hi plz help me in this probleme i wont to créate a montage of dicom image with 26 images

s = dicomread('SE000005\IM00000.dcm'); [r c] = size(s);
X = repmat(int16(0), [256 256 0 25])
for i=1:26
    filename = sprintf('SE000005\\IM0000%d.dcm', i);
    X(:,:,1,i) = dicomread(filename);
end
montage(X,'displayrange',[]);

but

error in  X(:,:,1,i) = dicomread(filename);(Subscripted assignment dimension mismatch.)
)

Do you have the right dimensions? Looks like it must be a 4-D array. From the help:

montage(I) displays all the frames of a multiframe image array I in a single image object. I can be a sequence of binary, grayscale, or truecolor images. A binary or grayscale image sequence must be an M-by-N-by-1-by-K array. A truecolor image sequence must be an M-by-N-by-3-by-K array.

What does this say:

whos X

 X Empty array: 256-by-256-by-0-by-25

Well, there you go -- X is empty. You need to step through with the debugger to figure out why you're not reading in the files. Like, try using exist(). And try using the folder, even if it's pwd, and fullfile, like I did below:

filename = fullfile(pwd, sprintf('SE000005\\IM0000%d.dcm', i))
if ~exist(filename, 'file')
      message = sprintf('Error: file does not exist:\n%s', filename);
      uiwait(warndlg(message));
      continue;
end

yes thanks it works i change X = repmat(int16(0), [256 256 r c]
