Hello, In my work I'm giving input as a folder of facial photos which consists of 10 images. The output enhanced images are getting stored in separate folder But the problem is, it is not getting stored in the same order as that of the images passed through input folder. The images are read randomly.

% Save all images name in a sequence manner before doing the operation
% names for example im1,im2,im3...
%Save the folder of images in the current directory
path_directory='folder_name'; % 'Folder name'
original_files=dir([path_directory '/*.jpg']);
for k=1:length(original_files)
filename=[path_directory '/' original_files(k).name];
image_orginal=imread(filename);
% Image read is done
%%Image Operation as per your work
end

Where would fullfile be used in the script then? Sorry I am new to coding and adapting this to create a for loop that changes file types (.oib to .tiff) and saves the new files in a different folder.

Presumably the filenames have numbers in them, and you are getting them listed not in numeric order...One solution is to download my FEX submission natsortfiles, which was written to solve that exact problem:
There are plenty of examples in the Mfile, in the online description, and in the HTML documentation, so you should not have any problems using it. You will probably want something like this:
D = 'path of the folder where the files are';
S = dir(fullfile(D,'*.txt'));
F = natsortfiles({S.name});
for k = 1:numel(F)
im = imread(fullfile(D,F{k}))
...
end

Hello,
I want to ask, how to use natsortfiles to sort alphanumerically overlaying plots in one figure? I find it difficult to match one plot to another because they have different directories and names.

@Manuella Juwita: What are "alphanumerically overlaying plots in one figure"? Plots do not have directories.
