Create a brain object

Usage

threeBrain(
  path,
  subject_code,
  surface_types = c("pial", "smoothwm", "inflated", "sphere.reg"),
  atlas_types,
  annotation_types = "label/aparc.a2009s",
  ...,
  streamline_types = "default/",
  template_subject = unname(getOption("threeBrain.template_subject", "N27")),
  backward_compatible = getOption("threeBrain.compatible", FALSE)
)

Arguments

path: path to 'FreeSurfer' directory, or 'RAVE' subject directory containing 'FreeSurfer' files, or simply a 'RAVE' subject
subject_code: subject code, characters
surface_types: surface types to load; default is 'pial', other common types are 'white', 'smoothwm', 'inflated', 'sphere.reg'
atlas_types: brain atlas to load; default is 'wmparc', or if not exists, 'aparc+aseg', other choices are 'aparc.a2009s+aseg', 'aparc.DKTatlas+aseg', depending on the atlas files in 'fs/mri' folder
annotation_types: annotations, this can be one or more files relative to the 'FreeSurfer' subject directory. Each annotation can be discrete such as surface atlas, or continuous such as surface curvature.
...: reserved for future use
streamline_types: streamline (tractography) bundles to load from the 'fs/streamline' folder; passed straight to add_streamline, so each entry may name one bundle ('motor/AF_left') or a whole circuit group ('motor/' or 'motor/*'). The default 'default/' loads the 'default' circuit, that is every streamline file placed directly under 'fs/streamline' as well as under 'fs/streamline/default'. Use NULL to skip. Please note that each declared bundle is downloaded and parsed by the browser when the viewer starts, hence only one group is loaded by default; use add_streamline to add more.
template_subject: template subject to refer to; used for group template mapping
backward_compatible: whether to support old format; default is false
