I'm trying to read .vhdr files into MatLab in a loop function, but they all contain a different date in the filename. How can I get this to work? It's in the structure below where it starts with '01_' then has the subject number '####', then 'rest' and then the date of collection '02202021' then the .vhdr filetype.
File name structure: '01_####_rest_02202021.vhdr'
I have defined my subject numbers above in a variable called subject.
Such as:
subject = {'00001', '00002', '00003'}
EEG=poploadbv('C:/Users/M/Datasets',['01_',subject,'_Rest_','*.vhdr']);

Do you want to load all files inside a folder?
Folder = 'C:/Users/M/Datasets';
FileList = dir(fullfile(Folder, '*.vhdr'));
Data = cell(1, numel(FileList));
Subject = cell(1, numel(FileList));
for iFile = 1:numel(FileList)
FileName = FileList(iFile).name;
File = fullfile(FileList(iFile).folder, FileName);
Data{iFile} = poploadbv(File);
tmp = splitstr(FileName, '_';)
Subject{iFile} = tmp{2};
end

The files needed are actually contained within subdirectories by the subject number. So, inside Datasets is a folder for 00001 within that folder is the .vdhr that I need. Each file structure is the same, I just need the .vhdr file for each subject. The rest of the code should run per participant and then loop back around to restart for 00002.

@Meredith Abrams: Can you use the code I've suggested to your needs?

Hi there! Thank you so much! This code does not fit my needs as all of the data are stored in separate directories rather than a single directory. I may change the way they are stored and try this though.

Or use:
FileList = dir(fullfile(Folder, '**', '*.vhdr'));

I believe using two stars :
Folder = 'C:/Users/M/Datasets';
FileList = dir(fullfile(Folder, '**/*.vhdr'));
should work. Does it not?
