Hi I'm trying to run this code right now but it shows "Not enough input arguments" and "Error in GetData (line 13): load([EnvDir 'Envelope_​F.mat'],'E​nvelope_F'​);"

function [stimSet, respSet, stimUnatt] = GetData(EnvDir, EEGDataDir)
% Loading proposed EEG data and speech envlope data
% Inputs:
%       EnvelopeDir - the extracted envlope directory
%       EEGDataDir - EEG dir for one subjesct
% Outputs:
%       stim - set of stimuli [cell{1,trials}(time by features)]
%       resp - set of neural responses [cell{1,trials}(time by channels)]
%       stimUnatt - set of unattended envlope [cell{1,trials}(time by
%       features)]

% load speech envelope data
load([EnvDir 'Envelope_F.mat'],'Envelope_F');
load([EnvDir 'Envelope_M.mat'],'Envelope_M');

Hi,

Your function 'GetData' expects two input arguments. You need to give exactly two inputs otherwise, it will give that error 'Not enough input arguments'.

If your error is in this line:

load([EnvDir 'Envelope_F.mat'],'Envelope_F');

There are two possibilities:

1. EnvDir has some incorrect value
2. The file 'Envelope_F.mat' is not in the MATLAB path

yes，sir，this is function，so please check the parameters，or set the default parameters， such as

function [stimSet, respSet, stimUnatt] = GetData(EnvDir, EEGDataDir)
% Loading proposed EEG data and speech envlope data
% Inputs:
%       EnvelopeDir - the extracted envlope directory
%       EEGDataDir - EEG dir for one subjesct
% Outputs:
%       stim - set of stimuli [cell{1,trials}(time by features)]
%       resp - set of neural responses [cell{1,trials}(time by channels)]
%       stimUnatt - set of unattended envlope [cell{1,trials}(time by
%       features)]
% load speech envelope data
if nargin < 1
    EnvDir = './';
end
load([EnvDir 'Envelope_F.mat'],'Envelope_F');
load([EnvDir 'Envelope_M.mat'],'Envelope_M');

You cannot run that function by pressing the green Run button; you must pass in at least one parameter, either by calling it in code or by going to the command line and typing in a call as a command.
