Change localization of files

Hi! I grouped the filenames according to a certain characteristic and now I wanted to save each file in a folder of the respective group.

I tried this but the code is not saving the files on the groups G1,G2,... in the path

G = {G1 G2 G3 G4 G5 G6};
path="C:\Users\35191\OneDrive - Universidade de Aveiro\Emotional transition - recognition\S1.mat";

cd 
fileList = dir(fullfile(path));
AllFilenames = {fileList.name};

F_matrix = AllFilenames(:,3:end)';

F_matrix = convertCharsToStrings(F_matrix);
N=length(F_matrix);


% Group by name
% for i=1:6
% 
%         C_G{i} = find(ismember(F_matrix,G{i}));
%         Group{i}=F_matrix(C_G{i});
% end



for j=1:(N-2)
    cd(path)
    %Read data
    file=fileList(j+2).name;
    load(file)
    if 1i == 1
        C_G{1} = find(ismember(file,G{1}));
        load(file)
        cd 'C:\Users\35191\OneDrive - Universidade de Aveiro\Emotional transition - recognition\G1'
        save file
    elseif 1i ==2
        C_G{2} = find(ismember(file,G{2}));
        cd 'C:\Users\35191\OneDrive - Universidade de Aveiro\Emotional transition - recognition\G2'
        save file

    elseif 1i ==  3
        C_G{3} = find(ismember(file,G{3}));
        cd 'C:\Users\35191\OneDrive - Universidade de Aveiro\Emotional transition - recognition\G3'
        save file
    elseif 1i == 4
        C_G{4} = find(ismember(file,G{4}));
        cd 'C:\Users\35191\OneDrive - Universidade de Aveiro\Emotional transition - recognition\G4'
        save file
    elseif 1i == 5
        C_G{5} = find(ismember(file,G{5}));
        cd 'C:\Users\35191\OneDrive - Universidade de Aveiro\Emotional transition - recognition\G5'
        save file.mat
    elseif 1i == 6
        C_G{6} = find(ismember(file,G{6}));
        cd 'C:\Users\35191\OneDrive - Universidade de Aveiro\Emotional transition - recognition\G6'
        save file 
    end
end

Avoid to use the name "path" for a local variable. This is an important Matlab command and redefining it can have very strange side effects during debugging.

fullfile(path) concatenates the contents of the variable path with nothing. fullfile is not meaningful with a single input only.

F_matrix = AllFilenames(:,3:end)'

It is not documented, that . and .. are the first two elements replied by dir. Safer:

F_matrix = setdiff(AllFilenames, {'.', '..'});

But you do not use F_matrix later, so simply omit this code.

load(file)
cd 'C:\Users\35191\OneDrive - Universidade de Aveiro\Emotional transition - recognition\G1'
save file

This loads the file whose name is stored in the variable named file, changes directory, then saves a file named file (not a file whose name is stored in the variable named file.)

save(X) % Save to the file whose name is stored in the variable x

save X % Save to the file whose name is X, equivalent to
save('X') % Save to the file whose name is X

if 1i == 1

This not true in any case. 1i is the imaginary unit. sqrt(-1) is not equal to 1 in any case. It is not 2,3,4,5,6 also. So non of the if branches will be entered.

Do you mean "j" instead of "1i"?

What is the purpose of the code? "save file" stores all variables of the current workspace in a file called "file.mat". Is this useful?

What is the contents of G1, G2, ...?

I assume, that the code can be simplified. Maybe:

BaseFolder = ['C:\Users\35191\OneDrive - Universidade de Aveiro\', ...
    'Emotional transition - recognition'];
data     = load(fullfile(BaseFolder, 'S1.mat');
fileList = dir(fullfile(BaseFolder, '*.mat'));
fileList = setdiff(fileList, {'.', '..'});

for k = 1:6
   ... % Something which uses the cell G?!
   file = fileList(k);
   save(fullfile(BaseFolder, sprintf('G%d', k), file), '-struct', 'data');
end

Hi! i i have one folder with many files '.mat'

The data inside respect 6 different sequences. I want to group the files that have the same sequence in one folder. I tried to change to your suggestion but this shows:

Error using load
Unable to read file 'C:\Users\35191\OneDrive - Universidade
de Aveiro\Emotional transition - recognition\S1.mat'. Input
cannot be a directory.

Error in FilesByEmotionSequency (line 39)
data     = load(fullfile(BaseFolder, 'S1.mat'));

[Rita Barnabé]

they are 6 sequences

Is "S1.mat" a diretory?

What are "sequences"?
