mesh.atlas.resolve.subjects.dir: Find a subjects dir that contains a mesh atlas for a subject.

In fsbrain: Managing and Visualizing Brain Surface Data

Find a subjects dir that contains a mesh atlas for a subject.

Description

Several locations can contain the data of a template subject like fsaverage, e.g.\ the package cache and the subjects dir of a FreeSurfer installation, and not all of them necessarily contain the mesh atlas. This function checks the locations in the order in which they are returned by find.subjectsdir.of and returns the first one that actually contains the atlas files. If none contains them, the first location found is returned, so that the caller can report the missing files.

Usage

mesh.atlas.resolve.subjects.dir(
  subject_id,
  atlas = "subcortical",
  surface = "subcortical"
)

Arguments

subject_id	string. The subject identifier.
atlas	string. The atlas name, used to construct the annotation file name.
surface	string. The name of the surface mesh that belongs to the atlas.

Value

string, the path of a subjects dir.
