Hi. I have a sequence of images (without extension) named S000009, S0000010, S0000011,.... There is no extension. They are just files but basically they are dicom images without the .dcm extension. I want to gather them altogether and dicomwrite them. Add the .dcm extension to them. Any idea?
Thank you

files = dir(); % you are in the folder where files are present
N = length(files) ;
for i = 3:N
oldfile = files(i).name ;
newfile = strcat(oldfile,'.dcm') ;
movefile(oldfile,newfile,'f');
end

Dear KSSV Your code is perfect. But I need a close that determines if the files have already a .dcm extension and not add them the dcm extension again and again whenever I run the script. For instance, I run the script twice and I got S0009.dcm.dcm. I probably get S0009.dcm.dcm.dcm if I run it for third time. Any idea? Thanks in advance
