Hi everybody,  
I am using 3Dslicer4.10 on windows 10 and I am experiencing a strange behaviour when I want to quantify voxels content values after registration between 2 images.  
In short:  
2 volumes are registrated with 2 procedures (rigid, non-rigid). I rapidly segmented one of 2 with `Editor tool` to get a labelmap with just one label. To get counts inside my label, I used `Label statistics`. Swaping the transform on registrated image doesn’t affect results in `label statitics` whereas it does so when performing the same operation by importing the labelmap in `Segment editor tool`. Do I missed something ?  
Here is a bundle that contains the 2 datasets and registration transform: [https://uncloud.univ-nantes.fr/index.php/s/pmryzmKNgstyHGE](https://uncloud.univ-nantes.fr/index.php/s/pmryzmKNgstyHGE)

Best wishes  
Ludovic

Editor module has many limitations (for example the one that you have noticed). Use Segment Editor module and Segment Statistics modules instead.

Thank you Andras, I finally came to the same conclusion.
