How can I color map the above folder dog since it contains 22 files in .dcm format.

It is showing the following error.

Error using fseek

Invalid file identifier. Use fopen to generate a valid file identifier.

Error in images.internal.dicom.getFileDetails (line 22)

fseek(fid, 0, 'eof');

Error in dicomread>newDicomread (line 197)

fileDetails = images.internal.dicom.getFileDetails(filename, verifyIsDICOM);

Error in dicomread (line 91)

[X, map, alpha, overlays] = newDicomread(msgname, frames, useVRHeuristic);

Error in partc (line 13)

details = dicomCollection(fullfile(matlabroot,'toolbox/images/imdata'));

clc; clear all; close all;
details = dicomCollection(fullfile(matlabroot,'toolbox/images/imdata'));
disp(details);
A=details("s3",14);
B=A(1,:).Filenames{1};
Y=[];cmap=[];
for i = 1 : length(B)
Y{i}=mat2gray(dicomread(B{i}));
end
montage(Y, 'Size', [5 5]);

[Cris LaPierre]

That appears to be correct. That is a series of images (22 images). You can find them here:

fullfile(matlabroot,'toolbox/images/imdata/dog')
