Brace indexing is not supported for variables of this type.

Hi I need some help. I have created this for loop to extract the images in the different subfolders that are in the given directory in order to process them in another script called Feat_extraction_k. The loop does fine for the first subfolder and the images inside. However, once it reaches the second subfolder the error is displayed for the line with the variable 'Image File' (Brace indexing is not supported for variables of this type) How can I fix this? Thanks.

Try this:

filePattern = fullfile(pwd, '*.png');
imds = imageDatastore(filePattern)
allFileNames = imds.Files;
numFiles = numel(imds.Files);
for k = 1 : numel(allFileNames)
    % Get this file name.
    fullFileName = allFileNames{k};
    fprintf('Processing %s\n', fullFileName);
end

You can set the top level folder in the first line of the code above by replacing pwd with some folder of your own.

Thank you so much, this was really helpful! I used this code inside my initial for loop and worked perfectly :)
