Compute geodesic distance from a vertex

Wraps wb_command -surface-geodesic-distance to compute the geodesic distance from a single vertex to all other vertices on a surface.

Usage

surface_geodesic_distance(
  surface_in,
  vertex,
  metric_out,
  limit = NULL,
  corrected_areas = NULL,
  verbose = get_wb_verbosity()
)

Arguments

surface_in

Path to the input surface file.

vertex

Index of the source vertex (0-indexed).

metric_out

Path for the output metric file.

limit

Maximum geodesic distance in mm. Vertices beyond this distance get value -1.

corrected_areas

Path to a metric file of corrected vertex areas (for group-average surfaces).

verbose

Logical; print command output?

Value

The result of the underlying wb_cmd() call.

Examples

if (FALSE) { # \dontrun{
surface_geodesic_distance(
  "lh.midthickness.surf.gii",
  vertex = 0,
  metric_out = "geodesic.func.gii",
  limit = 100
)
} # }
