<DIV>Hi Luis,</DIV>
<DIV> </DIV>
<DIV>Thanks for your instruction.</DIV>
<DIV> </DIV>
<DIV>I tried to set region to the fixed image by setting </DIV>
<DIV> start[2]=size[2]/2 and size[2]/=2 immediately after reading the image.</DIV>
<DIV> </DIV>
<DIV>I use the Mattes MI metric and Centered Rigid 3D image transformation.</DIV>
<DIV> </DIV>
<DIV>But every time I tried to run the .exe, it always told me there are too many samples outside the moving image. And I choose a smaller number for number of samples. I still got the same exception.</DIV>
<DIV> </DIV>
<DIV>Why should this happen? </DIV>
<DIV>It works well before I set the region.</DIV>
<DIV> </DIV>
<DIV>Best Regards,</DIV>
<DIV> </DIV>
