MAFFT help

A brief introduction to MAFFT
MAFFT identifies homologous regions rapidly by means of the fast Fourier transform (FFT). MAFFT is classified as a similarity-based method and takes evolutionary information into account. MAFFT 7 has several new features, including options for adding unaligned sequences into an existing alignment, adjustment of direction in nucleotide alignment, constrained alignment and parallel processing, which were implemented after the previous major update.

Availability in NPS@
MAFFT is available :

The set to align cannot have more than 1,000,000 characters.
So, for example, you can use MAFFT to align a set of similar sequences built from a BLAST search.

Different alignment strategies are available, as well as sequence output order and output tree file generation.
The output format is CLUSTAL W.

NPS@ MAFFT output example
The NPS@ MAFFT output is divided into three parts.
