MATLAB: How to separate file name and put the number at the end to count files

count files

I want to write a script for counting files. For example, my file name is "transport 052412_#1 3D gfp_z000_ch00.tif". I want to do 2 things. Firstly, I want to separate this name into base_name,transport 052412, and,varied_name,#1 3D gfp_z000_ch00. Then, I want to put the number at the of the file name to count such as 001, 002, and so on.

From this objective, I used fileparts [pathstr,name,ext,versn] = fileparts('filename') to separate the name of the file but it didn't work. So could you give me some advice for this.

Thanks, Nopparat

Try this:

s = 'transport 052412_#1 3D gfp_z000_ch00.tif'
[folder baseFileName extension] = fileparts(s)
underlineLocations = find(baseFileName == '_')
part1 = baseFileName(1:underlineLocations(1)-1)
part2 = baseFileName(underlineLocations(1)+1:end)

but the sentence " Then, I want to put the number at the of the file name to count such as 001, 002, and so on." does not make sense. Do you want an output like 'transport 052412_#1 3D gfp_z000_ch00_001.tif'? You'd need to give one or two examples of an output filename so we know how to build it up from rearranging the various parts.

Maybe you mean this:

s = 'transport 052412_#1 3D gfp_z000_ch00.tif'
[folder baseFileName extension] = fileparts(s)
underlineLocations = find(baseFileName == '_')
part1 = baseFileName(1:underlineLocations(1)-1)
part2 = baseFileName(underlineLocations(1)+1:end-2)
for k = 1 : 5
  s = sprintf('%s_%s%2.2d.tif', part1, part2, k)
end

which gives this:

s =
transport 052412_#1 3D gfp_z000_ch00.tif
folder =
     ''
baseFileName =
transport 052412_#1 3D gfp_z000_ch00
extension =
.tif
underlineLocations =
    17    27    32
part1 =
transport 052412
part2 =
#1 3D gfp_z000_ch
s =
transport 052412_#1 3D gfp_z000_ch01.tif
s =
transport 052412_#1 3D gfp_z000_ch02.tif
s =
transport 052412_#1 3D gfp_z000_ch03.tif
s =
transport 052412_#1 3D gfp_z000_ch04.tif
s =
transport 052412_#1 3D gfp_z000_ch05.tif

MATLAB: I have few images, i want to create folders, and names of folders should be identical to images. and want to save those images in folders having identical names.

Try this:

% Specify the folder where the files live.
myFolder = 'D:\My Pictures\Misc'; % Wherever...
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.PNG'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
  baseFileName = theFiles(k).name;
  fullFileName = fullfile(myFolder, baseFileName);
  fprintf(1, 'Now reading %s\n', fullFileName);
  % Now do whatever you want with this file name,
  % such as reading it in as an image array with imread()
  imageArray = imread(fullFileName);
  imshow(imageArray);  % Display image.
  drawnow; % Force display to update immediately.
  % Create a folder with the base file name
  [~, baseFileNameNoExt, ~] = fileparts(baseFileName);
  outputFolder = fullfile(myFolder, baseFileNameNoExt);
  if ~exist(outputFolder, 'dir')
    mkdir(outputFolder);
    fprintf('Created folder : %s\n', outputFolder);
  end
  % Prepare output filename
  outputFileName = fullfile(outputFolder, baseFileName);
  % Copy file to that folder
  copyfile(fullFileName, outputFileName);
  fprintf('    Copied %s to the folder called %s.\n', baseFileName, outputFolder);
end
