Compute binarized mean curvature surface color layer.

Compute a binarized mean curvature surface color layer, this is intended as a background color layer. You can merge it with your data layer using collayers.merge.

Usage

collayer.bg(subjects_dir, subject_id, bg, hemi = "both")

Arguments

subjects_dir

character string, the FreeSurfer SUBJECTS_DIR.

subject_id

character string, the subject identifier.

bg

character string, a background name. One of 'curv', 'curv_light', 'sulc', 'sulc_light', or 'aparc'. If this is already a colorlayer in a hemilist, it will be returned as-is.

hemi

character string, one of 'lh', 'rh', or 'both'. The latter will merge the data for both hemis into a single vector.

Value

a color layer, i.e., vector of color strings in a hemilist

You can plot the return value using vis.color.on.subject.
