vbmaskinfo

From VoxBoWiki

vbmaskinfo takes as input a 4D volume in which each "time" point is a lesion mask. It prints a summary of the lesion masks, including a count of the number of distinct voxels and a breakdown of the number of voxels with different lesion counts.

Here's the help text:

notes:
  vbmaskinfo treats all the passed 3D and 4D volumes as one
  large series of masks, typically lesion masks, and produces
  a summary of the number of total and distinct voxels in the
  combined volume.
