annot.outline.border.vertices: Compute the border vertices for each region in an annot.

In fsbrain: Managing and Visualizing Brain Surface Data

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.
