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

relative_path_parts

vector of strings. The path to the file, e.g., c("surf", "lh.area").

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).
