I don't understand what you're saying in the title of your question but the error message is very clear: you're trying to set the string property of your text6 control but that control does not exist anymore. Probably because you've closed the figure containing it.

% Get the string in the control called handles.edit_text1.
string1 = get(handles.edit_text1, 'String');
% Extract just a portion of it.
string2 = string1(1:3); % Or whatever you want to start and stop at.
% Send that string2 to the control called handles.edit_text2.
set(handles.edit_text2, 'String', string2);
drawnow; % If needed, like you're in an intensive loop.

MATLAB: Return data from GUIDE on figure close

To delay a GUIDE-GUI output until the GUI is closed, follow these steps. A functional demo is attached that produces an empty GUI and returns a hard-coded output when the GUI is closed. See comments in the m-file for help.

1) If your GUI does not already have a close request function, add one from within GUIDE by opening your GUI in GUIDE, right click the figure background, select View Callbacks, and the select CloseRequestFcn.

2) In the ..._OpeningFcn

function demoGui_OpeningFcn(hObject, eventdata, handles, varargin)
. . .
uiwait();  % add this to the end

3) In the ..._outputFcn

function varargout = demoGui_OutputFcn(hObject, eventdata, handles) 
varargout{1} = handles.output;
delete(hObject); % add this

4) In the ..._CloseRequestFcn you created from GUIDE,

function figure1_CloseRequestFcn(hObject, eventdata, handles) 
% delete(hObject);          % Remove this
handles.output = 3.1415926; % Produce or grab your outputs 
guidata(hObject, handles);  % Store the outputs in the GUI
uiresume()                  % resume UI which will trigger the OutputFcn
