I have a structure of images and I want to make some processing on them. I put them on a list but when I try to save each one of them(I'm using a for loop to make the processing) the code reads the first element of the structure and then it goes straight to the end without reading the rest. Here's my code

 imglist=dir('*.tif');   %list of the .tif images
 for i=1,length(imglist)
    name=getfield(imglist(i),'name');
    A=imread(name);
    level(i)=graythresh(A);   %level of the threshold for Otsu method
    BI=im2bw(A,level(i));    %converts the grayscale image to a binary image
    thresh(:,:,i)=BI;    %save the thresh image
    BIedge=edge(BI,'Canny'); %edge detection with Canny method
    imshow(BIedge)
    edges_canny(:,:,i)=BIedge;
    f=figure;
    imshow(BI);
    saveas(f,sprintf('thresh8B-3.2_15k_0d5_base_x=0mm_y=0mm_C001H001S000100000%d.tif',i))
    f=figure;
    imshow(imfill(edges_canny(:,:,i),'holes'));
    saveas(f,sprintf('canny8B-3.2_15k_0d5_base_x=0mm_y=0mm_C001H001S000100000%d.tif',i))
 end
