MATLAB: Imread and/or rgb2gray not working as expected

[RGB, map, alpha] = imread('Cir1.png');
 figure ; imshow(RGB,map);
   [rows, columns, numberOfColorChannels] = size(RGB);
   if numberOfColorChannels > 1
     Igray = rgb2gray(RGB);
   else
     Igray = rgb2gray(map); 
   end
   figure ;imshow(RGB,Igray);

MATLAB: Matlab imshow

this gives an error with imsubstract because the images are not of the same size.
