## Historique du projet et usages
MAFFT is a multiple sequence alignment program for amino acid or nucleotide sequences. The official site describes MAFFT version 7 as software for Unix-like operating systems with a range of methods, including accurate L-INS-i for smaller alignments and fast FFT-NS-2 for larger sequence sets.
### Historique du projet
MAFFT originated as a fast Fourier transform-based approach to multiple sequence alignment, described in the 2002 Nucleic Acids Research paper cited by the official site. Subsequent official references trace major method and usability improvements through version 5, version 6, version 7, PartTree for large alignments, RNA structural alignment, multithreading, adding unaligned sequences, over-alignment control, large-data workflows, MPI parallelization, and MAFFT-DASH.
The official manual documents MAFFT as a Unix-style command-line program with aliases such as `linsi`, `ginsi`, `einsi`, `fftnsi`, `fftns`, `nwns`, and `mafft-profile`, each exposing a different speed/accuracy tradeoff.
### Historique d'adoption
MAFFT became a standard bioinformatics command-line package because it covers both routine and high-accuracy multiple sequence alignment workflows. The official site links to web services at EBI, MPI Bioinformatics Toolkit, GenomeNet, SIB MyHits, T-REX, DDBJ WABI, and CIPRES, showing adoption beyond a single downloadable CLI.
Package managers matter for MAFFT because alignment tools are commonly installed into reproducible research environments, HPC systems, and workflow managers. The supplied package facts show distribution through Homebrew, Debian, MacPorts, Nix, and Ubuntu, while the official site maintains source, Linux, macOS, and Windows download paths.
### Modes d'utilisation
The basic invocation is `mafft input > output` with FASTA input. The official site recommends `mafft-linsi input > output` as an accurate option for up to roughly 200 sequences and `mafft input > output` as a fast option for larger alignments, with `mafft --auto input > output` for automatic strategy selection.
The manual organizes MAFFT around algorithm families: accuracy-oriented L-INS-i, G-INS-i, and E-INS-i; speed-oriented FFT-NS and NW-NS variants; PartTree for very large sequence counts; and profile alignment for group-to-group workflows.
### Pourquoi les passionnés de paquets s'y intéressent
MAFFT is one of those scientific CLI packages that anchors entire downstream workflows. It matters to package maintainers because it has many executable aliases, platform-specific source/binary packaging, a long citation trail, and users who care about exact version behavior for reproducibility.
Its history also illustrates a common bioinformatics packaging pattern: a command-line core, official web services, and many package-manager builds coexisting because researchers need both interactive alignment services and scriptable local installs.
