One website, two approach
Optimized phylogeny
This is a fully automated appoach to the phylogeny of Archaea and Bacteria by using SSU-rDNA (16S). You only need to write the query in the form, to choose or not a supplementary database and to run the process.
The procedure may automatically include some sequences of the secondary databases to improve the exploration of the variability of the sequences around the query position. An automatic search of a tree with a better topology is included.
Expert phylogeny
As an expert you will write the query in the form and then choose every available parameter. There are plenty of possibilities (although limited) and extended power. But you are also free to use the default choice.
Note that the procedure of including some sequences of the secondary databases to explore the variability of the sequences around the query position is not available. The automatic search of a tree with a better topology when needed is also absent.
