How to rename several several .mat in a file with rename

Hello,

I Have a question about the same subject.

I have several files: FoodS01HealthSession1.mat FoodS01PracticeSession1.mat FoodS01TasteSession1.mat FoodS01TestSession1.mat

That go from S01 to S021 and I would like to all rename them as following FoodSub110HealthSession1.mat FoodSub110PracticeSession1.mat FoodSub110TasteSession1.mat FoodSub110TestSession1.mat

from 110 to 130

I cannot manage doing it using the function rename, as I donnnot know how to correctly code the loop nor using the function.

Could anyone help me?

Thanks a lot

Hi Solene,

this should work

names = {'Health', 'Practice', 'Taste', 'Test'};
for iName = 1:numel(names)
  for iFile=1:21
    origName = sprintf('FoodS0%d%sSession1.mat', iFile, names{iName});
    newName  = sprintf('Food%d%sSession1.mat', iFile+109, names{iName});
    movefile(origName, newName);
  end
end

untested but should be more or less it. Edit: make the %d without leading zero and added the leading zero for all files.

Hope this helps,

Titus

Hello Titus,

Thanks for your answer. I looked and it exists but all my filenames are entitled 010, 011, 012...etc until 021.

Hello Titus,

Thanks a lot for your help. It works really well until subject O10: then MATLAB indicates

Error using movefile mv: rename /Users/admin/Desktop/PLACEBODIET/Resultats_task_eau_EEG_session_1_renamed/FoodS10HealthSession1.mat to /Users/admin/Desktop/PLACEBODIET/Resultats_task_eau_EEG_session_1_renamed/Food119HealthSession1.mat: No such file or directory

Error in Help_titus(line 11) movefile(origName, newName );

Do you have any idea why it bugs at this point?

best,

Solène

Dear Solène,

did you have a look, if the file /Users/admin/Desktop/PLACEBODIET/Resultats_task_eau_EEG_session_1_renamed/FoodS10HealthSession1.mat really exists?

I see it now: I thought it's 01, 02, ..., 09, 10, 11, but it is 01, 02, ..., 010, 011. I'll edit the answer.
