cifti.structure.canonical

CIFTI brain structure names are written in several spellings by
different software: Connectome Workbench uses <code>CIFTI_STRUCTURE_CORTEX_LEFT</code>,
nibabel also accepts <code>CortexLeft</code>, and this package uses the aliases <code>lh</code> and
<code>rh</code> (and also <code>left</code>/<code>right</code>) for the cortical surfaces. This function
normalizes all of them to the canonical <code>CIFTI_STRUCTURE_*</code> spelling.

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.
