How do i save a file into a folder in a different path?

I am coding a project that uses neural networks. my neural networks are saved into the same path as this piece of code. i want to save each segmented image in another file location, each with a different name.

%Open files

testfiledir = 'X:\eee_biophotonics1\Shared\SPOT dataset (Training data)\Testing Images\123 images on 123 network\OCT';

matfiles = dir(fullfile(testfiledir, '*.tif'));

nfiles = length(matfiles); %finds length of file

data = cell(nfiles);

for i = 1 : nfiles

fid = fopen( fullfile(testfiledir, matfiles(i).name) ); %retrieves specific file

load('net_123.mat'); % This loads the network back into MATLAB

result = semanticseg(fid,net_123); % This segments an image "I" using the network

filename='X:\eee_biophotonics1\Shared\SPOT dataset (Training data)\Testing Images\123 images on 123 network\nn segmented';

save(result,'%d',i,'-tif');

fclose(fid);

end

%Open files for running through NN
fileNames_retrieve = dir(['dir_1\*.tif']);
foldername = ['dir_1'];
%retrieve directory for segmented images to be placed into
fileNames_save = ['dir_2'];
matfiles = length(fileNames_retrieve); %finds number of files in directory

for M = 1 : matfiles
    file = fileNames_retrieve(M).name; %finds name of the pre-segmented image
    im = fullfile(foldername,file);
    image = imread(im); %selects specific image
    result %add some process here
    fullFileName = fullfile(fileNames_save, file); %creates full 
    %directory to save file
    save(fullFileName, "result") %saves specific file
end

Hi Rachel,

That should be fairly straightforward. You can create:

• a new directory each iteration of the 'for' loop, and save your file there, and/or
• a new file each iteration of the 'for' loop, and save it in a pre-defined directory.

Here is an example in which I generate a new variable 'a' every iteration, and save it in a new folder that I create in the current directory each time (using a different file name every time as well):

for idx = 1:10

a = rand(5);

mydirname = [cd,'\TMP',num2str(idx)];

myfilename = [mydirname,'\file',num2str(idx),'.mat'];

mkdir(mydirname)

save(myfilename,'a')

end

I hope this is helpful!
