Hello all

I have two tiff images (named A and B). Both have 7 layers at the same dimension (4169,6289,7). First I'd like to find location of max value in A image and then I need to get the values (not max values, reall values) of B image in matrix dimension (4169, 6289) according to location of max value which found from A image in previous step. I just wrote next code to achieve this purpose. Then I wrote output tiff image. But when I display this tiff image, whole screen is black. Can you tell me what's wrong with this code?
A_max_loc=MAX(A,INDEX,DIMENSION=3)
B_val=B[INDEX]
write_tiff,'D:\Output_IDL\B_val_2000.TIF',B_val

Thank you so much
