I have two folders with names M-001 and M-002 and in each of the main folder, I have sub-folders which contain tiff images. How could I read both the main folders at the same time to read all the tiff images.

Thanks.

Thank you. I am trying something like this:

clc

mainDirectory = {'C:\Users\amazon\Desktop\Acq_001','C:\Users\amazon\Desktop\Acq_002'};

subDirectory = dir([mainDirectory '/L*']);

for m = 1:length(subDirectory)

subFolder = dir([mainDirectory '\' subDirectory(m).name '\*.tif']);

for i = 1:length(subFolder)

filename = strcat([mainDirectory '\' subDirectory(m).name '\' subFolder(i).name]);

I=imread(filename); %% Read Image

end

but I am getting an error Function is not defined for 'cell' inputs.

在 MATLAB Online 中打开

% 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
