vis.color.on.subject: Visualize pre-defined vertex colors on a subject.

In fsbrain: Managing and Visualizing Brain Surface Data

Visualize pre-defined vertex colors on a subject.

Description

Visualize pre-defined vertex colors on a subject.

Usage

vis.color.on.subject(
  subjects_dir,
  vis_subject_id,
  color_lh = NULL,
  color_rh = NULL,
  surface = "white",
  views = c("t4"),
  rgloptions = rglo(),
  rglactions = list(),
  color_both = NULL,
  style = "default"
)

Arguments

subjects_dir	string. The FreeSurfer SUBJECTS_DIR, i.e., a directory containing the data for all your subjects, each in a subdir named after the subject identifier.
vis_subject_id	string. The subject identifier from which to obtain the surface for data visualization. Example: 'fsaverage'.
color_lh	vector of colors to visualize on the left hemisphere surface. Length must match number of vertices in hemi surface, or be a single color.
color_rh	vector of colors to visualize on the right hemisphere surface. Length must match number of vertices in hemi surface, or be a single color.
surface	string. The display surface. E.g., "white", "pial", or "inflated". Defaults to "white".
views	list of strings. Valid entries include: 'si': single interactive view. 't4': tiled view showing the brain from 4 angles. 't9': tiled view showing the brain from 9 angles.
rgloptions	option list passed to par3d. Example: rgloptions = list("windowRect"=c(50,50,1000,1000)).
rglactions	named list. A list in which the names are from a set of pre-defined actions. The values can be used to specify parameters for the action. The following example clips outliers in the data before plotting and writes a screenshot in PNG format: rglactions = list("snapshot_png"="~/fsbrain.png", "clip_data"=c(0.05, 0.95)). See rglactions.
color_both	vector of colors to visualize on the left and right hemispheres. Alternative to 'color_lh' and 'color_rh'. Length must match sum of vertices in both hemis. Can also be a hemilist.
style	character string or rgl rendering style, see get.rglstyle.

Value

list of coloredmeshes. The coloredmeshes used for the visualization.
