Mirror CRANT neurons or points to the opposite side of the brain

crant_mirror() mirrors objects supported by nat::xform(), including neurons, neuronlists, dotprops, meshes and coordinate matrices, across the CRANT brain midline.

Usage

crant_mirror(
  x,
  units = c("nm", "microns"),
  subset = NULL,
  reg = crantr::crant_mirror_tps,
  ...
)

Arguments

x: An object to mirror.
units: Coordinate units for x and the returned object. The mirror registration is defined in microns; nm inputs are scaled before and after transformation.
subset: Optional subset passed to nat::xform(), for example when transforming selected elements of a neuronlist.
reg: The mirror registration (in microns). Advanced use.
...: Additional arguments passed to nat::xform().

Value

A transformed object of the same kind as x.

Details

Mirroring uses the thin plate spline crant_mirror_tps and needs the suggested Morpho package at runtime.

Examples

if (FALSE) { # \dontrun{
# a point either side of the midline (x ~ 202 um)
crant_mirror(rbind(c(120, 200, 130), c(280, 200, 130)), units = "microns")

library(nat)
crantb.surf.m <- crant_mirror(crantb.surf)
wire3d(crantb.surf, col = "grey")
wire3d(crantb.surf.m, col = "red")
} # }
