Hi, I’m trying to change the resolution of a segmentation to then use a grow filter to adapt it to the vessel structures of my CTs. My problem is that, when setting any oversampling factor, my segmentation seemingly disappears. Why is that and how could I solve it?  
Thanks in advance.

What if drag the segmentation in Data module to the Slice view windows?
