[Eeglablist] Loading both .set and .fdt files in command line

[Velu Prabhakar Kumaravel]

Hi Patrick,

If you have EEGLAB 2021.0 installed, the following code should work (I
fixed a couple of errors). I think the .fdt files should be in the same
folder as .set files. Besides that, no special treatment is required.

filePath = '\eeglab2021.0\sample_data'; % your EEGLAB sample_data folder
path

filePattern = fullfile(filePath, '*.set' );
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
fprintf('File ID: %d\n', k)
baseFileName = theFiles(k).name;
fullFileName = fullfile(theFiles(k).folder, baseFileName);
fprintf(1, 'Now reading %s\n', fullFileName);
%EEG = pop_loadset(fullFileName); %STEP 1
EEG = pop_loadset('filename',baseFileName,'filepath',filePath);
disp(size(EEG.data))
end

Let me know if it works!
