minc_downsample

Downsample a MINC volume by specified factors.

minc_downsample [options] <input> <output>

DESCRIPTION

minc_downsample reduces the resolution of a MINC volume by integer downsampling factors along each spatial dimension. Different factors can be specified independently for each axis, allowing for anisotropic downsampling. The tool performs appropriate averaging during downsampling.

OPTIONS

--verbose

Print progress information during processing.

--clobber

Overwrite existing output files.

--xfactor f

Set the downsampling factor along the X axis. Default: 1.

--yfactor f

Set the downsampling factor along the Y axis. Default: 1.

--zfactor f

Set the downsampling factor along the Z axis. Default: 2.

--factor f

Set the downsampling factor along the Z axis (same as --zfactor).

--3dfactor f

Set the same downsampling factor for all three axes.

--float

Write output in single-precision floating-point format.

--short

Write output in short integer format.

--byte

Write output in byte (unsigned char) format.

EXAMPLES

Downsample a volume by a factor of 2 in all dimensions:

minc_downsample --3dfactor 2 input.mnc downsampled.mnc

Downsample only in Z by a factor of 2 (default behavior):

minc_downsample input.mnc downsampled.mnc

Downsample with different factors per axis:

minc_downsample --xfactor 2 --yfactor 2 --zfactor 4 input.mnc downsampled.mnc
