Phylogenetic trees created by the tree tool can now be exported in the Newick format to be displayed by other tree-viewing programs

First define the sequences in the database you want to build a clustering or phylogenetic tree with. Select one name each from the lists provided, and/or fill in the boxes. Multiple queries can be built by clicking the "Add to Query Builder" button every time a new query is made, and queries in any combination from the Query Builder can be selected to get sequences in the database. The sequences will be shown in a separate window once you click the "Get sequences" button.
You will then have the option to build a clustering or phylogenetic tree using the dataset alone, or add your own sequences to the dataset.
