In dfsp-spirit/regfusionr: Registration Fusion in R

Transform MNI305 coords (FreeSurfer fsaverage surface) to MNI152 coordinates using the linear method.

Description

This uses the 4x4 matrix from the FreeSurfer Coordinate Systems documentation.

Usage

linear_fsaverage_coords_to_MNI152_coords(vertex_coords)

Arguments

vertex_coords

nx3 matrix of coordinates, e.g., typically from fsaverage surface vertices.

Value

nx3 numerical matrix if MNI152 coords.

Note

This is the opposite of using the Wu et al. approach: a linear transformation matrix is used. This approach is mainly implemented in this package to allow you to easily check the difference between the methods.
