NIfTI-1 Image Data Format Announcement
We are writing on behalf of the Data Format Working Group (DFWG), a 
committee set up under the Neuroimaging Informatics Technology 
Initiative (NIfTI, http://nifti.nimh.nih.gov), which is jointly 
sponsored by NIMH and NINDS. We have been charged with arriving "at a 
technical solution to the problem of multiple data formats in fMRI." We 
have met several times and decided that one of our first priorities is 
to describe and attempt to merge the variants of the ANALYZE(TM) 7.5 
image header that are being used by the developers of the major fMRI 
data analysis packages.

We have defined a compromise data format, dubbed NIfTI-1, that is based 
on these variants and is "mostly compatible" with the ANALYZE(TM) 7.5 
header, while using many of the "unused and lesser-used" fields for 
fMRI-specific purposes. Developers of five of the major fMRI data 
analysis packages (FSL, SPM, AFNI, BrainVoyager, and FreeSurfer) have 
agreed to use this compromise format in the future, and will support 
both input and output of the NIfTI-1 format. A considerable effort was 
required to reach agreement with all of these developers. Given the 
extremely limited space in the 348 byte header, it is unlikely that any 
substantial changes will be possible in the NIfTI-1 format if we are to 
retain the support of all five packages.

We envisage NIfTI-1 replacing the current range of ANALYZE 7.5 variants 
both for file interchange and data storage.  NIfTI-1, while still 
limited, contains a considerably richer set of metadata than exists in 
the ANALYZE-based formats.

As of this message, the NIfTI-1 format specification, demonstration 
programs, and related documents are being released to the general 
neuroimaging community on the DFWG website
   http://nifti.nimh.nih.gov/dfwg/
along with an interactive forum for comments and discussion. The DFWG 
committee will next meet in early May 2004, and any comments you care 
to make and would like to have considered at the next committee meeting 
should be received by April 15, 2004.

Please feel free to pass this message along to any other person you 
think might be interested.  Comments and questions should be directed 
to the NIfTI-1 interactive forum, and not to DFWG committee members via 
e-mail.  The full list of DFWG committee members can be found at the 
DFWG website.
