<div class="textblock"><p>Data structure defining the fields in the nifti1 header. This binary header should be found at the beginning of a valid NIFTI-1 header file. </p>
<p>INTRODUCTION TO NIFTI-1: ------------------------ The twin (and somewhat conflicting) goals of this modified ANALYZE 7.5 format are: (a) To add information to the header that will be useful for functional neuroimaging data analysis and display. These additions include:</p>
<ul>
<li>More basic data types.</li>
<li>Two affine transformations to specify voxel coordinates.</li>
<li>"Intent" codes and parameters to describe the meaning of the data.</li>
<li>Affine scaling of the stored data values to their "true" values.</li>
<li>Optional storage of the header and image data in one file (.nii). (b) 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).</li>
</ul>
<p>Most of the unused fields in the ANALYZE 7.5 header have been taken, and some of the lesser-used fields have been co-opted for other purposes. Notably, most of the <a class="el" href="structdata__history.html">data_history</a> substructure has been co-opted for other purposes, since the ANALYZE 7.5 format describes this substructure as "not required".</p>
<p>NIFTI-1 FLAG (MAGIC STRINGS): ---------------------------- To flag such a struct as being conformant to the NIFTI-1 spec, the last 4 bytes of the header must be either the C String "ni1" or "n+1"; in hexadecimal, the 4 bytes 6E 69 31 00 or 6E 2B 31 00 (in any future version of this format, the '1' will be upgraded to '2', etc.). Normally, such a "magic number" or flag goes at the start of the file, but trying to avoid clobbering widely-used ANALYZE 7.5 fields led to putting this marker last. However, recall that "the last shall be first" (Matthew 20:16).</p>
<p>If a NIFTI-aware program reads a header file that is NOT marked with a NIFTI magic string, then it should treat the header as an ANALYZE 7.5 structure.</p>
<p>NIFTI-1 FILE STORAGE: -------------------- "ni1" means that the image data is stored in the ".img" file corresponding to the header file (starting at file offset 0).</p>
<p>"n+1" means that the image data is stored in the same file as the header information. We recommend that the combined header+data filename suffix be ".nii". When the dataset is stored in one file, the first byte of image data is stored at byte location (int)vox_offset in this combined file. The minimum allowed value of vox_offset is 352; for compatibility with some software, vox_offset should be an integral multiple of 16.</p>
<p>GRACE UNDER FIRE: ---------------- Most NIFTI-aware programs will only be able to handle a subset of the full range of datasets possible with this format. All NIFTI-aware programs should take care to check if an input dataset conforms to the program's needs and expectations (e.g., check datatype, intent_code, etc.). If the input dataset can't be handled by the program, the program should fail gracefully (e.g., print a useful warning; not crash).</p>
<p>SAMPLE CODES: ------------ The associated files <a class="el" href="nifti1__io_8h.html" title="Data structures for using nifti1_io API.">nifti1_io.h</a> and <a class="el" href="nifti1__io_8c.html" title="main collection of nifti1 i/o routines">nifti1_io.c</a> provide a sample implementation in C of a set of functions to read, write, and manipulate NIFTI-1 files. The file nifti1_test.c is a sample program that uses the <a class="el" href="nifti1__io_8c.html" title="main collection of nifti1 i/o routines">nifti1_io.c</a> functions. ----------------------------------------------------------------------------- </p>
