-The SEGMENT command process a 3-D image map looking for voxel values greater than 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.  Cluster values start at 1, and increase by 1 for each new cluster found.

 VALUE: default is 0
 FLAG:\\
-- default
+- default\\
 - look for negative voxel values, less than -VALUE
