fsaverage_vertices_to_colin27_coords: Map fsaverage vertex indices to Colin27 coordinates.

In dfsp-spirit/regfusionr: Registration Fusion in R

Map fsaverage vertex indices to Colin27 coordinates.

Description

Map fsaverage vertex indices to Colin27 coordinates.

Usage

fsaverage_vertices_to_colin27_coords(
  vertices,
  hemis,
  fs_home = Sys.getenv("FS_HOME"),
  simplify = FALSE
)

Arguments

vertices	integer vector of vertex indices (1-based), the n fsaverage vertices you want to map.
hemis	vector of character strings, the hemispheres of the query vertices. Each entry in the vector has to be either 'lh' or 'rh'. Length must match length of parameter vertices.
fs_home	character string, path to the FreeSurfer installation. Alternatively, a hemilist of freesurferformats::fs.surface instances like surface = list("lh"=mysurflh, "rh"=mysurfrh). Used to find the surfaces, at <fs_home>/subjects/fsaverage/surf/<hemi>.<surface>, where hemi is 'lh' and 'rh'. Can be NULL if 'surface' is a hemilist of fs.surface instances.
simplify	logical, whether to return a vector instead of a single-row matrix in case only a single query vertex is given.

Value

matrix of dim n x 3, the MNI152 coordinates for the query vertices, one row per vertex. Also see the 'simplify' parameter.
