coloredmesh.from.morph.native: Create a coloredmesh from native space morphometry data.

In dfsp-spirit/fsbrain: Managing and Visualizing Brain Surface Data

Create a coloredmesh from native space morphometry data.

Description

Create a coloredmesh from native space morphometry data.

Usage

coloredmesh.from.morph.native(
  subjects_dir,
  subject_id,
  measure,
  hemi,
  surface = "white",
  clip = NULL,
  cortex_only = FALSE,
  makecmap_options = mkco.seq()
)

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.
subject_id	string. The subject identifier.
measure	string. The morphometry data to use. E.g., 'area' or 'thickness'. Pass NULL to render the surface in white, without any data. One can also pass the pre-loaded morphometry data as a numerical vector, the length of which must match the number of surface vertices.
hemi	string, one of 'lh' or 'rh'. The hemisphere name. Used to construct the names of the label data files to be loaded.
surface	character string or 'fs.surface' instance. The display surface. E.g., "white", "pial", or "inflated". Defaults to "white".
clip	numeric vector of length 2 or NULL. If given, the 2 values are interpreted as lower and upper percentiles, and the morph data is clipped at the given lower and upper percentile (see clip.data). Defaults to NULL (no data clipping).
cortex_only	logical, whether to mask the medial wall, i.e., whether the morphometry data for all vertices which are *not* part of the cortex (as defined by the label file 'label/?h.cortex.label') should be replaced with NA values. In other words, setting this to TRUE will ignore the values of the medial wall between the two hemispheres. If set to true, the mentioned label file needs to exist for the subject. Defaults to FALSE.
makecmap_options	named list of parameters to pass to makecmap. Must not include the unnamed first parameter, which is derived from 'measure'.

Value

coloredmesh. A named list with entries: "mesh" the tmesh3d mesh object. "col": the mesh colors. "render", logical, whether to render the mesh. "hemi": the hemisphere, one of 'lh' or 'rh'.
