Operating system: Windows 10  
Slicer version: Slicer 4.10.1  
Expected behavior:

 ![Table%20generated%20by%20Segment%20Statistics](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/2/d/2d983b2657dd6bd521aec52d4fb85f514fdd9655.png)  
Actual behavior:

I draw ROIs manually using Segment Editor module, and then calculate the ROI volumes using Segment Statistics.  
The attached Table appeared after the calculation.  
I would like to know whether the ROI volumes, which I need, are in the column named Volume (mm3) (1) or that named Volume (mm3) (2).  
In addition, I would like to know the difference between Volume (mm3) (1) and Volume (mm3) (2), and the meaning of them.  
I appreciate your time and kind advice.

> Hi! I have a question regarding the module Segment Statistics. After applying Segement Statistics in 3DSlicer 4.9, 3DSlicer displays two different volumes, volume (1) and (2). Please find the attached table here: [image] What is the difference between these volumes? Thanks!

Dear Dr. Andras Lasso,

Thank you for your kind information.  
I could understand the difference between them.

Best,
