I'm cropping some files and I want to keep the labels of the input files in the output files. Any idea to achieve that please.

imgFolderStokes = fullfile('Data/Stokes_Parameters/');
imgStokes = imageDatastore(imgFolderStokes);
numOfImgStokes = length(imgStokes.Files);
for ii = 1:numOfImgStokes
    Stokes{ii} = fitsread(imgStokes.Files{ii})
    targetSize = [244 234];
    r = centerCropWindow2d(size(Stokes{ii}),targetSize);
    J = imcrop(Stokes{ii},r);
    fitswrite(J,'myfile.fits')
end

hello

my 2 cents suggestion :

imgFolderStokes = fullfile('Data/Stokes_Parameters/');
imgStokes = imageDatastore(imgFolderStokes);
numOfImgStokes = length(imgStokes.Files);
for ii = 1:numOfImgStokes
    input_filename = imgStokes.Files{ii};
    Stokes{ii} = fitsread(input_filename)
    targetSize = [244 234];
    r = centerCropWindow2d(size(Stokes{ii}),targetSize);
    J = imcrop(Stokes{ii},r);
    
%     % if input_filename contains a dot plus a 3 letters extension,
%     % uncomment this line bellow : 
%     input_filename = input_filename(1:length(input_filename)-4);  % optionnal 
    
    fitswrite(J,[input_filename '_out.fits'])
end

outputdir = fullfile('Output_Fits');
if ~isdir(outputdir); mkdir(outputdir); end
stuff
fitswrite(J, char( fullfile(outputdir, input_file+"_out.fits")))

I still have the same error even though with char. Here's the code that I 'm trying to make it work:

imgFolder = fullfile('/ircnn_color/');
img = imageDatastore(imgFolder);
numOfImg = length(img.Files);
outputdir = fullfile('/results_convert_fits/');
for ii = 1:numOfImg
    input_filename = img.Files{ii};
    image = imread(input_filename,'png');
   
    fitswrite(image, char(fullfile(outputdir, input_filename+"_out.fits")))
    
end
