequence,'frame',3)

 function pushbutton2_Callback(hObject, eventdata, handles)
 mouseHEXA = getgenbank('AK080777')
 mouseProtein = nt2aa(mouseHEXA.Sequence)

where each defines local variables humanProtein and mouseProtein respectively. Your checkbox callbox is defined as

 function checkbox2_Callback(hObject, eventdata, handles)
 seqdotplot(mouseProtein,humanProtein,4,3)
 ylabel('Mouse hexosaminidase A (alpha subunit)')
 xlabel('Human hexosaminidase A (alpha subunit)')

The first line of code (after the signature) references two undefined variables, the mouseProtein and humnaProtein. This is probably the source of your error: your code is referencing variables that have been defined locally in other callbacks. When using GUIDE to design your GUI, if you create a local variable in one callback function that you want to reference in another callback function, you need to save this variables as user-defined data within the handles structure. To do this, change your pushbutton callbacks as follows

 function pushbutton1_Callback(hObject, eventdata, handles)
 humanHEXA = getgenbank('NM_000520');
 handles.humanProtein = nt2aa(humanHEXA.Sequence,'frame',3);
 guidata(hObject,handles);

 function pushbutton2_Callback(hObject, eventdata, handles)
 mouseHEXA = getgenbank('AK080777');
 handles.mouseProtein = nt2aa(mouseHEXA.Sequence);
 guidata(hObject,handles);

In the above, we save each local variables as a field within handles and then save the updated structure using guidata. Now, in your checkbox callback, you would do

 function checkbox2_Callback(hObject, eventdata, handles)
 if isfield(handles,'mouseProtein') && isfield(handles,'humanProtein')
     seqdotplot(handles.mouseProtein,handles.humanProtein,4,3);
     ylabel('Mouse hexosaminidase A (alpha subunit)');
     xlabel('Human hexosaminidase A (alpha subunit)');
 end

In the above, we check to see if the handles structure has the two fields that we are interested in using isfield. If both exist, then we get each variable by accessing the desired field within that structure.

Try the above and see what happens!

[babita kapoor]

function pushbutton2_Callback(hObject, eventdata, handles) % hObject handle to pushbutton2 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) if handles.rad2==1

else [handles.sfilename handles.spathname]=uigetfile({'*.jpg';'*.png';'*.bmp';'*.*'},'Select an Image'); imageinfo_cover=imfinfo([handles.spathname handles.sfilename]); image_height=imageinfo_cover.Height; image_width=imageinfo_cover.Width;

    equ=image_width*image_height;

    if equ <=handles.equ
    I=imread([handles.spathname handles.sfilename]);
    set(handles.pushbutton3,'Enable','on');
    axes(handles.axes2);%#ok
    image(I);axis off
    else
    errordlg('Select another Image','Image too big');    
    end
    guidata(hObject, handles);
end

babita - please don't post a question as an answer to another question. Delete this answer and create a new question. When you do so, please make sure that your code is formatted correctly and that you describe what the error (or problem is) copying and pasting the full error message.
