Sir, In the above code, the first click point checks the first image in a folder and if I select the next click point, it does not compare with the second click point rather automatically compares with the first image i.e. a1 and the second image in a folder. Please solve my issue as early as possible.

function [pts]=ImageClickCallback4 ( str1,a1,a2,a3,a4,a5,a6,n1)
  global ii;
  ii=1;
  a1=rgb2gray(a1);
  a2=rgb2gray(a2);
  a3=rgb2gray(a3);
  a4=rgb2gray(a4);
  a5=rgb2gray(a5);
  a6=rgb2gray(a6);
  image_folder = 'C:\Users\maruthi1\Documents\MATLAB\User_reg\'
  image_folder=strcat(image_folder,str1);
  filenames = dir(fullfile(image_folder, '*.jpg'));  % read all images with specified extention, its jpg in our case
   total_images = numel(filenames);  
   if(~isequal(total_images,n1))
       message     = sprintf('Please enter correct number');
  helpdlg(message); 
    end
     for n = 1:total_images
      full_name= fullfile(image_folder, filenames(n).name);         % it will specify images names with full path and extension
      our_images = imread(full_name); 
      our_images=rgb2gray(our_images);
    %subplot(3,3,n);
       % imshow(our_images) ;                 % Show all images
     end
     pts = zeros(2, n1);
         % display image
    xold = 0;
    yold = 0;
    k = 0;
    hold on;  
    mp1=340;
    % and keep it there while we plot
    while 1
           [xi, yi, but] = ginput(1);      % get a point
        if ~isequal(but, 1)             % stop if not button 1
            break
        end
        k = k + 1;
        pts(1,k) = xi;
        pts(2,k) = yi;
