The dataset consists of 5 files/slices, all containing zero's and one's.
The goal is to take a 5x5x5 volume that contains an object in the center
cell and extract that object.  

Data Spacing is set to:  volReader->SetDataSpacing(1,1,1);

Thanks,
Vetria

Vetria,

	What type of image are you reading ? Is it possible that you have a 
negative spacing ? You might to avoid this.
