You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: f_ERP_save_single_file.m
    path of file: ./repos/erplab/studio_functions/GUIs/ERP Tab
    
    the code of the file until where you have to start completion: function varargout = f_ERP_save_single_file(varargin)

function are returned to the command line.
function varargout = f_ERP_save_single_file_OutputFcn(hObject, eventdata, handles)

% Get default command line output from handles structure
% try
%     set(handles.menuerp.Children, 'Enable','on');
% catch
%     disp('ERPset menu was not found...')
% end
