vol.vol2surf.hemilist: Project a volume onto the vertices of the given surfaces (internal workhorse).

Description

Project a volume onto the vertices of the given surfaces (internal workhorse).

Usage

vol.vol2surf.hemilist(
  surfaces,
  volume,
  default_dir,
  interpolation,
  frame,
  clamp,
  check_fov,
  affine = NULL,
  vox2ras = "auto"
)

Value

named list of numeric vectors (one per hemisphere), with attribute 'outside' (named list of logical vectors or NULLs).

Arguments

surfaces

named list of vertex coordinate matrices, per hemisphere.

volume

the volume, as accepted by vol.load.

default_dir

character string or NULL, the directory used to resolve volume names without extension.

interpolation

character string, see subject.vol2surf.

frame

integer scalar, see subject.vol2surf.

clamp

logical, whether to clamp query points outside the volume to the volume border.

check_fov

logical, whether to check (and warn about) vertices outside the volume.

affine

numeric 4x4 matrix or NULL, used instead of the affine matrix from the volume header if given.

vox2ras

character string, see subject.vol2surf.
