FreesurferAtlases: Coordinates for data from Freesurfer atlases

Description

Datasets containing spatial coordinates for the Freesurfer atlases: Destrieux, Desikan-Killiany (DK), and Desikan-Killiany-Tourville (DKT). The datasets also contain indices for the major lobes and hemispheres of the brain, in addition to the class variable for Destrieux atlases.

Usage

destrieux

destrieux.scgm

dk

dk.scgm

dkt

dkt.scgm

Arguments

Format

A data frame with 148 or 162 (for Destrieux), 68 or 82 (for DK), or 62 or 76 (for DKT) observations on the following 8 variables:

name

a character vector of region names

x.mni

a numeric vector of x-coordinates (in MNI space)

y.mni

a numeric vector of y-coordinates (in MNI space)

z.mni

a numeric vector of z-coordinates (in MNI space)

lobe

a factor with levels Frontal, Parietal, Temporal, Occipital, Insula, Limbic, and SCGM (for atlases ending in .scgm)

hemi

a factor with levels L R

index

a numeric vector

name.full

a character vector of full region names, for the DK and DKT atlases

class

a factor with levels G G_and_S S
