vtk.cell.section.layout

The cell arrays of VTK legacy files come in two layouts, see the
comment at the top of this file. Both layouts are still written by software
in use today, and the version number in the header does not reliably
indicate which one a file uses, so the layout is detected from the presence
of the OFFSETS keyword: the old layout starts the cell data with the vertex
count of the first cell as a raw number, whereas the new layout starts it
with the string 'OFFSETS'. For ASCII files that is simply the next line; for
binary files the first byte decides, and because a cell vertex count is a
small integer, the first byte of an old style cell array is always zero.

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.
