is a multiple sequence alignment program for
unix-like operating systems.
It offers a range of multiple alignment methods,
L-INS-i (accurate; for alignment of <∼200 sequences),
FFT-NS-2 (fast; for alignment of <∼10,000 sequences), etc
Download and Installation
The latest version is 7.130 (2013/Dec/11).
The gap scoring scheme has been changed in version 7.1xx.
The new version tends to insert more gaps into gap-rich regions.
To disable this change, add the --legacygappenalty option.
Fasta format. example1 (LSU rRNA)
The type of input sequences (amino acid or nucleotide)
is automatically recognized.
% mafft [arguments] input > output
An alias for an accurate option (L-INS-i) for an alignment of up to ∼200 sequences × ∼2,000 sites:
% mafft-linsi input > output
A fast option (FFT-NS-2) for a larger sequence alignment:
% mafft input > output
If not sure which option to use,
% mafft --auto input > output
