The program accepts a wide range on input formats including: NBRF/PIR, FASTA, EMBL/Swissprot, Clustal, GCC/MSF, GCG9 RSF, and GDE, and executes the following workflow:
- Pairwise alignment
- Creation of a phylogenetic tree (or use a user-defined tree)
- Use of the phylogenetic tree to carry out a multiple alignment
Users can align the sequences using the default setting but occasionally it may be useful to customize one's own parameters. The main parameters are the gap opening penalty and the gap extension penalty.
