cifti.surface.vertex.count

Get the size of the complete surface a brain model refers to. The
<code>Surface</code> elements of the mapping are used if the file has them, otherwise
the <code>SurfaceNumberOfVertices</code> attributes of the brain models are used: the
<code>Surface</code> elements are optional, and the files written by Connectome
Workbench (including the official CIFTI-2 example files) do not contain any,
they report the surface size in the brain models only.

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.
