get_tic

compute statistics for spherical regions in a MINC volume

get_tic filename.mnc x y z v|w [radius1] [radius2] [radius3]

DESCRIPTION

get_tic computes the minimum, maximum, mean, standard deviation, and median for a spherical region centred at a given position in a MINC volume. Positions are specified in voxel coordinates (with v) or world coordinates (with w). Up to three radii may be specified to define the sphere axes; if fewer are given, the region defaults to a single voxel or a sphere with the given radius.

OPTIONS

This tool uses positional arguments only. There are no named options.

filename.mnc

The input MINC volume.

x y z

The centre position of the spherical region.

v|w

Coordinate system: v for voxel coordinates, w for world coordinates.

radius1

Optional radius of the sphere along the first axis.

radius2

Optional radius along the second axis.

radius3

Optional radius along the third axis.

EXAMPLES

Get statistics at voxel (50, 60, 70):

get_tic volume.mnc 50 60 70 v

Get statistics at world (10, -20, 30) with radius 5mm:

get_tic volume.mnc 10 -20 30 w 5
