-**fScan Reference Manual, Chapter 2 (CmdLineOptions:Expr): segment**
-===== segment -- Assign contiguous voxels with similar values to different clusters =====
- **usage:  -expr segment [value flag]**\\
-The SEGMENT command process a 3-D image map looking for voxel values greater than or equal to VALUE.  Each time it finds such a voxel it uses a variation of the [[jvs:fscan:manual:chapter2:expression:flood|flood]] function to find all other voxels greater than VALUE contiguous with the first, and assigns all those values a new "cluster" number.  Clusters can have as few as 1 voxel. Cluster values start at 1, and increase by 1 for each new cluster found.
-VALUE: default is 1
-FLAG:\\
-- default\\
-- also look for negative voxel values, less than or equal to -VALUE (default is just positive)
