Hi, I have written the code:
>> path = {'/Users/Naomi/Desktop/GroupAnalysis/sub1/STRUC'};
>> movefile('s0-0007-00001-000001-01.nii', 'T1.nii')
Error using movefile
mv: rename /Users/naomi/Desktop/GroupAnalysis/s0-0007-00001-000001-01.nii to
/Users/naomi/Desktop/GroupAnalysis/T1.nii: No such file or directory
And I am receiving the above error message. Why is my file not being selected in the STRUC subfolder even if I am indicating it in the path?

Do not overwrite path, the built-in variable or you will have problems.
Make sure the file exists. It's telling you your source file is not there.

Yes you can. But it's best not to use cd and to just use the full file name when you call movefile(). See the FAQ: https://matlab.wikia.com/wiki/FAQ#Where_did_my_file_go.3F_The_risks_of_using_the_cd_function.
Also, use exist(sourceFileName, 'file') before you call movefile() to make sure it exists first.
And, AGAIN DO NOT USE path AS THE NAME OF YOUR VARIABLE or you will regret it. I can't emphasize that enough.

Instead of using cd to modify the current folder, it is safer to use absolute paths:
for k = 1:10
Folder = sprintf('/Users/Naomi/Desktop/GroupAnalysis/sub%d/STRUC', k);
movefile(fullfile(Folder, 's0-0007-00001-000001-01.nii'), ...
fullfile(Folder, 'T1.nii'));
end

Thank you! The program created a folder T1.nii within the folder STRUC, is there a way to change the file name rather than create a folder name?
