vbregion
From VoxBoWiki
vbregion prints basic information about regions in 3D stat volumes. Its minimal functionality really needs to be merged with some other programs, but in the meantime, here's the help text:
VoxBo vbregion (v1.8.5pre8/May 6 2010) summary: region info usage: vbregion [<flags>] <cube> ... flags: -t <thresh> include voxels where value > threshold -a <thresh> include voxels where abs(value) > thresh -m <mask> notes: The default threshold is -t 0 (include all positive voxels).
