Hi cagatay
really thanks for trying to help me actually the problem is solved , you are
right from the beginning.
viewer rescale intensity from min to max value i set i mean from 50---1100
so when i set one pixel to max intensity found in the original image all
things going well .
by the way data set 75 mb so it's too large to upload with my bad internet
connection sorry.
and thanks very much.
