+<p><strong>Viewing Input Data to PCA and Tree calculations</strong></p>\r
+<p>It is always possible to retrieve the input data used to calculate\r
+ a tree or PCA plot by using the analysis window's \r
+ <strong>"File \r
+ -> Input Data..."</strong> menu item. The Input Data will be\r
+ shown in a new alignment window, with any hidden columns\r
+ preserved.</p>\r
