       nifti - IO libraries and tools for the NIFTI-1 data format


       The  NIfTI-1  data  format  is a binary file format for storing medical
       image data, e.g. magnetic resonance  image  (MRI)  and  functional  MRI
       (fMRI) brain images.

       The NIfTI format is an extension of the widely used ANALYZE 7.5 format.
       The goals of this modified data format are (1) to  add  information  to
       the  header  that  will  be  useful  for  functional  neuroimaging data
       analysis and display. These additions include:

              - More basic data types.
              - Two affine transformations to specify voxel coordinates.
              - "Intent" codes and parameters to describe the meaning  of  the
              -  Affine  scaling  of  the  stored  data values to their "true"
              - Optional storage of the header and  image  data  in  one  file

       And  (2)  To  maintain  compatibility  with non-NIFTI-aware ANALYZE 7.5
       compatible software  (i.e.,  such  a  program  should  be  able  to  do
       something useful with a NIFTI-1 dataset -- at least, with one stored in
       a traditional .img/.hdr file pair).

       The NIfTI library package consists of two libraries:

       znzlib -- low level  library  for  handling  read/write  of  compressed

       niftilib -- core i/o routines for reading and  writing  nifti-1  format
       files. Primarily routines to read/write and manipulate the header field
       information,    including    orientation    matrices.      Volume-wise,
       timecourse-wise, access to image data.


       nifti_tool(1), nifti1_test(1), nifti_stats(1).



       The NIfTI libraries were written by the NIfTI Data Format Working Group
       (DFWG, ).
