In fsbrain: Managing and Visualizing Brain Surface Data

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"
)

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.

Value

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