rename files using data in cell array
显示 更早的评论
hi, I have a list of 135 .mat files with complete file path. I have to take subjectid from the file path ( for eg. /project/brain/12345/matrix_456.mat) I want to copy these files into a new folder and rename them with brain_id_filename. So for this case it will be brain_12345_matrix_456.mat. I was able to copy these files into a new folder using copyfile but i am unable to rename them. thanks in advance.

You can rename files using copyfile() or movefile().
In either case the destination argument would be the new name of the file (not a folder), and it's best to use full absolute paths, e.g.:
copyfile('/home/project/brain/12345/matrix_456.mat','/home/project/brain_12345_matrix_456.mat');

If you want to rename the files, destination will have to be the new file name. It will be different each time through the loop.
You can set up a cell array containing the new file names, e.g.:
old_files = { ...
'/project/brain/12345/matrix_456.mat'; ...
'/project/brain/12345/matrix_789.mat'; ...
'/project/brain/99999/matrix_000.mat'}; % you say you have this already
new_files = strrep(old_files,filesep(),'_') % something like this, maybe not exactly
for ii = 1:numel(new_files)
copyfile(old_files{ii},new_files{ii});
end
