For example, now I have two segmentation documents.  
But when I click the save button I only get one document.  
How can I save them seperately?  
Thanks a lot!

The `Segmentation.seg.nrrd` extension saves the segmentation node, including both segments `(Segment_1, Segment_2)`, and a reference to the master volume used for the segmentation `(6 1st ax dyn)`

Thanks, is it possible to save them separately?  
Because I want to do an analysis of these two segmentation independently and jointly.

@LIE_CAI,

Quick and dirty: Clone the segmentation node and erase the segments you don’t need on each respective copy. You will end-up with multiple segmentations nodes with only one segment, in your case.

Keep in mind that any relevant analysis is tied to the `master volume`. So ensure that each “cloned” node has the right `master volume` assigned.

Got that. But how to clone the segmentation node?  
Just repeating the segment process would be waste of time…

Right click, clone node!

Hmmm, I still have not found the clone node button.  
But I found a way to achieve it.  
First, click “Segmentations…”

Then click “Copy/move segments”,

Then choose “Create new Segmentation”.  
In this way, I can get two “segmentation. nrrd” documents and save them separately.😋
