+<title>Extending Jalview with Groovy - Feature Counter Example</title>
+</head>
+<body>
+ <p>
+ <strong>Extending Jalview with Groovy - A customisable
+ feature counter</strong><br /> <br />The groovy script below shows how to
+ add a new calculation track to a Jalview alignment window.
+ </p>
+ <p>As currently written, it will add two tracks to a protein
+ alignment view which count Pfam features in each column, and ones
+ where a charge residue also occur.</p>
+ <p>To try it for yourself:</p>
+ <ol>
+ <li>Copy and paste it into the groovy script console</li>
+ <li>Load the example Feredoxin project (the one that opens by
+ default when you first launched Jalview)</li>
+ <li>Select <strong>Calculations→Execute Groovy
+ Script</strong> from the alignment window's menu bar to run the script on
+ the current view.
+ </li>
+ </ol>
+ <strong>Please note: The 2.10.2 feature counting interface is not compatible with earlier versions.</strong><br/><br/>
