GENERATING A PHYLOGENTIC TREE

Step 4: ClustalW guide tree

The guide tree is available for download as a .dnd file and contains the information for building the cladogram or phylogram. The ".dnd" file is a file that describes the phylogenetic tree.

A Phylogram is a branching diagram (tree) assumed to be an estimate of a phylogeny, branch lengths are proportional to the amount of inferred evolutionary change.

A Cladogram is a branching diagram (tree) assumed to be an estimate of a phylogeny where the branches are of equal length, thus cladograms show common ancestry, but do not indicate the amount of evolutionary "time" separating taxa.

These options are now in controlled with new buttons in the output file as well as a pop up menu, that is available by right-clicking on the applet. The buttons on the page include "Show as Phylogram Tree", "Show as Cladogram Tree" and "Show Distances".
Tree distances can be shown, just click on the diagram to get a menu of options.
