context.mesh.resolve.subjects.dir: Resolve the subjects dir for a context mesh.

In fsbrain: Managing and Visualizing Brain Surface Data

Resolve the subjects dir for a context mesh.

Description

Determine the subjects dir from which the requested context mesh can be loaded, if the user did not pass one. For the template subject 'fsaverage' the surfaces are downloaded into the package cache if they are not available, for other subjects the standard search locations are checked, see find.subjectsdir.of.

Usage

context.mesh.resolve.subjects.dir(subject_id = "fsaverage", context = NULL)

Arguments

subject_id	string, the subject identifier.
context	the context mesh definition, as passed by the user, see vis.volume.clusters. A subject id and subjects dir can be part of this definition, in which case they take precedence.

Value

string, the path to the subjects dir to use, or NULL if the context mesh does not have to be loaded from disk (e.g., because it was passed as a pre-built mesh).
