In dfsp-spirit/regfusionr: Registration Fusion in R

Find MNI152 coordinate of fsaverage vertex closest to the given MNI305 coordinate.

Description

Find MNI152 coordinate of fsaverage vertex closest to the given MNI305 coordinate.

Usage

mni305_coords_to_mni152_coords(
  coords,
  surface = "orig",
  fs_home = Sys.getenv("FS_HOME"),
  simplify = FALSE
)

Arguments

coords	nx3 numerical matrix, the MNI305 query coordinates.
surface	a character string defining the fsaverage surface to load (like "white" or "orig"), or a pre-loaded hemilist of surfaces (i.e., freesurferformats::fs.surface instances)
fs_home	character string, path of the FreeSurfer directory from which the fsaverage surfaces should be loaded. Ignored if surface is a hemilist (in that case the surfaces have already been loaded).
simplify	logical, whether to return a vector instead of a single-row matrix in case only a single query vertex is given.

Value

nx3 numerical matrix, the MNI152 coordinates for the vertices closest to the given MNI305 query coordinates. Depending on the distance to the closest vertex, this may be way off. Also see the 'simplify' parameter.
