HI i am doing a project on CT data(DICOM) image processing so i need to process(filtering) a bunch of dicom files in matlab for this how can i load and process a bucnh of DICOM files

this is my code i am getting error at I=dicomread(x{1});

CT = fullfile(CT data,'toolbox','images','imdata'); dirOutput = dir(fullfile(CT,'image000001*.dcm')); x = {dirOutput.name}; numFrames = numel(fileNames);

I = imread(x{1}); sequence = zeros([size(I) numFrames],class(I)); sequence(:,:,1) = I; % for p = 2:numFrames sequence(:,:,p) = imread(fileNames{p}); end

what error do you get precisely? The %3d is used to tell matlab the precision/format of numbers in your name for example.
