Error in pop_ loadset

I failed to load a set file by EEGLAB. The error message is "EEGLAB error in function pop_loadset() at line 155".

The code at line 155 is TMPVAR = load('-mat', filename). The set file is downloaded from openneuro and the file type is alias.

I cannot load all files downloaded from openneuro. Please tell me what causes this error and how to load set files downloaded from openneuro.

Hi Oihtoyoshi,

I recognize that you are encountering issue in loading the ‘.set’ file by EEGLAB in MATLAB using ‘pop_loadset’ function.

The possible work arounds to resolve the issue are:

• Open the EEGLAB graphical user interface by typing ‘eeglab’ in the MATLAB command window, select File->Load_existing_dataset then select the ‘.set’ file.
• You can add the path of EEGLAB with ‘Add and subfolders’. Consider below given code snippet to add path.

% Specify the path to the EEGLAB folder 
eeglabPath = 'C:\path\to\eeglab\'; 
% Add EEGLAB and all its subfolders to the MATLAB path 
addpath(genpath(eeglabPath)); 
% Save the path for future MATLAB sessions (optional) 
savepath; 
% Now load the ‘.set’ file using ‘pop_loadset’.

• Furthermore, absence of particular ‘.set’ file acts as a potential reason for the error. Verify whether the file exists; if it does not, proceed with loading the other files, which should resolve the issue.

For more information, you can refer to the following MATLAB answers which provides a method to proceed if a file is not present in the directory.
