Glasser Surface Atlas (fsaverage)

Source: R/glasser.R
glasser_surf.Rd

Load the Glasser HCP-MMP1.0 cortical parcellation projected to the FreeSurfer fsaverage surface, as distributed by Kathryn Mills (see Figshare dataset "HCP-MMP1.0 projected on fsaverage"). The result is a pair of neurosurf LabeledNeuroSurface objects plus atlas metadata.

Usage

glasser_surf(
  space = "fsaverage",
  surf = c("pial", "white", "inflated", "midthickness"),
  use_cache = TRUE
)

Arguments

space

Surface space / mesh template. Only "fsaverage" is supported at present.

surf

Surface type. One of "pial", "white", "inflated", or "midthickness".

use_cache

Logical. Whether to cache downloaded annotation files in the neuroatlas cache directory. Default: TRUE.

Value

A list with classes c("glasser_surf","surfatlas","atlas") containing:

  • lh_atlas, rh_atlas: LabeledNeuroSurface objects for left and right hemispheres.

  • surf_type: requested surface type.

  • surface_space: surface template space ("fsaverage").

  • ids, labels, orig_labels, hemi, cmap: atlas metadata.

Details

This function uses:

  • fsaverage surface geometry from TemplateFlow via get_surface_template

  • fsaverage .annot files from the Mills Figshare distribution (lh.HCP-MMP1.annot, rh.HCP-MMP1.annot)

Currently only the "fsaverage" surface space is supported.

Examples

if (FALSE) { # \dontrun{
# Glasser MMP1.0 on fsaverage pial surface
atl <- glasser_surf(space = "fsaverage", surf = "pial")
} # }
