 +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:\\
 + 0 - default\\
 + 1 - also look for negative voxel values, less than or equal to -VALUE (default is just positive)
