Generates a Brain Imaging Data Structure (BIDS) JSON sidecar using metadata tables (data dictionary and levels) without requiring the underlying data.

Usage

create_bids_sidecar_metadata(
  dd,
  levels,
  vars = NULL,
  tables = NULL,
  metadata_description = "Dataset exported using NBDCtools",
  path_out = NULL,
  pretty = TRUE
)

Arguments

dd

tibble, Data dictionary metadata, see get_dd() or provide a custom data dictionary. The custom data dictionary must have same structure as the official data dictionaries.

levels

tibble, Levels metadata corresponding to dd, see get_levels(), or provide a custom levels table. The custom levels table must have same structure as the official levels tables.

vars

character vector, variable names to include. vars and tables cannot be both NULL.

tables

character vector, table names to include.

metadata_description

string, the description of the metadata

path_out

character. the path to the output file. If NULL, the function will return the json object.

pretty

logical. Whether to pretty print the json.

Value

Either a JSON string (when path_out is NULL) or the output file path (invisibly) after writing the JSON sidecar to disk.

Details

  • If you have a labelled dataset, and want to create data specific BIDS sidecar with variable levels from the data, please use create_bids_sidecar_data().

  • If you want to create a BIDS sidecar without the underlying data, please use create_bids_sidecar_metadata().

Examples

create_bids_sidecar_metadata(
  dd = get_dd("abcd"),
  levels = get_levels("abcd"),
  tables = c("ph_y_mctq")
)
