I have files in one folder named '123445_MD.nii.gz','123454_MD.nii.gz', and so on. (all the # of digits are same; all 7 digits; xxxxxxx_MD.nii.gz)
I want to change the file name with '123445_FA.nii.gz' ... so on. Meaning want to change MD to FA only.
Thank you in advance.

Something like this should work:
folder = 'C:\somewhere\somefolder'; %whichever folder contains the files
filelist = dir(fullfile(folder, '*.gz'));
for fileidx = 1:numel(filelist)
movefile(fullfile(folder, filelist(idx).name), fullfile(folder, strrep(filelist(idx).name), '_MD', '_FA'));
end

FOR LINUX:
find the list of files and replace the words that u want.
Example:
find . -name '*gz' -exec bash -c ' mv $0 ${0/\MD/FA}' {} \;
if it doesnt work; please have a look out there->

While indeed it may be a task more suited for the OS than matlab, note that this solution is linux only.
