How do I write images into folders specified in string array?

Hi,

I have a 3545 x 2 string array. I attached the first 10 rows as an example:

namesandlabels(1:10, :)

ans = 

  10×2 string array

    "Image100.241.jpg"    "Membrane-Stained Cells"
    "Image100.242.jpg"    "Membrane-Stained Cells"
    "Image100.251.jpg"    "Membrane-Stained Cells"
    "Image100.252.jpg"    "No Cells"              
    "Image100.261.jpg"    "Membrane-Stained Cells"
    "Image100.262.jpg"    "Membrane-Stained Cells"
    "Image100.271.jpg"    "No Cells"              
    "Image100.272.jpg"    "No Cells"              
    "Image100.281.jpg"    "No Cells"              
    "Image100.282.jpg"    "Intracellular-Stained Cells"           

As you can see, there are three different categories of the images. I want to write these images into one of three folders, according to which category they belong to. For example, I want to write the first image into a folder called "Membrane-Stained Cells" and so on for all 3545 images.

How do I do this?

Thanks in advance.

Try something like

for k = 1 : size(namesandlabels, 1)
    outputFolder = namesandlabels(k, 2);
    thisBaseFileName = namesandlabels(k, 1);
    sourceFullFileName = fullfile(pwd, thisBaseFileName); % Assume the image is in this folder.
    destinationFullFileName = fullfile(outputFolder, thisBaseFileName); % In some other folder.
    copyfile(sourceFullFileName, sourceFullFileName);
end

Thanks for the answer and sorry for not responding earlier. This code doesn't work because it just says that it cannot copy a file onto itself.

Make sure your output folder is not the current folder. I bet that is what is happening. Make sure you have the right input folder and right output folder when you call fullfile().
