cifti.matrix.dim.sizes

The CIFTI-2 matrix dimensions 0, 1, ... are stored in the
<code>dim</code> field of the NIFTI-2 header, starting at its 6th entry (R index
vectors are 1-based, so matrix dimension 0 is entry 6). The dimension order
in the XML refers to matrix dimensions, so a <code>MatrixIndicesMap</code> with
<code>AppliesToMatrixDimension="0"</code> describes the 6th entry of <code>dim</code>.

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.
