# mnc2nii(1)

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

## NAME

mnc2nii - convert a MINC format file to a NIfTI-1 or Analyze format file.

## SYNOPSIS

**mnc2nii** *\[\<options\>\] \<infile.mnc\> \<outfile.mnc\>*

**mnc2nii** *-help*

## DESCRIPTION

The  **mnc2nii** command is used to convert MINC format files to either NIfTI-1 or Analyze 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.

In addition to the NIfTI-1 formats,  **mnc2nii** can convert MINC files to the Analyze 7.5 format.

## OPTIONS

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

## Output file format

- **-dual**

  Save file in NIfTI-1 two-file format (.hdr and .img)

- **-ASCII**

  Save file in non-standard NIfTI-1 ASCII file format

- **-nii**

  Save file in NIfTI-1 single-file format (.nii)

- **-analyze**

  Save file in Analyze 7.5 compatible format

## Output voxel format

- **-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**

  Save voxels in unsigned integer format

## Other options

- **-noscanrange**

  Don't scan data to determine valid range.

- **-quiet**

  Quiet operation - do not print progress or debugging information.

## Generic options for all commands

- **-help**

  Print summary of command-line options and abort

- **-version**

  Print the program and library versions and abort

## KNOWN BUGS

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.
