subsample_volume

subsample a MINC volume by taking every nth voxel in each dimension

subsample_volume input.mnc output.mnc nx ny nz

DESCRIPTION

subsample_volume reduces the resolution of a MINC volume by taking every nx-th voxel along the x-axis, every ny-th voxel along the y-axis, and every nz-th voxel along the z-axis. The output volume has correspondingly fewer voxels in each dimension while preserving the spatial extent and coordinate system of the original volume.

This is a simple decimation operation without interpolation or anti-aliasing filtering.
