Hi,
I have 5 radiologists who classified tumors in 3 stages (Stage 1, Stage 2, Stage 3). They did the classification manually putting numbers 1 = Stage 1 , 2 = Stage 2 and 3 = Stage 3 on each region. Each patient has about 10-14 tumors. For each patient I want to see how many tumors they classified the same. How can I do that?

I used the imread to load the images as you suggested.
Then I used the and function but I got the following error:
im1 = imread('im1.png');
im2 = imread('im2.png');
im3 = imread('im3.png');
im4 = imread('im4.png');
im5 = imread('im5.png');
and(im1,im2,im3,im4,im5)
Error using &
Too many input arguments.
Did I use the and function wrongly?
