23 <title>Extending Jalview with Groovy - Feature Counter Example</title>

26   <p>
27     <strong>Extending Jalview with Groovy - A customisable
28       feature counter</strong><br /> <br />The groovy script below shows how to
29     add a new calculation track to a Jalview alignment window.
30   </p>
31   <p>As currently written, it will add two tracks to a protein
32     alignment view which count Pfam features in each column, and ones
33     where a charge residue also occur.</p>
34   <p>To try it for yourself:</p>
35   <ol>
36     <li>Copy and paste it into the groovy script console</li>
37     <li>Load the example Feredoxin project (the one that opens by
38       default when you first launched Jalview)</li>
39     <li>Select <strong>Calculations&#8594;Execute Groovy
40         Script</strong> from the alignment window's menu bar to run the script on
41       the current view.
42     </li>
43   </ol>
44   <strong>Please note: The 2.10.2 feature counting interface is not compatible with earlier versions.</strong><br/><br/>
