load Freesurfer ascii surface

Usage

loadFSSurface(meta_info, surf_to_world = diag(4))

Arguments

meta_info: instance of type FreesurferSurfaceGeometryMetaInfo
surf_to_world: Optional 4x4 affine transformation matrix from surface (tkr-RAS) coordinates to world (scanner RAS) coordinates. Defaults to identity. For proper alignment with volumes, this transform can be computed from FreeSurfer's vox2ras-tkr matrix (available in orig.mgz or via mri_info –vox2ras-tkr).

Value

a class of type SurfaceGeometry

Details

requires rgl library

Examples

# \donttest{
# Requires FreeSurfer surface file
# meta <- read_meta_info(FreesurferAsciiSurfaceFileDescriptor(), "lh.pial.asc")
# geom <- loadFSSurface(meta)
# }
