ERROR while creating GLCM

% input image is obtained by stacking different bands(4,3,2)
I=imread('D:\project\stack.tif');
G=rgb2gray(I);
figure
imshow(G)
offsets=[0 1;-1 1; -1 0;-1 -1];
glcm=graycomatrix(G,'offset',offsets)
stats=graycoprops(glcm)

=>obtained WARNING is 'image is too big to fit 'and glc matrix is not produced along with its statistics

my grey image is of size 7438x7575 uint8

i have seen a suggested answer:-

imshow(G, 'InitialMagnification', 'fit')

but returns same warning

if i use resize command,will image loses its actual information? as i want to classify the features obtained.

Change

imshow(G)

to

image(G)
colormap(gray(256));

if i use resize command,will image loses its actual information? as i want to classify the features obtained.

The size you display the image on the screen will not affect glcm analysis.

Sorry I have no information on that topic.
