vis.color.on.subject: 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,
  color_rh,
  surface = "white",
  views = c("t4"),
  rgloptions = list(),
  rglactions = list()
)

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.

color_rh

vector of colors to visualize on the right hemisphere surface.

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.

Value

list of coloredmeshes. The coloredmeshes used for the visualization.
