        <p><strong>Pseudo-knots</strong><br/>
          Jalview 2.8.2 introduced limited support for working with structures including pseudoknots. Where possible, extended WUSS symbols (e.g. different types of parentheses, or upper and lower case letters) are preserved when parsing RNA structure annotation and will be shaded differently when displayed in the structure.<br/>
   Extended WUSS annotation is also employed to distinguish different base pair interactions obtained from RNAML files.</p>
