NAME¶
nifti - IO libraries and tools for the NIFTI-1 data format
DESCRIPTION¶
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
data.
- Affine scaling of the stored data values to their "true" values.
- Optional storage of the header and image data in one file (.nii).
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
files.
-
- 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.
