Dilate a CIFTI file

Wraps wb_command -cifti-dilate to fill in zeros or missing data with values from nearby brainordinates.

Usage

cifti_dilate(
  cifti_in,
  direction = c("COLUMN", "ROW"),
  surface_distance,
  volume_distance,
  cifti_out,
  left_surface = NULL,
  right_surface = NULL,
  nearest = FALSE,
  verbose = get_wb_verbosity()
)

Arguments

cifti_in

Path to the input CIFTI file.

direction

Direction to dilate. One of "COLUMN" or "ROW".

surface_distance

Surface dilation distance in mm.

volume_distance

Volume dilation distance in mm.

cifti_out

Path for the output CIFTI file.

left_surface

Path to the left hemisphere surface.

right_surface

Path to the right hemisphere surface.

nearest

Logical; use nearest good value instead of weighted average?

verbose

Logical; print command output?

Value

The result of the underlying wb_cmd() call.

Examples

if (FALSE) { # \dontrun{
cifti_dilate(
  "data.dscalar.nii",
  direction = "COLUMN",
  surface_distance = 10,
  volume_distance = 10,
  cifti_out = "dilated.dscalar.nii",
  left_surface = "left.midthickness.surf.gii",
  right_surface = "right.midthickness.surf.gii"
)
} # }
