FolderList.mat

Hi everyone,

I have a list of directories from which I would like to get the names of the files that they hold. An example list is attached. Then I would like to create an unified list with all the names of those files (from all the folders). I will need this list of files to feed it to another function. I hope this makes sense. I know that maybe using the function dir can help me with this, but I haven't found a way to implement it so it can read every cell from the folder list and get me the contents of it. I would appreciate your help.

Many thanks, Ramiro

See attached demos, for before and after release R2016b.

If you want, you could strip off the folder and call unique() on the base file names.

Thanks a lot for this. In the end I did a simpler solution with the code I already had.

%%Get Subject ID 
subid = inputdlg('Type Subject ID');
subid = str2double(subid{1});
%%Get the subfolder path
orig = ['/home/dantes/Documentos/Gambling_fmri/Originals/s' num2str(subid)];
sub = dir(orig); %get the subfolder names
subname = {sub(3).name};
subPathN = fullfile(orig,subname); 
subPath = subPathN{1};
%%Fetch all IMA files in those folders.
filePattern = sprintf('%s/**/*.IMA', subPath);
allFiles = dir(filePattern);
