annot.outline.border.vertices {fsbrain}

Compute the border vertices for each region in an annot.

Description

Compute the border vertices for each region in an annot.

Usage

annot.outline.border.vertices(
  annotdata,
  surface_mesh,
  silent = TRUE,
  expand_inwards = 0L,
  limit_to_regions = NULL
)

Arguments

annotdata

an annotation, as returned by functions like subject.annot. If a character string, interpreted as a path to a file containing such data, and loaded with freesurferformats::read.fs.annot

surface_mesh

brain surface mesh, as returned by functions like subject.surface or read.fs.surface. If a character string, interpreted as a path to a file containing such data, and loaded with freesurferformats::read.fs.surface

silent

logical, whether to suppress status messages.

expand_inwards

integer, additional thickness of the borders. Increases computation time, defaults to 0L.

limit_to_regions

vector of character strings or NULL, a list of regions for which to draw the outline (see get.atlas.region.names). If NULL, all regions will be used. If (and only if) this parameter is used, the 'outline_color' parameter can be a vector of color strings, one color per region.

Value

named list, the keys are the region names and the values are vectors of integers encoding vertex indices.
