Error with pop_loadcnt uploadingg ANT CNT files. EEGLAB

I am currently writing a script that imports a large number of ANT CNT files from a hard drive. However, I am having trouble with the load data function. I have tried using pop_loadcnt(). My code and the error message is shown below.

mainPath ='/Volumes/CARTBINDEEG/CART-BIND_UHN/'; % Main Folder of the data , It is better to use the full path with the drive name
subjects_ID={'001_01','001_02','001_03','003_01','003_02','004_01'}; % ID of the subjects

for i = 1:length(subjects_ID) % A loop for calling all data files from folders
    
    % Set path and select folders
    filePath = mainPath; % Set path of the file where the data file exists
    fileName = char(append('CBN02_TWH_',subjects_ID(i),'.cnt')); % Set the data name
    file = char(append(filePath,fileName));
    
    % Step 1: Load data
    % ask forum 
    EEG = pop_loadcnt(file, 'dataformat', 'auto', 'memmapfile', ''); % load file and Select Electrodes %MARKED
    EEG = eeg_checkset( EEG );
    
    % Step 2 : Set EEG name
    EEG.setname = fileName;
    EEG = eeg_checkset( EEG );
    
    %  Step 3  channel locations 
    EEG = pop_chanedit(EEG, 'lookup','/Users/garylin/Desktop/eeglab2021.1/plugins/dipfit/standard_BEM/elec/standard_1005.elc'); % EEGLAB standard channel locations
    EEG = eeg_checkset( EEG );
    
    % Step 4: Downsample the data to 250.
    EEG = pop_resample(EEG, 250);
    
    %   Save data 
    savePathfolder='/Users/garylin/Desktop/EEG Datasets/UHN Downsampled';  % Folder for saving the data
    EEG = pop_saveset(EEG, append(fileName,'_250') , savePathfolder); 
end

The file header says that each signal is 28257 long, and that there are 200443239 channels. That would require a file of over 5 petabytes, but instead the file is about 1100 times smaller than that.

The simplest explanation would be if the file is not in a format that is readable by pop_loadcnt

Have you installed the ANT eeglab plugin ? http://download.ant-neuro.com/matlab/

Hi, yes I have installed the ANT eeglab plugin. If ANT CNT files are not readable by pop_loadcnt, what function can read ANT CNT files? I can’t seem to find one that works. Thank you!

Sorry, I have never worked with those files.
