cifti.nifti.header.for.axes

CIFTI-2 files are NIFTI-2 files whose header has a fixed shape: the matrix
dimensions are stored in the <code>dim</code> field (dimension 0 in <code>dim[5]</code>, dimension 1 in
<code>dim[6]</code>, which is why <code>dim[0]</code> is 6 for a two-dimensional matrix), the intent code
names the file type, the voxel sizes, the scaling and the geometry fields are unused
(the geometry of a CIFTI-2 file is in its XML), and the data start after the header
extension that holds the XML.

Provides functions to read and write neuroimaging data in various file formats, with a focus on 'FreeSurfer' formats. This includes, but is not limited to, the following file formats: 1) MGH/MGZ/NIFTI format files, which can contain multi-dimensional images or other data. Typically they contain time-series of three-dimensional brain scans acquired by magnetic resonance imaging (MRI). They can also contain vertex-wise measures of surface morphometry data. The MGH format is named after the Massachusetts General Hospital, and the MGZ format is a compressed version of the same format. 2) 'FreeSurfer' morphometry data files in binary 'curv' format. These contain vertex-wise surface measures, i.e., one scalar value for each vertex of a brain surface mesh. These are typically values like the cortical thickness or brain surface area at each vertex. 3) Annotation file format. This contains a brain surface parcellation derived from a cortical atlas. 4) Surface file format. Contains a brain surface mesh, given by a list of vertices and a list of faces.
