Description

Construct filepath of any freesurfer file.

Usage

subject.filepath.any(
  subjects_dir,
  subject_id,
  relative_path_parts,
  hemi = NULL,
  file_tag = "",
  warn_if_nonexistent = FALSE
)

Arguments

subjects_dir	character 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	character string. The subject identifier. Can be a vector of subject identifiers.
relative_path_parts	vector of strings. The path to the file, e.g., c("surf", "lh.area").
hemi	string, one of 'lh', 'rh', or NULL. Defaults to NULL. If a hemisphere name is given, it is added as a prefix to the last entry in relative_path_parts, separated by a dot.
file_tag	string. A one-word description of the file type that will show up in the error message to describe the file if it is missing. Leads to a better error message. Examples: 'morphometry' or 'label'. Only relevant if warn_if_nonexistent is TRUE. Defaults to the empty string.
warn_if_nonexistent,	logical. Whether to print a warning if the file does not exist or cannot be accessed. Defaults to FALSE.

Value

string, the file path. (Or a vector of strings if 'subject_id' is a vector).
