ATV (A Tree Viewer) is a Java tool for the visualization of annotated phylogenetic trees. ATV reads standard New Hampshire format tree files (as produced by all major phylogenetic analysis software). ATV also implements an extended superset of New Hampshire format of our own design, called NHX format, which allows to extensively annotate a tree (a definition of NHX is available at: http://www.genetics.wustl.edu/eddy/forester/NHX.html).

ATV can be used both as an application and as an Applet. Two versions of ATV exist: One requires Java 2, the other one only requires Java 1.1.x (but has less functions). ATV is part of FORESTER (a framework for automated phylogenomics).
