== General description ==

'''NII''' (or NIfTI) files are probably the most commonly-used format for multi-dimensional neuroimaging data as of this writing (late 2012). NIfTI is a raster format, with files generally containing at least 3-dimensional data: voxels, or pixels with a width, height, and depth. NIfTI files can be up to 7-dimensional: the first four dimensions are defined as 3 spatial dimensions and time, with the other dimensions used for "other stuff" -- though the time dimension is often to encode something other than time.

Most packages also support reading gzip-compressed NIfTI files, which should have the extension '''.NII.gz'''.

The format is extensively supported and [http://nifti.nimh.nih.gov/ documented by the NIH].

== Software ==

* [http://nifti.nimh.nih.gov/nifti-1/ NIH Documentation] and [http://nifti.nimh.nih.gov/pub/dist/src/niftilib/nifti1.h reference C header]
* [http://niftilib.sourceforge.net/ NiftiLib], a full C implementation
* [http://nipy.sourceforge.net/nibabel/ NiBabel], a Python neuroimaging file format library
