Hi,

The attached picture is from 3D slicer version 4.9.0. It shows a fast marching effect.

 ![3dslicer4.9.0](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/3/1/31207ad1e13509a2b8564776a6592440ff722dc7.png)  
How to access that FAST MARCHING effect or Button in the 3D slicer version 5.0.1 or 5.0.2 ?

Fast marching effect is available in the Segment Editor module after installing SegmentEditorExtraEffects extension.
