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'), a whole circuit ('motor/' or 'motor/*', which reaches into the circuit's sub-folders too), or just one of those sub-folders ('motor/left/*'). The default 'default/' loads the 'default' circuit, that is every streamline file placed directly under 'fs/streamline' as well as under 'fs/streamline/default' – the other circuits' folders are left alone. 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
