to get the files from a folder try this:
selDossier = uigetdir; % ask for the folder
searchedExtension = '.hdr' ;
cd(selDossier); % go to the folder
currentFile = dir ; % read folder's content
selectedFile = {} ;
for i = 1:numel(currentFile) % look for files
if ~currentFile(i).isdir % discard subfolders
if strcmpi(currentFile(i).name(end-4:end),searchedExtension)
selectedFile{end+1} = currentFile(i).name ; %filename
end
end
end
of curse you can create a recursive function that returns all files while there's a subfolder in current folder!, that's some extra code you must write!
