+Aptx can be used to display vector or expression data associated with tree nodes:
+
+ # Ensure the configuration file contains this line: "show_vector_data: display yes"
+ # Start Aptx and read in a tree ([http://forester.googlecode.com/files/apaf.xml example tree])
+ # Open "Tools" menu and select "read Vector/Expression Values" to read in a matrix (of, for example, expression values) ([http://forester.googlecode.com/files/apaf_expression.tab example expression values])
+
+It is also possible to store vector data in phyloXML formatted files ([http://forester.googlecode.com/files/apaf_with_vector_data.xml example]).
