Checkerboard comparison of two registered volumes — plot

Alternates tiles from a background volume and a comparison volume on matched slices. This is useful for visual registration QC.

Usage

plot_checkerboard(
  bgvol,
  overlay,
  zlevels = NULL,
  along = 3L,
  tile = 16L,
  cmap = "grays",
  bg_range = c("robust", "data"),
  ov_range = c("robust", "data"),
  probs = c(0.02, 0.98),
  ncol = 3L,
  title = NULL,
  subtitle = NULL,
  caption = NULL,
  draw = TRUE,
  style = c("light", "dark")
)

Arguments

bgvol: Background/reference 3D volume.
overlay: Comparison 3D volume on the same NeuroSpace grid as `bgvol`.
zlevels: Slices to plot. Defaults to nine evenly spaced slices.
along: Native voxel-grid axis for slicing. Display orientation is inferred from the image affine.
tile: Tile width in slice pixels.
cmap: Palette used to render the normalized checkerboard image.
bg_range, ov_range: "robust" or "data" intensity scaling.
probs: Quantiles for robust scaling.
ncol: Number of columns in the facet layout.
title, subtitle, caption: Optional layout-level labels used when drawing.
draw: Logical; if `TRUE`, draw the panels on the active graphics device. If `FALSE`, only return the ggplot objects invisibly.
style: Visual style, either "light" or "dark".
