MATLAB: Folder in a directory

A = dir % you get everything in current directly of matlab.  or if you want to explicitly mention any directory path then you can do it like this.
A = dir('/yourpath');

now A has all files and directories. So you can access by loop

A(1).name

to get only Directory indexes you can do following code.

myDir = find(vertcat(A.isdir));

now myDir has indexes of directory(folders only).

to print the name of directory to confirm, you can do it like this.

A(myDir).name

where first two are only the pointers. you can always start your loop from 3. Ignore first two indexes.

MATLAB: There are two main folders which have 50 sub-folder each. In sub-folders there are tiff images. How to read images from sub-folders.

% Create a cell array of pre-defined directory locations
  folders = {'/media/DATA/M-001';'/media/DATA/M-002'};
  for i = 1:numel(folders) % Loop through all folders in pre-defined cell array
      myFolder = folders{i}; % Set folder to be processed

      % Extract all sub-folders from the current folder
      d = dir(myFolder); % List folder contents
      idxs = [d(:).isdir]'; % Logical vector of directory contents that are folders
      names = {d(:).name}'; % List of the names of all contents of the directory
      folders = names(idxs); % Index into 'names' using 'idxs'
      folders(ismember(folders,{'.','..'})) = []; % Remove '.' and '..' if they exist
      for i = 1:numel(folders) % Loop through all sub-folders in cell array
          myFolder = folders{i}; % Set folder to be processed
          % Add file processing commands here
      end
  end
