GUI commands transition from R2007 to R2018

Hello, I need to update data aquisition software from R2007 to R2018 and add PID controller. Script seems to work after transition from legacy based inerface to session based, but I have multiple errors when push bottons in gui:

Error using neurosys_4v5>DCLED_BUTTON_Callback (line 1051)

When using session based operations, use outputSingleScan.

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in neurosys_4v5 (line 41)

gui_mainfcn(gui_State, varargin{:});

Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)neurosys_4v5('DCLED_BUTTON_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback.

Lines 1050 - 1053:

    else
         putsample(handles.out,[0 get(handles.DCLAMP_BUTTON, 'value')*str2double(get(handles.DCLAMP_VALUE, 'String'))...
             handles.DC_OFFSET+0 handles.DC_OFFSET+0]);
    end

Error using neurosys_4v5>loadstimulus (line 859)

When using session based operations, use outputSingleScan.

Error in neurosys_4v5>loadstimpushbutton_Callback (line 1072)

[handles] = loadstimulus(handles);

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in neurosys_4v5 (line 41)

gui_mainfcn(gui_State, varargin{:});

Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)neurosys_4v5('loadstimpushbutton_Callback',hObject,eventdata,guidata(hObject))

Lines 858-862:

         else
        putsample(handles.out,[0 get(handles.DCLAMP_BUTTON, 'value')*str2double(get(handles.DCLAMP_VALUE, 'String'))...
        handles.DC_OFFSET+handles.L_gain*get(handles.tpl_checkbox,'Value')*handles.DCLED_ON*handles.DCLED-handles.DC_OFFSET*(handles.DCLED_ON > 0)...
        handles.DC_OFFSET+handles.L2_gain*get(handles.tpl2_checkbox,'Value')*handles.DCLED_ON*handles.DCLED-handles.DC_OFFSET*(handles.DCLED_ON > 0)])
     end

lines 1071-1073:

     function loadstimpushbutton_Callback(hObject, eventdata, handles)
[handles] = loadstimulus(handles);
guidata(hObject, handles);

could you please tell where I can find any instructions how to update these commands & fix error messages for gui?

[R]

The issues are likely stemming from the switch from the older DAQ interface techniques (putsample) to the newer session-based interface in MATLAB, a change that occurred with versions released around 2016.

The commands have undergone some modifications, for instance, `outputSingleScan` is now used for executing a single sample DAQ session instead of `putsample(handles.out, [...])`. Thus, you should replace this with `outputSingleScan(handles.out, [...])`. For further details on the legacy functionalities, their new usage formats, and other relevant compatibility information, execute the command below in your MATLAB command window:

web(fullfile(docroot, 'daq/release-notes.html?searchHighlight=putsample')) 

Additionally, for assistance in moving from the legacy to the session-based interface, consult the guide which lists the legacy functionality, new use format and other compatibility considerations at:

web(fullfile(docroot, 'daq/transition-your-code-to-session-based-interface.html?searchHighlight=Transition%20Your%20Code%20to%20Session-Based%20Interface')) 

For documentation on `outputSingleScan`, refer to:

web(fullfile(docroot, 'daq/ref/outputsinglescan.html?searchHighlight=outputSingleScan&s_tid=doc_srchtitle')) 

Also, as an important note, starting from R2020a, it is advised to utilize the DataAcquisition interface.

Thank you, R! "putsample" error is fixed now. However, I still need help as all other errors are still there. For example, these two as I understood are related to new graphic system introduced in Matlab2014b:

Error in gui_mainfcn (line 220)
feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});

Error in neurosys_ERG (line 40)
gui_mainfcn(gui_State, varargin{:});

Any suggestion how to fix these two?
