Build a phylogenetic tree

1. Collect a list of needed sequences.
2. Do multiple sequence alignment, for example mafft (mafft –localpair –maxiterate 1000 a.fa > a.ali).
3. Build a phylogenetic tree, for example FastTree (FastTree a.ali > a.nwk).
4. Visualize the phylogenetic tree, for the iToL (http://itol.embl.de/) web server.
