  # This method takes in the path to a protxml created in Galaxy,
  # finds the dependent pepxml and peak lists (mzml files), creates
  # symbolic links to the peak lists with the correct extension and
  # and indexes them if needed (both seem required for TPP quant
  # tools) and then produces new protxml and pepxml files with paths
  # updated to these new peak list files.
