<div>Dear Amjad,<br>I had a quick look at your dataset. For sure, it's a
geometry problem. Do you have any information regarding the geometry? How
did you obtain sdd / sid?<br>Currently, I can see that you have set the
projections and the volume origin to 0,0,0 which is not correct, you
probably want to center them for a first test. If you want to center them,
the formula to compute the origin is -0.5*spacing*(size-1) for each
corrdinate.<span><font color="#888888"><br>Simon</font></span>
