      <br>
      you could use phenix.find_tls_groups but the tool requires
      meaningfully refined B-factors and more or less good geometry so
      the secondary structure can be identified automatically. If this
      is your case then phenix.find_tls_groups might work for you.<br>

        The latter....something more analytical to split individual
        chains into smaller groups
        <br>
        (e.g. like to define tls groups).<br>
