save images into folder

hi guys, I have this problem i have been trying to fix without any success. I would be grateful if you could give it a look.

I have few images (4) all named like this: a_484 , a_485, a_486, a_487. All images are the same.

The first part of the script works just fine but i cant save the new images as i would like.

for example: let's say for each image matlab generates the picture of 10 bouding boxes. I would like to save those bounding box images in a new folder likewise: a_484_1, a_484_2, a_484_3, a_484_4, ..., a_484_10 - a_485_1, a_485_2, a_485_3, etc etc for each of them.

I will attach my script.

dirName = uigetdir('./', 'Select data folder');
cd(dirName); 
for i=484:487 % numero layers esaminati
   image_{i}=imread(sprintf('a_%03d.tif',i));
   BW=image_{i}>3500;
   figure,imshow(BW);
   labeledImage = bwlabel(BW);
   measurements = regionprops(labeledImage, 'BoundingBox', 'Area');
      for k = 1 : length(measurements)
        thisBB = measurements(k).BoundingBox;
        image2_{i}=imcrop(image_{i},[thisBB(1),thisBB(2),thisBB(3),thisBB(4)]);
        [rows cols depth]=size(image2_{i});
            
            if rows*cols>100
                figure,imshow(image2_{i});
                colormap (jet) 
                colorbar 
                caxis([0 45000]);
                axis on   
            end
            
      end
     
       baseFileName = sprintf('a_%03d_%k.tif', i, k);
       fullFileName = fullfile('C:...\new', [baseFileName, num2str(i),'.tif']);
       imwrite(image2_{i},fullFileName) 

end

       baseFileName = sprintf('a_%03d_%k.tif', i, k);
       fullFileName = fullfile('C:...\new', [baseFileName, num2str(i),'.tif']);

%k is not a valid % sequence. You should be using

       baseFileName = sprintf('a_%03d_%d.tif', i, k);
       fullFileName = fullfile('C:...\new', baseFileName);

but with C:...\new replaced with something meaningful
