nii2mnc - convert a NIfTI-1 or Analyze 7.5 format file to a MINC format file.

nii2mnc [<options>] <infile> <outfile.mnc>

nii2mnc -help

The nii2mnc command is used to convert "NIfTI-1" format files to MINC format. The NIfTI-1 format was developed by the members of the Neuroinformatics Technology Initiative's Data Format Working Group (DFWG). The NIfTI-1 format is based upon the Mayo Clinic's Analyze 7.5 format.

The name of the program is derived from the common filename suffixes used for NIfTI-1 and MINC files. NIfTI-1 defines two possible formats, a "header plus raw image" 2-file format, and a single-file format that includes both header information and the image data. As with Analyze 7.5, the 2-file format consists of one file with the suffix ".hdr" and another file with the extension ".img". In NIfTI-1 single-file format, the two files may be combined into a single file with a ".nii" filename suffix.

Note that options can be specified in abbreviated form (as long as they are unique) and can be given anywhere on the command line.

-float

Save voxels in 32-bit floating point format

-double

Save voxels in 64-bit floating point format

-byte

Save voxels in 8-bit integer format

-short

Save voxels in 16-bit integer format

-int

Save voxels in 32-bit integer format

-signed

Save voxels in signed (2's complement) integer format

-unsigned

-noscanrange

Don't scan data to determine valid range.

-quiet

Quiet operation - do not print progress or debugging information.

-help

Print summary of command-line options and abort

-version

Print the program and library versions and abort

Current handling of NIfTI-1 qform and sform coordinate transforms should probably be revised as the NIfTI group clarifies the correct usage of these fields.
