  ## use a daf file

  daf <- ExtractFromDAF(fileName = file_daf)
  ## copy 1st region found in daf
  reg <- daf$regions[[1]]
  if(length(reg) != 0) {
    reg_copy <- reg
    ## modify region label and x boundaries
    reg_copy$label <- paste0(reg_copy$label,"_copy")
    reg_copy$x <- reg_copy$x*0.9
    ## create new object with this new region
    dafnew <- data_add_regions(obj = daf, regions = list(reg_copy))
