  syn_data_params = params_sc_synthetic_data(
    n_cells = 500L,
    n_genes = 50L,
    n_batches = 2L
  )
)
symphony_ref <- build_symphony_ref(
  ref,
  batch_column = "batch_index",
  hvg = get_hvg(ref) + 1L,
  harmony_params = params_sc_harmony(k = 10L),
  no_pcs = 10L,
  label_columns = "cell_grp",
  .verbose = FALSE
)
