Read CIFTI annotation file

Reads a CIFTI dense label file (.dlabel.nii) and extracts region information for both hemispheres. Returns data in the same format as read_annotation_data() for use with the cortical atlas pipeline.

Usage

read_cifti_annotation(cifti_file)

Arguments

cifti_file

Path to a .dlabel.nii CIFTI file.

Value

A tibble with columns: hemi, region, label, colour, vertices

Details

The CIFTI file must be in fsaverage5 space (10,242 vertices per hemisphere). If your file uses a different resolution, resample it first with Connectome Workbench:

wb_command -cifti-resample input.dlabel.nii ...

Examples

if (FALSE) { # \dontrun{
atlas_data <- read_cifti_annotation("parcellation.dlabel.nii")
} # }
