I tried to convert a 48*48 gray image into pixels values, now i tried to convert it back into gray image, but the converted image is not showing properly, it show the upper portion of face below and below portion above.

my code is:

X = importdata('i2.txt');
d = reshape( uint8(X), 48, 48);
better_d = d([40:end,1:39],[25:end, 1:24]).';
image(better_d); colormap(gray(256));

saeeda - please comment on this line of code

 better_d = d([40:end,1:39],[25:end, 1:24]).';

Why are you trying to do here?

And attach i2.txt so we can try your code.
