Normalize a CIFTI brain structure name.

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

Usage

cifti.structure.canonical(brain_structure)

Arguments

brain_structure

character string, a brain structure name in any of the supported spellings.

Value

character string, the canonical structure name (e.g. 'CIFTI_STRUCTURE_CORTEX_LEFT'), or NA_character_ if the input is NA.
