WELCOME TO ITOL V6

Interactive Tree Of Life is an online tool for the display, annotation and
management of phylogenetic and other trees.

Manage and visualize your trees directly in the browser, and annotate them with
various datasets.


TREE ANNOTATION MADE EASY.

Annotate your trees directly from Microsoft Excel, LibreOffice or Google Sheets,
or use the integrated web dataset editor. Advanced users can create the dataset
template files and drag/drop them directly onto the tree, with complete control
of all visualization options.

Adjust branch and label colors, styles and fonts interactively or by using
annotation template files.


UNLIMITED NUMBER OF DATASETS.

All datasets can be be displayed simultaneously, with fine-grained interactive
control of their position, size and other visualization parameters.

Branch support values and other metadata can be visualized as various shapes
with adjustable colors and sizes or as text labels. Alternatively, branch colors
or widths can be linked to the underlying data values.
