Details: This tool groups sequences based on sequence names, and draws a color-coded tree using up to 20 colors. It is useful when you already have a tree and want to color its branches to depict particular groupings of sequences. For example, the Sample Input with default settings depicts the HIV-1 M-group reference phylogeny color-coded by subtype.
