Other phylogenetic trees
iTOL is used to generate trees in various projects. Some examples include:
- iPath: interactive Pathways Explorer
- metaTIGER: Metabolic Gene Evolution Resource
- eggNOG: evolutionary genealogy of genes: Non-supervised Orthologous Groups
Tree generator based on NCBI Taxonomy
Use this form to automatically generate a phylogenetic tree based on the full NCBI taxonomy tree. After parsing the complete NCBI taxonomy, iTOL will generate the pruned tree in Newick format, based on the information you provide. You can use the following:
- NCBI taxonomy IDs: they will appear as leaves in the generated tree, regardless of their taxonomic class. Classes can be mixed freely, ie. one ID can represent a species and another a phylum
- NCBI scientific names: make sure you provide the proper NCBI scientific name (including proper capitalization) and replace all spaces with underscores ('_'). For example, human should be specified using 'Homo_sapiens'
Our tree generator also supports generation of complete sub-trees for any NCBI taxonomy ID. To create a sub-tree for a NCBI taxonomy ID (or scientific name), simply append a vertical line followed by the keyword "subtree" (for example "Mammalia|subtree"). Sub-tree generation can also be interrupted at a specific NCBI taxonomic classes. Interruption is activated by appending the "|subtree" keyword with a dash and desired NCBI taxonomic class where sub-tree generation should stop. For example, if you specify "Mammalia|subtree-genus", leaves of the generated tree will correspond to nodes with class genus (such as Homo).
Unlimited number of sub-trees and regular taxnomy IDs or names can be specified at the same time.
