Using push button to run function based on checkboxes

I have a GUI that has a few check boxes (cell diameter, cell size, and centroid) and when I click a push button, I want it to calculate the values of just the boxes that were checked. I have the coding for each of these check boxes in their call back, but when I run the GUI and 'check' the boxes, it runs those functions immediately. How can I get them to appear just when the boxes are checked and after I have clicked the push buttom?

Don't write anything in the callbacks of the checkboxes. In the callback for your button write the code to execute the functions associated with each checkbox. See the example below:

% --- Execute on button press in PushButton
  function PushButton_Callback(hObject, eventdata, handles)
  % hObjet  handle to PushButton 
  % eventdata  reserved - to be defined in a future version of MATLAB
  % handles   structure with handles and user data (see GUIDATA)

    cellDiameter = get(handles.cellDiametercheckbox,'Value');
    cellSize = get(handles.cellSizecheckbox,'Value');
    centroid = get(handles.centroidcheckbox, 'Value');

    if cellDiameter
      % write your function here for cell diameter
     end

     if cellSize
      % write you function here for cell size
     end

    if centroid
     % write your function here for centroid
    end

   % --- Execute on button press in cellDiametercheckbox.
   function cellDiametercheckbox_Callback(hObject, eventdata, handles)
   % hObject  handle to cellDiametercheckbox (see GCBO)
   % eventdata reserved - to be defined in a future version of MATLAB
   % handles structure with handles and user data (see GUIDATA)

% --- Execute on button press in cellSizecheckbox.
 function cellSizecheckbox_Callback(hObject, eventdata, handles)
 % hObject  handle to cellSizecheckbox (see GCBO)
 % eventdata reserved - to be defined in a future version of MATLAB
 % handles structure with handles and user data (see GUIDATA)

% --- Execute on button press in cellSizecheckbox.
 function centroidcheckbox_Callback(hObject, eventdata, handles)
 % hObject  handle to centroidcheckbox (see GCBO)
 % eventdata reserved - to be defined in a future version of MATLAB
 % handles structure with handles and user data (see GUIDATA)

Move the code to the callback for your button and include an if-statement around that code that queries the state (the Value property) of your checkbox.
